Abstract: Stabilized indicator compositions, and systems and methods using the same are described. In embodiments the stabilized indicator compositions include a solvent, an indicator, a stabilizer for the indicator, and optionally a buffer. In embodiments the indicator is or includes N, N-diethyl-p-phenylene diamine (DPD). Systems and methods utilizing the stabilized indicator composition to determine an amount of at least one constituent in a test sample (e.g., water) are also described. In embodiments, the systems and methods remove the stabilizer from the stabilized indicator composition to produce a fluid flow containing un stabilized indicator, which is then combined with a fluid from a sample source to form a test sample for analysis.
