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%.
在荧光法直接测定中，检测限受溶液中荧光增白剂（FWAs）有限的光稳定性限制。荧光读数的初始值可用快速记录仪记录，这样，低至十亿分之十的极微量FWAs都能被检测到，单次测量的统计标准偏差为±15%，在99%的统计置信度下，重现性为±50%。
