Sep 30, 2020 · Vials and Closures Chromatography vials and closures are commonly used in gas and liquid chromatography for sample analysis, collection, and storage. Vials are most often made of glass but can be plastic as well. Vial dimensions and physical specifications are crucial to trouble-free operation with autosamplers and other instrumentation.

Chromatography Vials. Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on patch, possible identification errors are eliminated.

Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Amber glass vials are available in 2-60 ml volume with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.

The Target DP 9mm screw thread closures from National, utilizing Advanced Vial Closure System (AVCS) technology, removes obstacles to highly reliable and efficient analysis of samples by offering a complete sample handling solution for chromatography applications in 12 x 32mm vials.

Headspace Vials & Closures Unlike crimp cap vials, Aijiren Tech National 18mm Screw Top Headspace Vials require no tools for closure. Manufactured with superior quality (Type 1, Class A) glass, they are available with a round bottom in sizes with usable volumes of 10mL or 20mL.

The objective was to develop a simple routine method for quantitative measurement of endogenous formic acid in plasma and whole blood using headspace gas chromatography-flame ionization detection. (GC-FID). Two-hundred microliters of sample was placed in a 1-mL glass vial. Fifty microliters of aqueo

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. 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

Dec 15, 2004 · A quantitative assay for the analysis of sesquiterpene synthases, wherein each reaction mixture is formulated in glass gas chromatography vials, overlaid with organic solvent such as ethyl acetate, and subsequently vortexed to extract hydrocarbon reaction products into the organic phase after a suitable incubation period, was developed.

Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on patch, possible identification errors are eliminated.

Chromatography Vials & Accessories. Chrom Tech offers a large portfolio of chromatography vials for use with most autosamplers for Mass Spectrometry, GC, and HPLC applications. Vials are very commonly used in chromatography as single-operation handling containers that can be made of glass or plastic with a variety of closure options.
