Drift correction--a comparative evaluation of some alternatives.
Three drift correction methods are described. The results obtained from computer simulation of these methods and their application to raw data obtained from a survey of multichannel continuous-flow analysers are discussed, with particular reference to the effects of each method on analytical precision and accuracy, and on between-analyser variation. A geometrically derived method of drift correction was found to be the most satisfactory.
