Vacuum techniques from multigas 2030 is ftir based on line gas analyser from mks instruments, online product division. This is capable of ppb to ppm sensitivity for multiple gas species in variety of application. The multigas 2030 can perform analysis in gas streams that contain up to 30% water and can simultaneously analyse and display more than 30 gases with permanently stored calibration spectra, the need for costly gas cylinder is reduced. In addition, operators will find the robust fully automated multigas 2030 easy to operate and maintain. Application in stack monitoring [environmental compliance], process monitoring, development and optimisation, ambient air analysis [industrial hygiene], bulk gas purity analysis, etc.
