How to Choose the HPLC Sample Vial for Chromatography ? 1
Jun. 3rd, 2020
For many users of HPLC Sample Vial, the HPLC Sample Vial is only a temporary container for keeping the sample until it can be analysed by gas chromatography (GC) or liquid chromatography (LC). However, choosing the right vial and its proper use will go a long way forward by ensuring that the results of the sample analyses are as accurate as possible. Here are some tips for choosing the best HPLC Sample Vial for your chromatography needs.
Identify vial types
The HPLC Sample Vial is available and it is important to be able to distinguish them by size and closure. The vials are of different sizes, the most common in liquid injections are vial of 12 x 32 mm. Depending on the manufacturer of the vial, 12 x 32 mm vials can also be called a 1.5 ml or 2.0 ml vial. The HPLC Sample Vial also has various closures, including crimp/snap or screw closures. Screw-type closures are also of different sizes, which is identified by the outer diameter of the mouth of the vial. Screw-type closures for chromatography vials are either 8 mm, 9 mm or 10 mm, 9 mm is the most popular size.
Choose the right vial
If you are using an autosampler, be sure to choose a HPLC Sample Vial designed to work for your specific instrument brand. For example, the 11mm crimp and 9mm screw cap vials work with the Agilent autosampler, but the 10mm and 8mm screw caps do not work. This is due to the fact that the condition between the vial cap and the vial shoulder necessary for the correct functioning of the automatic probe varies according to the instrument.
In addition to the equipment requirements, you should also consider how the color and material of the vial can affect the sample. If the sample is sensitive to light, use a amber HPLC Sample Vial. If you need to look at the color change (e.g. quechers), a clear HPLC Sample Vial is the best choice. Lastly, if the analysis includes IC or ion chromatography, avoid glass vials/vial inclinations and choose a vial of polymer material to avoid ions leaching out of the glass.
