    摘要: A titration method uses a tracer in the titrant or titrand to quantify the amount of titrant added. The method does not require quantitative addition of titrant or sample. The tracer can be inert or can participate as an indicator of the titrant-analyte reaction. If the tracer is inert, an alternative method for monitoring the progress of the titration is required. The tracer concentration is quantified by an appropriate method depending upon the type of tracer and analytical performance desired (e.g. precision, accuracy). The method simplifies titrations because it eliminates the need for a precision dispensing device and analytical balance.
