An optimal crimp result is characterized by the following features: The cap surface is flat. The sides of the cap fit tightly around the vial neck and do not show any deformations. The septa is not being sucked into the vial nor does it
Investigation by gas chromatography-mass spectrometry of potential contamination incurred by the use of crimp-cap vial closures S. J. Pattinson and J. P. G. Wilkins, Analyst , 1989, 114 , 429
These chromatography vials are designed and engineered for trouble-free operation in most autosamplers, to give optimum performance with HPLC and LC/MS applications. These 4ml Snap top vials that are nearly contaminant free, used in compound storage as well as for chromatography
2021/04/08 · Crimp Vials are commonly used as a GC Vial for gas chromatography analysis. Crimp Vials are the gold standard when concerned with sample evaporation. Crimp Vials are also required when chain-of-custody or tamper-proof closures are required. When using crimp vials, we recommend the electronic vial crimper for ergonomic crimping of your GC vials.
When separating organic and inorganic compounds for analysis, chromatography vial closures protect compound mixtures from contamination. The caps feature different finishes and septa materials for gas or high performance liquid chromatography applications. Maintain a clean and safe workplace using the spill-free chromatography vial closures
