UATR Accessory for Frontier, Diamond/ZnSe (9 Reflection)

The Universal ATR is an excellent general accessory for the analysis of solids and liquids, producing high quality spectra through the use of a pressure arm, allowing for good contact of the sample with the diamond/ZnSe crystal. The Spectrum 3/Frontier system ships basic transmission mode functionality (sample holder) as standard. There is a wide range of PerkinElmer sampling accessories available for the Spectrum 3/Frontier instruments. For the widest range of MIR applications, we recommend the Spectrum 3/Frontier UATR Accessory.

The Universal ATR includes a pressure arm with a force indicator to ensure first-class sample-to-sample and operator-to-operator reproducibility of measurements. The accessory is automatically recognized when it is placed in the sample compartment, the optics are immediately optimized, and the system is ready to be used without any additional alignment.

Features of the UATR include:

  • Automatic recognition - as soon as the accessory is placed in the sample compartment the Universal ATR module is recognized along with its unique number, and system suitability checks can be carried out.
  • Zero alignment, zero set-up - once locked into the instrument, the system is ready to be used without any alignment necessary.
  • Integration - the plug-in module design means the accessory becomes an integral part of the instrument once installed.
  • Live spectral preview mode and force readout in Spectrum software to ensure good contact with the crystal before scanning.
  • Volatiles cover supplied as standard with this nine reflection crystal for optimal sampling of volatile liquids.
