sample preparation headspace gas chromatography Chrominex

A hardwired connection is built into the remote start cable between the GC and the Headspace Sampler. Use this function to wait for the GC ready signal, abort the sequence, or proceed without the GC ready signal. If Check For Ready is active, then the sampler will check for the presence of a ready signal from the GC just prior to injection.

4 An Introduction to Headspace Sampling in Gas Chromatography Partition Coefficients The previous description is simplified. In practice, the migration of compounds into the headspace phase does not just depend on their volatility but more on their affinity for the

Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix.

Aijiren GC sample introduction systems increase the efficiency, performance, and flexibility of your gas chromatography systems. In addition to offering reliable and consistent injections from less than 1 µL to large volumes, GC autosamplers provide the ability to perform automated sample preparation procedures that range from simple dilutions to complicated derivatizations.

Headspace gas chromatography offers an efficient sample-preparation technique that can save both time and money in the analysis of VOCs in a number of matrices. Headspace sampling is a separation technique which allows for the extraction of headspace vapor from a sealed sample, with subsequent injection directly into a GC.

The autosampler is configured so that one rail is used for sample preparation and the other rail is used as a traditional autosampler for sample introduction into the gas chromatograph inlet. The sample preparation rail draws up and sequentially adds a saturated sodium chloride solution and internal standard (0.08%, w/v acetonitrile) to a headspace vial containing a biological sample, a
