GasRaman NOCH-1 High Performance


GasRaman NOCH-1 High Performance is discontinued.


Product Details

The GasRaman NOCH-1 gas phase process Raman analyzer instrument features a diode-pumped solid state (DPSS) laser. 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 spectroscopy system provides fast and accurate laboratory and online gas phase Raman analysis, with no extractive sampling required.
