In direct determination by fluorimetry the limits of detection are governed by the restricted light stability of fluorescent whitening agents (FWAs) in solution. The initial value of a fluorimetric reading can be registered by a rapid recorder, and in this way very light sensitive traces of FWAs as low as 10 parts per thousand million can be measured be measured with a statistical standard deviation of +/-15% for a single measurement and a reproducibility of +/-50% with a statistical certainty of 99%.
