  • Page 5: Introduction

    Universal ATR Sampling Accessory User’s Guide . 5 Introduction The Universal Attenuated Total Reflectance Accessory (UATR) is an internal reflection accessory, used with a Spectrum Two Series spectrometer, for simplifying the analysis of solids, powders, pastes, gels and liquids. The technique is non-destructive.
  • Page 6 Force may be applied to ensure good contact. The Spectrum Two UATR uses a diamond crystal. The diamond crystal is hard, is not easily scratched, is resistant to strong acids and bases, and can withstand high pressures. The diamond UATR has an effective scanning range that matches the full range of the instrument, although sensitivity is somewhat reduced in the approximate range 1900–...

    Universal ATR Sampling Accessory User’s Guide . 7 Unpacking the UATR As soon as you receive your UATR Accessory, make sure that it includes the parts listed below. If anything is missing or damaged, contact your local PerkinElmer office. The UATR Accessory itself is shipped fully assembled and ready to install.

    Contamination from the Ready Checks available. The Ready Checks dialog is displayed. 2. Make sure that you have removed any sample from the UATR and cleaned the crystal, and then click Scan. A new background spectrum is collected, compared to the reference background spectrum (a spectrum taken when the crystal is known to be totally clean), and the result of the test displayed.

  • Page 12: Performing Ready Checks That Use Polystyrene

    Some of these Ready Checks, including Abscissa Check and Ordinate Check, use a polystyrene sample as reference. A polystyrene sample that can be used on the top-plate of your UATR is provided for use when carrying out these Ready Checks.

  • Page 13: Handling Samples

    Good contact between the sample and the surface of the crystal is important to prevent loss of beam penetration. To aid this good contact the UATR pressure arm can be used, in conjunction with a “shoe”, to apply a controlled force to the sample and make better contact with the crystal.

  • Page 14: Obtaining A Sample Spectrum With Spectrum Software

    Software The following pages outline the procedure for obtaining a sample spectrum using a Spectrum Two instrument fitted with a UATR and running Spectrum software. For further information on how to use Spectrum software, see the on-screen help provided. NOTE: When you first fit the accessory, the software automatically sets default scan parameters to values that are appropriate to the UATR.
