Adsorption can Happen Quickly in an Autosampler Vial. Tips & Suggestions

Adsorption in Borosilicate Glass Vials is Time Dependent. But can be Fast. We have shown from previous experiments of how concentration of certain analytes can be adsorbed to glass surfaces over time which is an indicator of potential problems for the laboratory for many other analytes as well. In this experiment, a sample was taken […]

Are the Soft-Guard™ Septa and caps compatible with LCMS or LCMS/MS?

Yes. The Soft-Guard™ Septa will outperform most septa and caps on the market when used with most LCMS applications. For very sensitive LCMS/MS applications we recommend our Advanced Quality, AQR™ septa and caps which is colorless, ultra-pure and designed for the most critical chromatography applications. The AQR™ cap incorporates all the benefits of the Soft-Guard […]

How to Achieve Best Practices for Crimping a Cap on a Vial.

It is important to understand that crimping a cap could result in an inadequate seal if not done properly. Follow the steps shown below to achieve the best seal. You need a calibrated crimping tool (https://mtc-usa.com/Crimping-Tool) This means that the chuck has to be adjusted every 10 -15 crimps with the adjusting tool it comes with. […]

What is the useable Volume in 2mL Autosampler Vials? – FAQ

A vial that is listed as 2mL is defined as the entire fill volume, with no headspace when the cap is secured.  In practice though, a sample solution cannot contain this much volume because of displacement caused by the syringe needle during injection causing the autosampler to inaccurately withdraw the solution. For this reason, a […]
