ChromaPID - BTEX Analyzer with PID Detector
FromChromatotec
A GC PID for automatic monitoring of compounds, in air, water or soils: This instrument uses a port valve with a loop, and a metallic 0.53 mm ID column. It has a minimum detection level of ppb. 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. Isothermal oven in standard (programmed gradient temperature in option) : pressure/flow control of the carrier gas by the-valve.
