Beschreibung
Zusammenfassung:	A method of detecting an amine-based additive in wellbore servicing fluid (WSF) comprising contacting an aliquot of WSF with an amine detector reagent and aqueous medium to form a detection solution; wherein the amine detector reagent comprises an amine detector compound, and a polar organic solvent (POS) with flash point >105° C.; wherein the WSF comprises the amine-based additive; and wherein the detection solution is characterized by at least one absorption peak wavelength in 380-760 nm; detecting an absorption intensity for detection solution at a wavelength within ±20% of the at least one absorption peak wavelength; comparing the absorption intensity of detection solution at the wavelength within ±20% of the at least one absorption peak wavelength with a target absorption intensity of amine-based additive to determine the amount of amine-based additive in WSF; and comparing the amount of amine-based additive in WSF with a target amount of amine-based additive.
