This application note presents thermal extraction of phthalates in accordance with IEC Method 62321-8 using a 6150 Pyroprobe.

Metal-free columns should be considered when troubleshooting ion suppression. Chelating compounds that can form metal salt with stainless steel column housings are examined.

We recently introduced a new series of UHPLC columns with a particle size of 1.6 µm. Here we explain how to transfer an existing HPLC method to a new UHPLC method using polyphenols as an example.

Potency testing in marijuana-infused edibles is a problematic task due to the complexity of the matrices. The concentration of active ingredients in edibles can range from a few ppm to 3.5% (1). In this application, active cannabinoid compounds were extracted from gummy bears (and also brownies, results not shown), followed by HPLC analysis.

The European Pharmacopoeia (Ph. Eur.) defi nes requirements for the qualitative and quantitative composition of medicines, as well as the tests to be carried out on medicines and on substances and materials used in their production.
