APCI fungicides

A method has been reported for the quantification of five fungicides (shown in Figure 5.39) used to control post-harvest decay in citrus fruits to ensure that unacceptable levels of these are not present in fruit entering the food chain [26], A survey of the literature showed that previously [27] APCI and electrospray ionization (ESI) had been compared for the analysis of ten pesticides, including two of the five of interest, i.e. carbendazim and thiabendazole, and since it was found that APCI was more sensitive for some of these and had direct flow rate compatibility with the HPLC system being used, APCI was chosen as the basis for method development.

ESI with simazine as an internal standard was applied. Metabolisation but no mineralization could be observed [389]. APCI and ESI-MS were applied to determine humic substances and dissolved organic matter (DOM) together with the fungicide anilazine (2,4-dichlor-6-(2-chloranilino)-l,3,5-triazine) which was... 

LC-MS tandem apparatus equipped with ESI and APCI in both PI and NI modes was evaluated [133]. This study investigated the effects of matrix interferences on the analytical performance of a triple-quadrupole detector coupled to various reversed-phase liquid chromatographic. In Table 19.8, selected LC and GC methods for assaying herbicides and fungicides in water are listed.
