Problems in Analyzing Trinexapac-ethyla New Plant Growth Regulator

A method for the determination of trinexapac-ethyl had proposed the use of HPLC with three-column switching. An unproved method, taking advantage of SPE cleanup and GC/MS for analyses, is described. Analyses of wheat and rape were used as experiments to evaluate the method. Rapid decomposition of tr...

Beschreibung
Zusammenfassung:	A method for the determination of trinexapac-ethyl had proposed the use of HPLC with three-column switching. An unproved method, taking advantage of SPE cleanup and GC/MS for analyses, is described. Analyses of wheat and rape were used as experiments to evaluate the method. Rapid decomposition of trinexapac-ethyl was stated and must be confirmed. Therefore, spiked extract had to be used to determine the detection limit of the GC/MS method. Keywords: Plant growth regulator; trinexapac-ethyl; GC/MS
