Ultra-accurate, highly versatile trace gas analyzer configurable to a wide range of applications




Sensing Technology


The Chroma trace analyzer is one of the most versatile gas monitoring solutions on the market. Utilizing a unique, non-depleting plasma emission detector, the Chroma is a mainframe customized to your application.

Offering multi-component trace measurement at ppb, ppm or % level, the Chroma can monitor H2, O2, N2, Ar, CH4, CO, COand NMHC impurities in H2, O2, N2, Ar and He. Optimized via a sophisticated and flexible operational software that offers access to all device functions via a PC, the Chroma is configurable for a wide range of complex applications including medical gas purity, air separation, argon recovery, hydrogen purification and semiconductor wafer manufacture. 

With a range of sophisticated sensor options supported by PlasmaHC and ArgonSep technology for the measurement of NMHC/methane and separation of argon respectively, many applications will be satisfied by a single 4U rack analyzer configuration: all helping to make the SERVOPRO Chroma one of the most compact and powerful trace analyzers available.
