Description
The NIRQuest+2.5 is a versatile NIR spectrometer for applications ranging from moisture detection to laser characterization. It is responsive from 900-2500 nm, while other NIRQuest+ models cover different ranges within 900-2500 nm. Custom and preconfigured NIRQuest+ options are available.
NIRQuest+2.5 can measure very small changes in absorbed signal, which are typical of harmonic overtones in the NIR. Its higher sensitivity enables better measurement accuracy, particularly in low light conditions. Also, at longer wavelengths, NIRQuest+2.5 measures diffuse reflection at low noise levels, resulting in cleaner spectra at wavelengths where distinct spectral features can be difficult to capture.
NIRQuest+2.5 spectrometers are compatible with Ocean Insight's comprehensive line of fiber optic light sources, optical fibers and sampling accessories.
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
• Hydrocarbons 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
Quick tip: A spectrometer wavelength calibration source can be a useful tool for your lab. For NIR applications, we recommend an Argon (AR-2, 696-1704 nm) or Xenon (XE-2, 916-1984 nm) emission source.
