App Notes

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.

This Application Note shows the simultaneous determination of As(III) (arsenite), As(V) (arsenate), Se(IV) (selenite), and Se(VI) (selenate).

The speciation analysis of iron is crucial because the oxidation state determines the environmental behavior.

This application note describes the use of ISOLUTE® ENV+ on-line cartridges in a fully automated on-line SPE-LC-MS/MS method for extraction and quantification of 16 acid herbicides in drinking and surface water.

This free whitepaper describes a method for the straightforward determination of the herbicide glyphosate and its primary metabolite AMPA in drinking water by ion chromatography.

HPLC techniques can be hyphenated with GPC/SEC in a fully automated setup to deformulate copolymers and analyze heterogeneous components regarding their chemical composition and molar mass distribution.

According to this research, PECVD plasma monitoring using spectroscopic OES (Optical Emission Spectroscopy) and other complementary methods provides for rich information which helps to control and optimize thin film deposition processes.

AZURA® Analytical HPLC and UHPLC systems are designed to support and facilitate your work. AZURA systems are the right tool to overcome your analytical challenges.

The efficiency of luminescence is usually quantified by the emission quantum yield (QY), which is defined as the number of emitted photons divided by the number of absorbed photons.
