Beside liquid injections, the GC PAL can sample up to 500 µL of the ambient headspace in 2 mL/10 mL vial. This straightforward and inex-pensive procedure serves as a quick screening tool for unknown volatile samples. Variable syringe needle depths enable sample aspiration anywhere within a sample vial. Two layers of

Static headspace GC (SH-GC) is a commonly used technique in the analysis of these OVIs. This technique concentrates volatile analytes, and allows for their analysis free from sample matrix. Samples to be analyzed by SH-GC must be dissolved in a suitable solvent; and in addition to being able to dissolve the sample, the solvent chosen must allow

For specific analysis, the sample volume is also related to the volume of the vial. The upper limit of the sample volume is 80% of the volume of the vial so that there is sufficient headspace for sampling. A sample volume of 50% of the vial volume is often used. Sometimes only a few microliters of sample are used. The nature of the sample, the purpose and method of analysis are the main factors determining the volume of the sample hplc vials manufacturer in china.

18mm Headspace Vial use for Autosampler. The function of the headspace bottle produced by Aijiren is to store volatile samples to prevent the sample from evaporating. The headspace bottle itself is resistant to high temperature and corrosion, and is mainly used for headspace analysis in gas chromatography.

Oct 22, 1999 · DMF which was used to extract the patches and to make the standards was rendered free from trace level contaminants by purging with nitrogen gas for 2 h at a flow-rate of 5 ml/min. Thirty ml capacity headspace glass vials, septa and aluminium closures were all obtained from Hewlett-Packard (Wilmington, DE, USA).

Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including autosampler vials, general-purpose vials, and vial accessories for sample collection, storage, and

Headspace Sample Size In addition to working with K, β, and derivatization reactions, sensitivity also can be improved by simply increasing the size of the headspace sample that is withdrawn from the sample vial and transferred to the GC. Increasing the sample size also means that the amount of time it takes to transfer the sample to the
