Analysis of glucocorticosteroids by atmospheric pressure chemical ionization-liquid chromatography mass spectrometry (APCI-C/MS/MS)

Determination of valproic acid in serum by liquid chromatography-atmospheric pressure chemical ionization mass spectrometry.

Characterization of typical chemical background interferences in atmospheric pressure ionization liquid chromatography-mass spectrometry.

The structures and origins of typical chemical background noise ions in positive atmospheric pressure ionization liquid chromatography/mass spectrometry (API LC/MS) are investigated and summarized in this study. This was done by classifying chemical background ions using precursor and product ion scans on most abundant background ions to draw a family tree of the commonly occurring chemical bac...

Direct analysis of plasticizers in aqueous samples by atmospheric pressure chemical ionization-tandem mass spectrometry (APCI-MS-MS).

The use of liquid chromatography-atmospheric pressure ionization-mass spectrometry in water analysis ^ Part I: Achievements

Liquid chromatography-mass spectrometry using atmospheric pressure ionization is dramatically changing the analytical methods, potential and tasks of water analysis. The present status in applying this technique to organic as well as inorganic water constituents and its use in the context of wastewater treatment and drinking water preparation is reviewed. Separation techniques such as reversed-...

Analysis of very long chain polyunsaturated fatty acids using high-performance liquid chromatography - atmospheric pressure chemical ionization mass spectrometry.

The presence and identity of very long chain polyunsaturated fatty acids from three freshwater crustacean species, Bathynella natans, B. baicalensis and Baicalobathynella magna from Lake Baikal and caves of central Europe were determined by means of liquid chromatography-mass spectrometry with atmospheric pressure chemical ionization (LC-MS with APCI). LC-MS with APCI enabled the identification...
