Biological Sample Preparation using the Protein Precipitation Plate P3

Biological samples commonly contain proteins that interfere with downstream applications. The P3 plate uses the CRASH method, in which the protein is denatured with acetonitrile and the flocculant filtered out, allowing 96 samples to be handled at one time. The Protein Precipitation Plate, P3, is based on the industry standard MicroLute™ format, but without the chromatographic sorbent. Protein ‘crashes’ out of solution and precipitates directly in each well when acetonitrile is added, thus solving all […]

SiliaQuick™ QuEChERS: the Simple way

QuEChERS (Quick–Easy–Cheap–Effective–Rugged–Safe) is a highly beneficial sample preparation technique for multi-residue pesticide analysis: makes it simpler, cheaper and quicker for the analytical chemist.

Since the publication of the original method in 2003, the QuEChERS method has gained in popularity to become the most valuable alternative in pesticide residue analysis worldwide. The approach as spread to multiple organic compounds, including pesticides, herbicides, fungicides antibiotics from a vast array of food matrices.

The QuEChERS procedure requires a minimal number of simple steps, […]
