In this article an overview of time-domain quantitation methods is given, A
dvantages of processing the data in the measurement domain are discussed. T
he basic underlying principles of the methods are outlined and from them th
e situations under which these algorithms perform well are derived. Also an
overview of methods to preprocess the data is given. In that respect, sign
al-to-noise and/or resolution enhancement, the removal of unwanted componen
ts and corrections for model imperfections are discussed, Copyright (C) 200
