Tea protection racket: Protectants compensate for matrix effects in pesticides analysis of tea

Date: Nov 1, 2012

Author: Steve Down

A set of protectants has been evaluated for the GC/MS analysis of pesticides in three different types of tea to compensate for the matrix effects that complicate the gas chromatographic behaviour.

Conserving plastic objects in museums: Emitted volatiles act as exhibit degradation markers

Date: Oct 15, 2012

Author: Steve Down

Specific volatiles emitted from plastic objects in museums have been identified by SPME-GC/MS, giving a series of degradation markers and that will help with the preservation of valuable exhibits.
