► 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.
