The high concentration of phospholipids (PLs) in blood serum is a frequent limitation in metabolomic analysis based on mass spectrometric detection, mainly owing to their ionization suppression effects.

Larger porous shell particles with narrow particle size distribution - used in reversed-phase U/HPLC analysis of peptides and proteins - provide increased efficiency per unit pressure drop, which can be taken advantage of by increasing peak capacity or traded in to reduce analysis time.

In this application, the use of SupelMIP SPE – Patulin is demonstrated for the cleanup of patulin in apple juice.

Nuts are considered nutrient dense foods and their consumption has been associated with reduced risk of coronary heart disease. The health benefits of nuts are partially attributable to their high content of unsaturated fatty acids.

In this study the impact of matrix interference is investigated with respect to precision and accuracy of antiarrhythmic cardiac drugs from plasma samples.

Chiral 2-hydroxyglutarates (2-OHG) are important molecular signatures of their specific biochemical pathways and inborn errors of metabolism, for both healthy and diseased biological cells

The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air.

Extraction of lipids as fatty acids and the subsequent detection of trans fats from a cookie sample, using Silver-Ion SPE fractionation followed by GC analysis on SP-2560 and SLB-IL111 columns

The amount of benzene in gasoline is a concern because it is a known human carcinogen, and exposure to it has been linked to detrimental health effects.
