The NIR 2.2 is a complete NIR spectrometer with a Peltier-cooled InGaAs diode array detector for the extended NIR range up to 2.2 m on a PC card. The spectrometer has no flexible or adjustable parts and is completely maintenance-free. This guarantees a high degree of stability of the prepared calibrations. High detector sensitivity and Peltier cooling of the InGaAs diode array also permit high speed measurements in the millisecond range.
Owing to the flexible fiber-optical coupling, the spectrometer can be used for various different applications in process analysis, mobile analysis or quality assurance. In connection with chemometric methods, it is well suited for quantitative as well as qualitative analysis. The spectrometers for the extended NIR range up to 2.2 µm are useful for transmission measurements as well as for reflection measurements.
In addition to the CDISPEC software that is included in delivery, a GRAMS®/32 package and a MyInstrument driver are available optionally. Using the driver the spectrometer can directly run under GRAMS®/32 software. This allows you to build your chemometric models for quantitative or qualitative analysis easily.
Should you have questions concerning the technical specification; our application scientists will be pleased to consult you.
