Identifying odor-active compounds in acrylic paints

Acrylic-based paints are among the most frequently used by artists. Although they can be produced on a water basis and with low levels of volatile substances, they often still possess a strong inherent smell. However, no targeted studies have as yet been conducted to identify odor-active ...

ICH Linearity Studies using Automated Standard Preparation and UHPLC

According to the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), it is necessary to test analytical methods for their linearity as part of a method validation study. The typical process for this is to prepare standards ...
