Analytical chemistry technique with on-line coupling of liquid chromatography to mass spectrometry.
1
Phospholipids were extracted from the four tissues and blood and analysed by HPLC-MS.
2
Subsequent HPLC-MS and NMR analyses resulted in the identification of 1-acetyl-β-carboline as active component.
3
Pyrimethanil was confirmed by high-performance liquid chromatography-mass spectrometry HPLC-MS in the selected ion monitoring mode.
4
SHLI with removal forsythoside A with the technology of HPLC-MS displayed reduced pseudoallergic reaction and a significant improved safety.
5
Five graft-inoculated trees of each variety and three control trees were sampled biweekly and analyzed by HPLC-MS and PCR.
