ARI Gas Chromatograph

A field-deployable GC with in-situ preconcentration for time-of-flight mass spectrometry (TOF-MS)

GC Technology

• Aerodyne Research, Inc. (ARI) offers a modular gas chromatograph (GC) that combines recent innovations in fast GC separation with highly selective and sensitive detection in a field-deployable package for the measurement of VOCs and OVOCs.

Aerodyne works with our customers to provide a GC system with a custom separation method appropriate for their analytical needs. The instrument delivers with the required capillary column installed and analytical methods pre-loaded into the Windows-based control software, for a true turn-key operation.

Features

Flexibility – user selected number of GC columns, preconcentration methods (e.g. thermal desorption vs cryo-mechanical), detector type(s)

Vocus compatible – true plug-and-play operation with the ARI Vocus PTR-ToF-MS (hardware and software)

Dual detectors – designed to operate automatically with two detectors for a more complete data set

Turn-Key – delivered with custom pre-loaded method(s) developed and demonstrated based upon user requests

Field-deployable – the ruggedized GC has a maximum power consumption is 300 W during normal operation, with a benchtop footprint of 55 x 30 cm

Speed – flow path allows user to perform multiple GC operations at once; the benefit of this parallel operation is a faster GC cycle (10 – 30 min) without loss of performance

Data Analysis Software

• Wavemetrics Igor Pro analysis software (TERN) allows for retention time correction, automated baseline and peak fitting. TERN provides de-convoluted peak fitting for overlapping chromatographic peaks, and is open-source code for user modification or expansion.
