This paper describes a new modular concept that instrument manufacturer has undertaken to integrate latest valve technology, into a handling, plug-in module, full incorporating heating control of the valve, miniaturized pneumatic circuits for carrier gas supply and split as well as valve backflush to the vent. This modular design allows a new level of instrument flexibility, where inlets and/or detectors selection is based on the application in use, and can be changed in a matter of few minutes by the operator when a new analytical need or application requires different injector and/or detectors.
On top of improved technical performance in terms of injection repeatability and stability, this work shows the simplicity and flexibility in configuration setting provided by this Instant Connect modular design.
Without further hardware complexity the gas sampling valve module can be set to back flush to vent undesired part of sample, therefore offering an easy and integrated set-up for more complex analysis. Data showing performance of this solution are illustrated and discussed.
