✦ Synopsis

We describe here a new approach for multilabel immunoassays. The starting point of this approach is a new nonradioisotopic immunoassay (carbonyl metallo immunoassay) based on the use of metal carbonyl complexes as tracers and Fourier transform infrared (FT-ir) spectroscopy as the detection method. We show here that the judicious choice of the organometallic tracers associated with multicomponent analysis of FT-ir spectroscopic data provides the simultaneous rapid and reliable quantitation of pmol of the organometallic tracers. The feasibility of this approach is demonstrated in the case of the two major antiepileptic drugs phenobarbital and carbamazepine.

Fourier transform infrared (FT-IR) spectroscopy and chemometrics have been combined to detect adulteration in strawberry pure es. The mid-IR spectra of 983 fruit pure es were used as the data for a partial least squares regression on to a binary dummy variable, that represents two sample types, stra
