Details

The NIRQuest is a versatile NIR spectrometer for applications ranging from moisture detection to laser characterization. NIRQuest spectrometers cover the wavelength range from 900-2500 nm. Custom and preconfigured options are available.

Example Applications
• Determination of moisture content in grains
• QA/QC inspection of pharmaceutical ingredients
• Measurement of blood oxygenation in tissue
• Component analysis of soil samples
• NIR laser characterization
• Hydrocarbon analysis in oil and gas
• Photoluminescence of coated silicon wafers
• Determination of chemical composition of plastics

Overview

  • Robust -- reliable spectrometer with deep thermoelectric cooling to -20 °C for low dark current
  • Fast spectral processing -- rapid data transfer is great for applications using chemometric models
  • Modular -- configurable with a range of detectors, gratings and slits for your application
  • Flexible -- replaceable slit design and optional internal shutter for adaptable measurement control
