LCGC North America

Using oral fluid as the matrix, a viable and simple solid phase extraction method for a wide range of drugs is developed. Several oral fluid collection devices were evaluated to determine the effectiveness of the cleanup procedure, ultimately confirming that the method is both robust and widely applicable.

Cooking at high temperatures causes a chemical reaction between certain sugars and asparagine which causes acrylamide formation. In this technical note, we explore how to use Novum™ SLE tubes to clean up a coffee matrix in order to quantitate known acrylamide levels. The recovery is especially significant when you consider the polar nature of the acrylamide (LogP -0.27). In addition to high recoveries (>90 %), the low values for the standard deviation and %CV indicates method reproducibility.
