Ploarographic Determination of Mixed Pyrazines by Principal Component Regression

Ni Yongnian (Department of Chemistry, Jiangxi University, Nanchang 330047)Kokot S, Selby M, Hodgkinson M (Department of Chemistry, Queensland University of Technology, Australia)  
The polarographic waves of pyrazine and its methyl derivatives are seriously overlapping, so they can not be determined individually by polarographic method without prior separation. In this paper, the chemometric approach, principal component regression, was applied to the determination of mixtures of pyrazines at trace level(0. 15-1μg/ml) by using differential pulse polarography and a static mercury drop electrode. It produced acceptable results with the recoveries of 95%-105% and the relative standard deviation of 4%-10%.
