Ethephon analysis usually requires indirect and laborious method including a derivatization step before gas chromatography tandem mass spectrometry (GC-MS/MS) determination. In this paper, the described method is quick and based on simple procedure without any clean-up. After addition of ethephon D4 as surrogate, a methanolic extraction was performed. The determination is done by high performance liquid chromatography coupled to a tandem mass spectrometer (LC-MS/MS) in electrospray negative mode. The chromatographic separation was achieved on a hydrophilic interaction liquid chromatography …
