Methods: Vials and closures were exposed to acetonitrile for 2 hours and subsequently analysed by LC/UV, LC/MS and GC/MS to characterise the interferences. Comparisons were made between pre-cleaned MS Certified vials and closures, a control and a competitor vial and closure set. Introduction

Using poor-quality vials (or the wrong vials for your application) can cause sequence problems, unnecessary downtime, expensive repairs, and the loss of precious samples Aijiren vials are the only vials that deliver time and cost savings: • Reduced labor: Our short-thread screw-top vials make screwing/ unscrewing the cap up to 30% faster.

For use on GC Headspace Vials or LC Large Volume Vials. Crimp capping is still a preferred method by some laboratories to ensure sample integrity, particularly those containing volatile compounds. Related Products: 20mm Vial Crimper

Our portfolio consists of GC vials and LC vials, GC caps and LC caps, and GC septa and LC septa. Through our biological line, we offer glass and plastic vials for optimal measurement of samples by liquid scintillation counting. Our glass vials are chemically-inert, making them suitable for use with aggressive reagents and solubilizers.

One disadvantage of crimp seal vials is the variation in the depth of the vial opening lip, which is the location of the seal. Septa thickness varies as well; therefore, to reduce or eliminate problems with making a proper seal, use an adjustable crimper.

Gas chromatography (GC) is a powerful tool in the analysis of alcoholic beverage prod- ucts. Minimal sample preparation, in general, is required, since the samples are in the liq- uid state in an alcohol or alcohol/water matrix. The flavor compounds tend to be volatile in nature, which fulfills one of the main requirements of GC.
