. 2007 Feb;
79(6):2491-8.
PMID: 17288463
In this work, we compared APPI and APCI for normal-phase LC/MS chiral analysis of five pharmaceuticals. Performance was compared both by FIA and by on-column analysis using a ChiralPak AD-H...

J Chromatogr A
. 2004 Oct;
1050(2):137-49.
PMID: 15508306
In this paper we describe results based on the combination of atmospheric pressure photoionization (APPI) with atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI). The main purpose of combining...
