Although relatively unknown, the instrumentation for 2DLC was conceived and implemented by Emi and Frei (1978). They reported the valve configuration presently used in most comprehensive 2DLC systems. However, they automated neither the valve nor the data conversion process to obtain a contour map or 2D peak display. They used a gel permeation chromatography (GPC) column in the first dimension and a reversed-phase liquid chromatography (RPLC) column in the second dimension and studied complex plant extracts. [Pg.13]

Reversed phase liquid chromatography-mass spectrometry was applied to extracts of Jamaica Bay (New York) water to determine 1-300 xg/l amounts of nonyl phenol ethoxylates and their metabolites [213]. [Pg.403]

The UV/VIS LC/MS analysis of an acetone extract of spinach leaves is shown in Figure F4.5.3 and Figure F4.5.4. Reversed-phase C18 chromatography was used with UV/VIS photodiode array absorbance detection followed on-line by positive ion APCI mass spectrometry. The mobile phase consisted of a 20-min linear gradient from methanol to metha-nol/methyl tert-butyl ether (91 9 v/v). The visible absorbance chromatogram at 613 nm for... [Pg.965]
