Are your OOS investigations scientifically sound and is the assignable cause correct? Or are OOS results invalidated using the ever-popular justification of analyst error?

After a few months of the coronavirus shutdown, the author has found some effective approaches to teaching and holding research meetings remotely.

In this study, a method for extraction and preconcentration of trace amounts of organophosphorus pesticides was developed using magnetic solid-phase extraction followed by HPLC with UV detection.

In this interview, Rafael Paseiro-Cerrato of the U.S. Food and Drug Administration discusses his investigations into the potential for compounds in can coatings to migrate into food.

In gas chromatography, heating the sample in the inlet can lead to sample losses and loss of quantitative reproducibility, but these problems can be avoided using cold sample introduction. Here, we explain the various types of cold injection and why you should consider it in your next instrument purchase or upgrade.
