N-methyl carbamates in Black pepper
Posted: Tue Apr 03, 2007 9:51 am
Hi All,
Anyone tried analysing N-methyl carbamate (NMC) pesticide in Black pepper. This sample matrix is problematic as is has this oily substance that is co-extracted with Acetonitrile and C18 and aminopropyl SPE can't remove it. Tried GPC but it seems to elute together with my analytes. Help me please.
