Sample Vials

Standard crimp top or screw cap vials, 20 mL , 10 mL . No adaptor required for 10-mL sample vials.

Mode of Operation

Shaking with choice of off, low, or high.

Constant heating time (CHT) mode for each sample. Overlapping up to 12 vials for maximized sample throughput

Multiple headspace extraction (MHE) mode with up to 100 extractions per vial for method development and validation or for analysis of sample in unusual matrices

Multiple headspace extraction concentration (MHC) mode , with up to 10 extractions from 1 vial made followed by one GC start after the last extraction to increase sensitivity

Pneumatic Control

In-unit switch connection between:

Built-in manual pneumatics (pressure regulator and flow controller) and GC built-in electronic pneumatic control (EPC)

Interfacing with GC

Volatile inlet (VI) or other standard GC inlet

Communication

LAN; RS-232; Remote start/stop

System Control

Control and monitoring by full function control keypad and built-in multiline display. Features:

•            Parameter set up

•            Store up to four user defined headspace methods (there are also five preset methods)

•            Detailed power-on self test

•            Built-in leak test routine

•            Update firmware via LAN or RS-232

•            Monitor set and actual values, as well as, operation status

GC ChemStation

Complete integration/control with the GC ChemStation , (G2070AA - A.09.03 or later) and headspace control SW (G2922AA). Headspace parameters are part of a GC method. Using a GC ChemStation sequence table to track sample from sampling to analysis. Event log function records every step of headspace events. FDA 21 CFR part 11 compliant. (Must also order ChemStation Plus Security Pack separately.)
