The global demand for fish as a natural source of fresh animal protein, essential fats, minerals, and vitamins continues to rise with the human population.

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.

Diesel range organic (DRO) compounds have boiling points similar to diesel fuel (C10–C28), ranging from 170–430 ?C. These heavy compounds are amenable to GC-FID analysis; however, important considerations should be taken to ensure reproducible results over repeated injections.

Heterocyclic amines (HCAs) are a class of compounds that are formed when amino acids from meat proteins react with glucose and creatine under high-temperatures, as is associated with frying or grilling over an open flame (1–3). Studies have correlated the consumption of high levels of HCAs with an increased risk of some forms of cancer.

When working with complex matrices such as personal care products, sample preparation is perhaps the most difficult step of the analysis process. By utilizing a targeted sample preparation technique, such as ion-exchange SPE, analysis can be significantly improved as compared to less targeted techniques such as liquid-liquid extraction.
