QualiFT-IR 5000 Spectrophotometer from Qualitest

Infrared (IR) spectroscopy is a widely used analytical technique both for identification and quantification of a vast range of materials.

Qualitest offers a wide variety of laboratory FTIR spectrometers for verify the identity and specifications of raw materials and products. The QualiFT-IR 5000 Spectrophotometer is built on an upgraded integration electronic system that is designed with highest flexibility and stability. It also comes with more powerful software, especially FDA CFR 21 program.


  • Powerful MainFTOS Suite software comes with specialized IR libraries, real-time instrument status diagnosis, modular platform design, FDA CFR 21 Part 11 Compliance, and auto software updating. It is also compatible with all windows versions.
  • High sensitivity optical system ensuring long term stability, without the need of dynamic alignment which needs extra complicated electronic circuits.
  • High stability modular partition design greatly improves the mechanical stability and long term working stability of the instrument.
  • Intelligent multi-sealed moisture-proof design for preventing influences of high temperature, high humidity and chemical corrosions to the optical system in many ways.
  • Innovated integration electronic system ensuring high quality real-time data collection and high-speed transmission.
  • The electronic system is designed to meet CE certification and electromagnetic compatibility requirements, minimizing electromagnetic radiation in design and technology.
  • High intensity, long lifetime IR source module, with the highest energy distributed in fingerprint region, adopts a reflex sphere design to obtain even and stable IR radiation.
  • The sampling compartment reserving accessory mounting holes on the base plate, is designed for various accessories such as Defused/Specular Reflection, ATR, Liquid cell, GaS cell, and IR microscope etc.
