Application Note: How to Avoid Contamination in Pipetting
Preventing contamination in pipetting is paramount to achieving reliable results. It requires identification of the potential contamination mechanism in order that they can all be addressed. This paper addresses the three contamination types that originate from pipetting: Pipette-to-sample contamination, sample-to-pipette contamination, and sample-to-sample contamination. Keep in mind: If your testing procedure in your Cannabis environment requires you to repeatedly portion out exact volumes of liquids involved, our bottle-top dispensers will give you a steady hand to ensure accurate and consistent results.
Determination of Terpenes in Cannabis by GC-FID (using 8300 GC / 8500 GC)
June 14th 2024Hemp and marijuana are becoming more popular because of legalisation in multiple countries. The increase of this market also increases the offer of products and therefore the need to monitor different components. One of these components are cannabinoids or just short potency analysis, which can be found in our portfolio of Cannabis applications (AN091,92,93,130). This application focusses on terpenes analysis.
Cannabis Potency Analysis by HPLC (June 2024)
June 14th 2024CBDV, CBGA, THC-A and CBDA cannot be detected with FID or MS without extra sample preparation due to decarboxylation caused by the heat of the injector. The HPLC is a perfect instrument to measure these components since it does not use heat for the injection. Discover the advantage of this technique being able to analyse acidic cannabinoids without the lengthy sample preparation seen in GC methods.
