Chiral recognition of carboxylic acids has been achieved using a “host-metal-guest complexation system” by the ESIMS/EL-guest method. The system consists of a nitrogen-containing acyclic host, La(NO3)3, and carboxylic acids. Chiral recognition in the system is evaluated by the IRIS value, which is defined by the relative peak intensities of the corresponding host-metal-guest complex ions:IRIS = I [(H-La+3-GR-1(Gref-1))+1] / I [(H-La+3-GS-dn-1(Gref-1))+1]The IRIS values vary from 0.62 to 1.61 and a quantitative cross chiral relationship satisfactorily holds.
