Comprehensive two dimensional-gas chromatography t

The Environmental Protection Agency (EPA) is seeking sources for a comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-TOFMS) system. The system should include an autosampler, cryogen-free thermal or flow modulator, computer, and associated software for instrument control, data acquisition, data processing, and reporting. • The system must be capable of performing comprehensive two-dimensional gas chromatography time-of-flight mass spectrometry. • The system should include an autosampler for automated sample injection. • The system must have a cryogen-free thermal or flow modulator for temperature control. • The system should include a computer and associated software for instrument control, data acquisition, data processing, and reporting.
