Modern chromatography liquid autosamplers accept different sizes of vials. So the one you choose should be compatible with your autosampler. You can get a suitable vial from an EPA VOA Vials supplier. They can help you choose the right vial to perform your analysis.
However, choosing the best chromatography vial for your analysis can still be challenging. To make it easier, we’ve outlined some simple steps to select the best chromatography vial for your analysis. Let’s dive right in.
Identify the Closure Style of the Vial
Ensure you know the closure style of the vial. For example, screw thread vials are used for HPLC and LCMS analysis. These vials don’t require extra tools for attaching the cap and not even for removing the cap. At the same time, snap top vials are convenient for lab technicians, so they are preferred over screw thread vials. Crimp vials are other types used as GC vials for gas chromatography vials. So you must know which type of vial closure style it is.
Identify Vial Material
The most common type of autosampler vial is Type 1 Borosilicate glass, representing the least reactive glass. This type of glass has the least PH shift with a coefficient of expansion of 33 or more. At the same time, plastic autosampler vials are economical when you require a little volume vial. These types of vials are commonly Polypropylene (PP) and are compatible with Acetone, Methanol, Isobutyl alcohol, methanol and methyl ethyl ketone.
Know the Volume of Vial
When you have a limited amount of sample, you can use an autosampler vial with a compatible vial insert(of small volume). Vial inserts come in tapered inserts that hold the maximum amount of sample and enable maximum sample recovery because of the taper. There are several flat-bottom inserts available which are an economical option that hold a considerable sample volume. Majorly, high recovering chromatography vials if you want to re-inject the sample multiple times.
Know the Sizes of Vials
Standard vial sizes of chromatography vials are 20 ml, 40 ml, and 60 ml. However, if you’re using an autosampler, choose a vial that’s designated for that particular brand. They are used for smaller samples to make sure the proper amount of sample is aspirated from the vial.
