(maximum temperature software limited to be no greater than the limit for the columns installed, isothermal operation is available). Column
modules are 2 meter columns in Mxt-1, Mxt-5, Mxt-1701, Mxt-Wax, Mxt-MoleSieve, Mxt-Alumina, < 320µm and various film thicknesses with
others coming soon.
Flame ionization or thermal conductivity (filament) detection
Gas and liquid inlet for syringe injection of samples or automated gas and liquid sample valves available
Performance
(application dependent)
Repeatability of ± 1% RSD or better (area) and of ± 0.1% RSD or better (retention times)
Analysis times for VOCs: can be <20 seconds and for SVOCs: can be <60 seconds
Dynamic range: depends on detector used and application (FID typically 10

)
Data Processing and Instrument Control
Note: computer system is integral and necessary component of the analysis system and includes the following:
RS-232 or USB to RS-232 adapter, ethernet
Windows XP or newer operating environment
ChromPerfect software for dual column data acquisition via RS-232 serial or ethernet ports
