Determination of pesticides and their degradation products in soil: critical review and comparison of methods
Coupled-column RPLC (LC–LC) employs one analytical
column packed with a restricted access material
(RAM) and combines reversed-phase separation of lowmolecular-
mass analytes and size exclusion of large
molecular compounds with ABZ+, including a polar
embedded functional group. It largely eliminates the bad
chromatographic effect of interferences, as shown in Fig.
4 [33,42].
