Why are Crimp Top Vials Used in Chromatography? 5 Reasons

Nov. 15th, 2023
Chromatography is an invaluable analytical technique used across numerous scientific disciplines, such as chemistry, biochemistry and environmental science. This form of analysis allows scientists to separate, identify and quantify individual components in mixtures. Crucial for any chromatographic analysis is the sample vial; among all available options available to them crimp top vials have gained great traction among them all; in this article we'll examine why they are popularly chosen.

1.Seal Integrity:

Crimp top vials feature flat, polished surfaces and narrow necks designed to form an effective seal when combined with a crimp cap, providing tight protection from evaporation or contamination of samples. Seal integrity is especially essential when conducting gas chromatography analyses, where volatile compounds may easily evaporate if vials aren't sealed adequately.

2.Reduced Contamination:

Crimp top vials' narrow neck minimizes exposure of samples to external environments, making chromatography much more accurate and reproducible as even trace amounts of contaminants can seriously impair results. By decreasing contamination risk, crimp top vials contribute towards producing reliable and reproducible data sets for analysis.

3.Compatibility with Autosamplers:

Automated chromatography systems often utilize autosamplers to handle multiple samples efficiently, and crimp top vials are an ideal fit with these autosamplers as their crimp caps can easily and consistently seal using automated crimping tools - simplifying sample preparation process while improving overall efficiency of chromatographic analyses.

5.Economic Considerations:

Crimp top vials can often be more cost-effective than alternative sealing methods, making them an appealing solution for laboratories operating with tight budgets. Their simple crimping process and wide usage contribute to their affordability; this allows researchers to conduct high-quality analyses without breaking their finances.

Within chromatography, selecting an appropriate sample vial can have a considerable effect on the reliability and accuracy of analytical results. Crimp top vials have become popular due to their excellent seal integrity, reduced contamination risk, compatibility with autosamplers, versatility and cost-effectiveness - qualities which remain indispensable in creating accurate, reproducible analytical data. As techniques advance further still, their role remains essential in providing optimal sample containment and integrity that leads to precise analytical data.
