This instrument uses a 6-port valve with a single sorbent trap, and a metallic capillary column.
It has a minimum detection level of as low as 0.5 ppb in ambient air.
The airmo H-CHO uses a thermoelectric cooling system to control the temperature of the sample trap when required, for example for the analysis of Formaldehyde.
Formaldehyde and acetaldehyde react with a catalyst for more sensitivity with FID.
Miniaturization, sensitivity, mobility and flexibility are its main features. Everything from the sample port up to the data storage is integrated in a 19"-rack 4U.
Programmed gradient temperature of the oven and pressure/flow control of the carrier gas by the piezo-valve.
Before final delivery the analyser is tested for three weeks by the quality control department.
The Vistachrom software enables the user to view and store data on an industrial computer. It provides comfortable user friendly utilities to recalculate, calibrate and export data and to configure the measurement. The software allows the calculation of retention time, area, mass or concentration profiles.Calib is a very important option for good result in ppb range.
We use permeation tubes for calibration.
