  • Page 24: Taking A Reading

    Taking a reading Fill the polarimeter tube with your sample. Gently rock the tube from end to end to ensure all air bubbles are released through the centre filling tube. Lift open the chamber cover and place the tube on the two rails. The instrument will now start taking readings continually.

  • Page 25: Zeroing The Reading

    Zeroing the reading The instrument should be zeroed often to ensure accurate readings. It is a quick and simple procedure so can easily be carried out before every measurement. There must be no sample present and so it can be done with an empty chamber or, if preferred, with the polarimeter tube that will be used to measure the sample.

  • Page 26: Optical Density

    If the optical density of the sample is greater than 3, the background of the reading area will appear grey, show below (see page 2-10). Temperature sensor The ADP440 has a in-built temperature sensor. The measured temperature will automatically be updated and displayed in degrees Celsius. The probe is found inside the measurement chamber.

  • Page 27: Printing The Readings

    Printing the readings If the fourth (right hand) softkey is set to ‘Print’ or ‘Prt+Save’, the last displayed reading can be sent to a printer via the selected port. The print layout can be either with the reading data listed sequentially, suitable for narrow printers with 24 columns, or with the data in CSV (comma separated values) suitable for connection to a LIMS.

  • Page 28: The Instrument Logs

    The instrument logs The ADP440 polarimeter has two separate logs for storing data. This data will be held in the instrument whether or not the power is on or off and can be downloaded to a computer using the ADP Log Acquisition Program (see below).

  • Page 29: Measurement Settings

    Measurement Settings The measurement settings are accessed in the Mode menu, which is available from the Measurement Display. Mode menu The mode menu will be familiar to users of the ADP220 polarimeter and many other Bellingham + Stanley instruments. The measurement settings are changed from the Mode menu, which is accessed from the Measurement Display.

  • Page 30: Measurement Settings In Detail

    Measurement settings in detail The ADP440 has a number of measurement settings… Scale (the scale units that the readings is displayed in) Temp. Comp. (whether temperature compensation is used) Limits (tests to check if the reading parameters are within set...
  • Page 31 Angular degree range The Range setting is only available when the angular degree scale (°a) is selected. The default range for the °a scale is -89° to +89° (std). The “(std)” has been added to this one range title to allow easy identification of the standard range.

  • Page 32: Remote Operation

    Remote operation Operation of the ADP440 can be controlled remotely from a computer via the RS232 Serial port. The 54-07 interconnecting cable optionally available from Bellingham+Stanley will connect to the COM port of a typical PC. Use a proprietary terminal program or custom software to send commands and receive data.

  • Page 33: Rs232 Serial Port

    RS232 serial port The RS232 serial ports can be accessed via the 9 pin “D type” connectors on the rear of the instrument. The interconnecting cable socket can be secured with the 2 screws but these must be finger-tightened only – DO NOT OVER- TIGHTEN..

  • Page 34: Sampling Techniques

    Sampling techniques In order to achieve the maximum performance from the ADP440 Series polarimeter, it is essential that extreme care is taken with cleanliness of the instrument and the polarimeter tubes. Allow the instrument to stabilise for at least 30 minutes after switching on before taking accurate readings.

  • Page 35: Cover Glass Stress

    Cover glass stress As stated above, excessive tightening of an end cap can cause stresses in the cover glass which will cause optical rotation in the glass itself and so give a measurement error. The reading displayed will be a combination of the rotation of the sample and the rotation in the glass.

  • Page 36: Flow-Through And Water-Jacketed Tubes

    Flow-through and water-jacketed tubes When using optional water-jacketed polarimeter tubes, the standard upper lid should be replaced with a slotted type, see ‘Section 5, Accessories’. Mechanically compatible ADP410 model shown The upper lid can be easily removed by unscrewing the hinge block retaining screws using a standard 4mm Allen key.

Regardless as to how the measurement settings are selected the instrument has the following measurement settings.

  • Page 47: Methods

    Methods A method is a set of measurement settings options. This allows the measurement settings to be changed quickly between frequently used configurations. Initially, there are two methods set in the instrument: normal for measuring samples span the conditions used for a ‘span’ calibration The span profile does not contain the Range settings.

  • Page 48: Editing An Existing Method

    Editing an existing method press the Menu softkey select 3. Setup select 1. Methods select the method to be edited To delete a method select option 6. which is Delete Method. Hiding the normal methods If the polarimeter will always be used with the normal method, i.e. one set of conditions for all samples, and no other profiles have been added, then the Methods function can be disabled and the second softkey in the Measurement display will be blank.

  • Page 49: Method Selection Type

    Method selection type Before reading a sample, the relevant method should be selected by pressing the Method softkey in the Measurement Display. This will show a list of all available methods and the appropriate one can be selected. However, if a large number of methods have been created, e.g. greater than 20, then it could be easier to select the required method by its index number rather than scrolling through the list.

  • Page 50: Reading Limits

    Reading limits Reading Limits allows up to three test conditions to be set. If any of the reading parameters values fall outside the limits then the reading is identified as ‘fail’. The three test conditions can be set to check any, or all, of the available parameters.
