摘要： A method for monitoring the microbiological contamination of opaque media is described and claimed. In this method, a Fluorogenic Dye is added to an Aliquot of opaque medium. After a certain time period, a fluorometer capable of measuring fluorescent signals in an opaque medium is used to measure the fluorogenic signals of the Fluorogenic Dye and the Reacted Fluorogenic Dye. A Useful RATIO of the fluorescent signal of the Reacted Fluorogenic Dye to the fluorescent signal of the Fluorogenic Dye is calculated and the information gleaned from the RATIO is used to ascertain the state of microbiological contamination in the opaque medium.

摘要： A method for determining the presence of ferrous ion in boiler waters is described. The method can be used to directly measure the rate of corrosion occurring in boiler waters, and can measure the corrosion rates in the presence of boiler water treatment chemicals. The method uses a complex formed between only ferrous ion and a chemical 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-p,p'-disulfonic acid monohydrate reagent.

摘要： The invention provides a method and apparatus for determining the amount of various materials in a liquid sample. Because the apparatus is particularly resilient it can be used repeatedly with very harsh liquid samples such as boot water from an oil refinery. The apparatus uses at least one volume and/or concentration independent optical analysis method to determine at least one of: the pH, amount of chloride, and/or amount of iron in the sample. The optical property can be colorimetric, fluorescent or both and result from adding dyes, complexing agents, turbidity inducing compounds, and other optically effecting reagents to the sample. Because the measurements are concentration and volume independent they can be done continuously, quickly, and avoid the inconvenient start and stop procedures in prior art measurement regimens. The method further includes using a BDD cell to oxidize materials (such as sulfoxy compounds) that would otherwise interfere with the optical analysis and/or to sparge the sample with gas.
