摘要： Analyzing the level of a treating agent and/or stress metals in a body of water containing an inert transition metal tracer added to the water proportionally with the treating agent by determining the absorbance (first absorbance value) of a reagent dye added to water, said dye producing a second absorbance value when reacted at the same concentration with the tracer and stress metals in a measure of said body of water, and said dye producing a third absorbance value when reacted at the same concentration with only the transition metal contained in a measure of said body of water; determining the second and third absorbance values and resolving their differences to determine the concentration of the tracer and, separately, the concentration of said stress metals.

摘要： The performance of a treating agent added to a body of water employed in a cooling tower is continuously monitored by real-time analysis of a spectral or chemical characteristic of an inert tracer proportioned to the treating agent, said characteristic being indicative of tracer concentration, and converted to a voltage analog. The voltage analog is compared to a monitor value representing par performance and if performance is nonstandard (nonpar) a signal is generated which alters the output of a pump which feeds the dosage of treating agent containing proportioned tracer.

摘要： A method to determine performance of a treating agent (CA) added to a system body of liquid to enhance performance of the liquid body is determined by employing an inert fluorescent tracer (T) in a known T:CA dosage proportion, prepared on the basis of a concentration of CA (e.g. ppm) proposed for optimum performance in the liquid body. The system liquid is sampled and, on the basis of fluorescent emission, the sampled indicator is compared to a standard ppm concentration of T to determine the concentration and efficacy of CA and the physical characteristics and operating parameters of the liquid body.

摘要： Disclosed is a method of monitoring and optimizing the concentration of a denaturant composition in a fuel ethanol. The method includes adding a known amount of the denaturant composition to the fuel ethanol to create a treated fuel ethanol. A measured spectroscopic absorbance or transmittance signal provides information for determining the concentration of the denaturant composition in the fuel ethanol. A component in the denaturant composition is capable of providing the spectroscopic absorbance or transmittance signal or capable of being chemically derivatized to provide a spectroscopic absorbance or transmittance signal. Based upon the measured spectroscopic absorbance or transmittance signal, the concentration of the additive composition in the fuel ethanol may be adjusted.
