App Notes

This Application Note describes the performance of a sorbent tube and optimised analytical protocol dedicated to the detection of ppt-level polycyclic aromatic hydrocarbons (PAHs) in ambient air.

Sprayed Polyurethane foam (SPF) insulation is widely used in construction and for renovation and thermal insulation of existing buildings.

Brad Meadows is Vice President and Laboratory Director at the US company BSK Labs, which runs a number of environmental laboratories.

Raptor™ C18 SPP 5 μm core-shell silica particle columns offer excellent resolution for fluorochemicals with short total cycle times. For even faster analysis, 2.7 μm core-shell particles are available.

Linalool is a component of many essential oils. Popular spices, such as cinnamon, ginger, basil and black pepper contain linalool. Due to its fresh and flowery fragrance, linalool is used for both fragrance and flavour. With CHIRAL ART Amylose-SA a baseline separation is achieved in less than 6 minutes!

Blood plasma and serum are the most common sample types in routine diagnostics as well as for biomarker discovery. Targeted proteomics, a mass spectrometry based method, allows absolute quantification of more than 100 proteins per sample analyzed in a high-throughput mode.

Chromate (Cr(VI)) is considered toxic and potentially carcinogenic for which reason its concentrations in consumer products such as toys should be as low as possible.

The speciation of trivalent – Cr(III) – and hexavalent – Cr(VI) – chromium is important due to the toxic nature of the latter.

Soil usually contains small amounts of chromium that stem from weathering rocks or anthropogenic sources.

Hexavalent chromium (chromate) is considered toxic and potentially carcinogenic for which reason its concentration in environmental and drinking water should be as low as possible.
