15 صفحه اولReduction of Ionization Suppression in Water Samples when Using LC-ESI-MS in Negative Ion Mode
Experimental modifications that inhibited ionization suppression when using LC-ESI-MS (liquid chromatographyelectrospray ionization-mass spectrometry) in negative ion mode are described for two classes of materials: steroid estrogens and acidic herbicides. Introduction Ionization suppression is a problem when using electrospray ionization (ESI) in negative ion mode. It leads to an apparent redu...
متن کاملEffect of Sample Matrix on Suppression of Ionization in Water Samples Using LC-ESI-MS Application
Liquid chromatography electrospray ionization mass spectrometry is a very powerful technique that combines the liquid chromatography separation with highly selective and sensitive mass detection, but the ionization process is susceptible to matrix signal suppression. Signal suppression, therefore, presents a challenge in doing quantitative liquid chromatography/mass spectrometry applications. U...
متن کاملDetermination of 13 Free Fatty Acids in Pheretima Using Ultra-Performance LC-ESI-MS
A simple and rapid ultra-performance liquid chromatography-electrospray ionization mass spectrometry method for the simultaneous determination of thirteen free fatty acids (FFAs) in Pheretima has been developed and validated. Measurements for each FFA were linear over a wide range (0.05–3.95 μg mL) with good correlation coefficients (>0.99). The limit of detection and limit of quantification fo...
