You don’t have to work as a scientist to know that the evolving field of chromatography is keeping us alive. Technicians are in the lab every day, ensuring they meet food quality standards while developing new pharmaceuticals. Chromatography is a lab technique used to separate mixtures for analysis. Solvents are sent through mobile and stationary phases to help scientists determine the identity of their components. Knowing how to select the best chromatography vials makes the process more efficient.
Choose Good Quality Vials
The best way to ensure you are getting good quality vials is to check the rating from the company from which you purchase time. Vials should be clean so that you don’t experience cross-contamination. You can validate the process by which the vials are made by reading the manufacturer’s website or giving them a call.
Chromatography Vial Materials
Most chromatography vials are either glass or plastic. Glass is often preferred because it doesn’t contaminate and is heat resistant. Plastic is popular because it is budget-friendly and less likely to break. Polypropylene and polymethyl pentene (PMP) are the two types of plastic vials; PMP is slightly better due to its translucent quality.
Pro Tip: Consider the color of the vial when choosing as well. Some are clear, while others come in an amber shade.
Consider Your Sample Size
The size of your vials is as important as their quality. If they aren’t big enough to contain your sample, they aren’t useful. Consider the size of the samples you’ll use and choose vials that can withstand the capacity.
Pick the Proper Cap
Part of the anatomy of a vial is the closure. You’ll need a cap and septa to help prevent contamination between samples during storage. Knowing how to choose the right headspace vial cap is essential when building vials for chromatography. Headspace caps are ideal for high-pressure situations.
You’ll get better results when you know how to select the best chromatography vials for your experiment. You have fewer chances for contamination with better-quality vials. Further, choose vials that are the right size and material for your needs to save time and money.
