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.
► Before final delivery the analyser is tested for one week by the quality control department.
► Photo ionisation detector (PID), 10,6 eV lamp in standard.
► Other lamps on request.
► Self-cleaning of the lamp for high stability.
► 0….1 V analogue output (contact) for the purpose of low or high alarms on the concentrations of the analysed compounds.
► Bi-directionnal RS-232 to transfer data and results to the computer.
► The Vistachrom software enables the user to view and store data on a PC. 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, in any international measuring unit.
