The development of laser-based polarimetric detectors for high-performance liquid chromatography (HPLC) (Yeung et al . 1980; Bobbitt & Yeung 1986) with noise levels in the range of 0.1-10 p° has provided a significant advance in the quantitation of chiral molecules. We have designed an instrument based on an 820 nm diode laser which has the advantages of low source flicker noise and compact design (Lloyd et al . 1989). Detection limits were found to be in the range 0.1-2 pg, dependent on the specific rotation of the chiral molecule and the chromatographic peak width (Goodall et al. 1990).

The electrospray ionization (ESI) responses, defined as the area of chromatographic peak of ion [M+H]+ obtained upon HPLC/ESI-MS analysis, of three β-lactam antibiotics, namely penicillin G, ampicillin and carbenicillin have been compared with the ESI responses of their methanolysis products. It has been found that methanolyzed penicillin G has much higher ESI response than the penicillin G. Methanolyzed ampicillin also has higher ESI response than ampicillin; however, the effect is less pronounced than for penicillin. Methanolyzed carbenicillin does not have pronouncedly higher ESI response than carbenicillin.
