analysis of CQSF was performed using an Thermo Finnigan, LCQDeca XP MAX ion trap MS (Germany) equipped with an ESI interface.
Based on the ESI-MS
peak width, composition was concluded to be Au~500 [+ or -] 10(SCH2CH2Ph)~120 [+ or -] 3.

The value of ESI-MS
for analyzing plant fatty acids and animal fats has been recognized since at least 1994.
V] using a combination of retention-time matching and by fortifying the sample with the suspected standard using separation 1 with ICP-MS detection, but we used a second chromatography (separation 2) for ICP-MS and ESI-MS
This monograph provides an overview of the mechanisms involved in ESI-MS
, the historical perspectives before looking further in-depth at specific reactions and intermediates.
We have believed from the start that the use of microfluidic devices to couple ESI-MS
with a chip will significantly advance the application of mass spectrometry to bioanalysis.
