Extraction and Analysis of Acrylamide from Coffee
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.
A Well-Written Analytical Procedure for Regulated HPLC Testing
October 15th 2024This paper describes the content of a well-written analytical procedure for regulated high-performance liquid chromatography (HPLC) testing. A stability-indicating HPLC assay for a drug product illustrates the required components for regulatory compliance, including additional parameters to expedite a laboratory analyst’s execution.
