Sample Cells: Better By Design

Many Rudolph Polarimeter Cell designs offer significant advantages over traditional fused end glass cell designs as shown in Picture B. All glass cells are easily broken and often build up optically active residue on the inside of the glass ends. Also these cells do not have built in apertures so the light passing through the sample is easily affected by small air bubbles caught inside the cell as shown in Picture B. Rudolph does offer this style cell for those customers who prefer a fused glass end cell for use in their polarimeter or saccharimeter but doesn't recommend them

alt

Rudolph Polarimeter Cells with built in apertures eliminate these problems because the stainless steel screw ends have apertures that are smaller than the internal diameter of the cell body to avoid the problem of the light being disturbed by small air bubbles along the surface of the cell. This design results in better optical rotation measurement stability (Figure 2).

As shown below, the screw caps have precision apertures which reduce the beam diameter to less than the internal diameter of the cell so that, when the cells are aligned with the beam, internal sidewall reflections and consequent depolarizing effects are minimized.

alt

Easy Cleaning
Another advantage over fused end cells is that screw caps, washers, and end plates are easily removed for cleaning the glass ends, sample cell interiors, or for replacement of the washers and end glass. To reassemble the cell requires following the configuration of Figure 2 and then applying finger tight pressure to the screw caps. As the screw caps are turned, the washers are compressed against the end glass creating a leak proof seal with the precision ground cell ends. Minimal screw cap pressure and the compressibility of the washer ensures a tight seal without causing stress induced birefringence in the glass end plates.

Sample Cell Selection
Cells That Meet The Most Demanding Applications
With over 50 cells to choose from, Rudolph Research Analytical has a cell to meet every application.

alt 

Autopol®s Accept Sample Cells from 10mm to 200mm Long
Some polarimeters accept only special sample cells, with maximum lengths of 100mm. Autopol®s accept cells up to 200mm long. A 200mm sample cell offers twice the sensitivity when measuring the same solution in a 100mm cell. This additional optical path length is especially useful for solutions that have a small optical rotation. For precious samples and essential oils that have a large optical rotation, cells with only 0.05ml volumes and 10mm optical path lengths are available.

Continuous Sampling Capability

Access through gasketing in the top of the sample trough easily allows connection to a process stream (Figure 3). Readings can be downloaded via RS232 to a computer at fixed intervals or when prompted by an operator or an ASCI II command. Custom cells with special Swagelock® ferrules and fittings, and NEMA enclosures (as shown below) are available to allow connection to process streams.

 alt

Figure 3: Continuous Sampling

Picture C: Pour In Sampling With Temperature Correction

alt

Picture D: Micro Volumes for HPLC

Easy Filling
Sample solutions are either poured, injected with a syringe or pipetted into the center well, side well or side tubulation. Air bubbles are released by tilting the cells side to side or to one side while filling. Flexible tipped pipettes capable of reaching from the center well to either end of the sample can be helpful in filling narrow bore center fill cells.

Micro Volumes for Chiral Detection After HPLC
If your application demands 1ml or less, Type 32 Cells offer less than 0.5ml volumes. These cells come standard with HPLC fittings which transform your polarimeter into a chiral detector when connected to a chiral column after HPLC (Picture D).

Pour In Sampling Capability
Rapid operation is achieved by using a Type 31 or 33 Flow Through Polarimeter Sample Cell as seen in Picture C. Once the sample cell is filled, each successive sample poured into the funnel will displace the previous sample through the drain tube. This method eliminates opening and closing the polarimeter or saccharimeter sample chamber door and interchanging sample cells. Measurements can be made about as rapidly as successive samples can be poured.

Temperature Correction
For sucrose or other high volume applications where the temperature coefficient is known, a 33 Cell can be used as in Picture C. This cell has a built-in temperature port which, when the temperature probe is inserted, automatically measures the sample temperature inside the cell and sends the temperature to the Autopol® IV or Autopol® 880 for correction to 20°C, 25°C or any customer specified temperature.

Two Temperature Control Solutions
Patented TempTrol™ Technology Eliminates the Need for a Water Bath

TempTrol heating and cooling transfer surface

Temperature is selected via touch screen

TempTrol cell with mating heating and cooling transfer surface

Place the TempTrol cell in your TempTrol equipped Autopol® IV or V sample chamber to measure to within ±0.2°C of the USP, EP, JP, or BP specified temperature (normally 20°C or 25°C ±0.5°C)

Rudolph provides a temperature validation cell with every TempTrol system. The temperature validation cell along with an optional NIST traceable thermometer is designed to validate the temperature control performance of the polarimeter and cell to ±0.2°C.

Temperature Control With Water Bath

As seen above, almost all Rudolph Research Analytical jacketed cells come standard with quick release fittings which allow cells to be easily removed from the polarimeter or saccharimeter sample chamber. Tubing is held in place by rubber gasketing on top of the trough and the door. Optional stopper (choose "S" after the cell part no.) for evaporative samples (Picture A).

alt

Temperature control is obtained through the use of an external water bath and a jacketed cell (Figure 1).

Why Choose an Automatic Rudolph Saccharimeter?

Just listen to our customers:

…how pleased we are with the AUTOPOL instrument here at Lula-Westfield. Its performance has proven to be both reliable and accurate…

— A.H. Newchurch, Jr., Chief Chemist, Lula-Westfield, USA
…the biggest difference I’ve seen having the AUTOPOL 880 is how stable the readings are even with dark samples. There is no guessing the final answer.
— Arnel Negranza, Chief Chemist, Western Sugar, USA


Autopol® 589, 880, and 880T, and 880 Plus Saccharimeter Important Features

Dual Wavelengths

The most important feature of the AUTOPOL® models IIZ, 880, 880 Plus and 880T are their ability to measure at two wavelengths: 589 nm and 880 nm (NIR). Select 589 nm for conventional analysis using chemicals or lead clarifiers, or select 880 nm for polarimetric sugar measurements in the near infrared (NIR). 880 nm is above the absorption level of most dark sugar factory solutions allowing measurement of filtered but non-lead clarified juices. The dark sample measurement bar gets darker in proportion to the darkness of the sample being measured. When the bar is completely dark the instrument has reached its measurement limit.

alt 

Dilution and Cell Length Correction

Whether your sugar analysis requires a 25mm, 50mm, 100 mm or 200 mm cell, whether you use 1/2 normal (13g/100ml), 1/4 normal (6.5g/100ml) or full weight sugar solutions, the AUTOPOL® 589, 880, 880 Plus and 880T saccharimeters provide the correct multiplier to display the reading as if the sample were prepared as a 1 normal solution in a 200 mm optical pathlength cell.

 alt

Automatic Saccharimeter Calibration

Calibrating the AUTOPOL® is quick and simple. First, place a Rudolph Quartz Control Plate calibration standard on the optical rails and enter the Quartz Plate value in the appropriate window. Second, enter the temperature to correct the measurement to either the ICUMSA standard temperature of 20°C or the Tropical reference temperature of 27.5°C. Third, press 2 buttons and calibration is complete. (See Technical Bulletin 913 for more details on Rudolph Calibration Standards)

 alt

Automatic Temperature Correction

All AUTOPOL® Saccharimeter models have a temperature probe in the measurement compartment. The probe can be inserted into all 14 style, 40T style, 41T style and 33 style measurement cells.
The AUTOPOL® displays the temperature source and type of correction. Utilizing factory programmed temperature coefficients the AUTOPOL® can make the following types of temperature corrections:

 alt
  • A 30° C sucrose sample can be measured by the temperature probe and corrected to 20°C or 27.5°C or a customer defined temperature.
  • A 29°C sucrose sample in a Type 14 center fill glass cell can be measured by the temperature probe inside the saccharimeter sample chamber and corrected to 20°C.
  • A Quartz Plate measured at 25°C by the chamber temperature probe and then automatically corrected to 20°C.

Below is an example of why Polarimeters with accuracy of ±0.02 and ±0.01 accuracy polarimeters are not suitable for pharmaceutical applications. Please review the USP monograph for the material Ofloxacin. Ofloxacin must have a specific rotation between +1° and -1° at a concentration of 10mg per ml. Biots Law:
formula_1
The Autopol I has an accuracy of ±0.02° optical rotation. Below is how its relative accuracy affects a hypothetical Ofloxacin sample:
formula_2
You cannot successfully inspect a pharmaceutical (such as Ofloxacin) having a Specific Rotation between+1 and ±1 and a 1% concentration, which is quite common for most pharmaceuticals, with an instrument that has an accuracy of ±2.0 in Specific Rotation.The Autopol IV has an accuracy of 0.002 for Optical Rotations of 1°Arc for a total unknown of +/-0.002 under the same conditions:

Full 21CFR Part 11 Instrument Level Compliance

  • The DDM 2911 and DDM 2910's 21CFR Part 11 software module is easily enabled through the user friendly touch screen. This module gives you full compliance with:
  • Electronic Signature
  • Access Levels
  • Internal write protected storage
  • Unique passwords
  • Write protected documents sent directly to server

Oscillating U-Tube with Viscosity Correction and Reference Oscillator
(patent pending)
The DDM 2911 and DDM 2910's oscillating U-tube with full range viscosity correction and reference oscillator (patent pending) allows long term calibration stability and measurement at all temperatures with a single calibration.


cGMP/GLP Calibration

  • Calibrate the DDM 2911 and DDM 2910 with 2 or 3 Traceable Standards - calibrating with merely air and water appears inconsistent with cGMP/GLP compliance regulations. (see H&D Fitzgerald's recommendations at www.density.co.uk)
  • Can print out complete method configuration, communication settings, as well as calibration verification and calibration adjustment data/history.
  • Measured values can be shown continuously as temperature stability is being reached or, at the discretion of the user, measured values will only be displayed once the final answer is reached and completely stable.
  • Unlimited number of customized calibration adjustments and calibration verifications possible.

densitometer_05

Computer Windows Based Flexibility

  • 8 gigabytes of internal memory allow almost unlimited capacity for saving measurement data. The DDM 2911 and DDM 2910 are network ready and data may also be saved directly to your server or to any directory desired.
  • Internet access is possible directly from the DDM 2911 and DDM 2910's touch screen.
  • Disk Protection feature protects the operating system against malware infections in networked environments.
  • Windows based navigation architecture is so intuitive that most operators will never read the manual. But should you wish to reference the manual, it is stored right on the DDM 2911 and DDM 2910's internal memory
  • Copy methods, transfer concentration tables, download data, etc., via a USB port on front of unit.
  • Three USB ports allow for quick and easy connection to a mouse, keyboard, printer, bar code scanner, or memory stick.
densitometer_06

Versatile Communication Capability
The DDM 2911 and DDM 2910's standard communication package includes:

  • Cat 5 Network Cable Connection
  • 3 USB ports
  • 2 RS 232 Ports

Allowing capability to:

  • Export measurement results to a thumb drive, store it locally on the C:\ drive, or easily send data to any external PC, LIMS, etc.
  • Print measurement results to a local or networked printer. Use any printer; just load the proper printer driver as you would with any PC.
  • Save measurement data direct to your Network/Server
densitometer_07

cGMP/GLP Printing
Sample measurement reports are edited quickly and easily. Just import templates from Word® or Excel® to the DDM 2910 or DDM 2911 Density Meter and print your company's customized "C of A" directly.
