Infared Detectors


IR5 MCT is an infrared detector designed to determine on-line concentration and composition. It incorporates a high temperature flow through cell, interference filters at five different wavelengths and a high sensitivity thermoelectrically cooled MCT (Mercury Cadmium Telluride detector) with no requirements of liquid Nitrogen.

IR5 MCT detector incorporates a vapor leak sensor close to the flow through cell and internal temperature controllers for the heated cell and transfer line to allow its safe use for high temperature applications.


  • High sensitivity concentration and composition detector for GPC analysis of Polyolefins.
  • High sensitivity MCT sensor with no liquid nitrogen requirements.
  • Special focus on HDPE resins analysis by GPC-IR.
  • Outstanding baseline stability.
  • Possibility of coupling it to Polymer Char’s GPC-IR , CEF or CFC integrated into the instruments or to third party high temperature systems as stand-alone detector.
  • Thermoelectrically cooled MCT sensor. Liquid Nitrogen not required.
  • Different filters for detection at different bands in the MID-IR.
  • Internal temperature controllers for high temperature flow through cell and transfer line.
  • Built-in safety measures: vapor sensor for solvent leak detection and maximum temperature protection.
  • Virtual Instrumentation software package to control the instrument and acquire all the sensors signals.
  • Potential applications with other type of polymers such as polycarbonate, styrene-butadiene copolymers, epoxy resins, PET or PBT.
