AutoGCMS is a combination of two robust and miniaturised instruments, airmoVOC and/or ChromaFID and Det QMS, which allows quantification and identification of chemicals from high ppm to low ppt levels (depend on autoGC configuration) for VOCs, organosilane, odorants compounds. AutoGCMS integrate gas generators and calibration system for operation without any cylinder (in compliance with ISO 17025 for Benzene).

The analyzer is tested more than two weeks in our quality control department and then delivered and installed by our engineers. Once the instrument is set and running, the operators can easily control the air quality.

Vistachrom and Vista MS software enable users to view and store data on an industrial computer. It provides user friendly utilities to recalculate, calibrate and export data and to configure the measurement.
