Does your work involve developing gas-phase monitoring processes? Consider the GasRaman NOCH-1 Sytem from TSI. The NOCH-1 analyzes gases faster, more easily, and with lower maintenance than traditional techniques like Gas Chromatography (GC). The NOCH-1 gas phase process analyzer accurately identifies and quantifies gases with excellent sensitivity, but without the hassle or price tag associated with alternative methods. The GasRaman NOCH-1 Analyzer, coupled with our flexible software, truly makes our system ideal for process development.

Product Details

The GasRaman NOCH-1 gas phase process Raman analyzer instrument features a diode-pumped solid state (DPSS) laser operating at 532 nm.  The spectrometer has a spectral range of 250-4200 cm-1, and the detector is cooled to minimize dark current. The resolution of the system is about 8 cm-1. The graphic user interface of the control and data acquisition program includes a time trend and ratio calculate in a time chart mode to enable spectral changes with time to be observed.  

The NOCH-1 GasRaman system provides fast and accurate laboratory and online gas phase Raman analysis, with no extractive sampling required.
