Principle & Features

The airmoVOC WMS uses a valve with a sample trap and a metallic capillary column. Its main features include: miniaturization, sensitivity, mobility, and flexibility. Everything from the sample port to the data storage is integrated into a wall-mounted box. It offers uninterrupted sampling with pre-concentration on an absorbent tube and a gas chromatograph with a metallic column with a programmable temperature gradient oven. Pressure control of the carrier gas is managed by a piezo-valve and each unit is tested for one week after production for quality control.

Software

Vistachrom software enables visualization and storage of data on a PC, including tools for recalculating, calibrating, exporting data, and setting up measurements. The software allows calculation of retention time, area, mass, or concentration profiles.
