Diagram used in fuel Orsat analyses by plotting percent by volume CO<sub>2</sub> (carbon dioxide) maximum in the fuel (ordinate) versus percent by volume O<sub>2</sub> (oxygen) in air (abscissa); O<sub>2</sub> and CO<sub>2</sub> Orsat readings should fall on a line connecting these maximum values if the analysis is proceeding properly.
Industry:Chemistry
A visual-extinction device for measurement of solution turbidity; the length of the column of liquid suspension is adjusted until the light filament can no longer be seen.
Industry:Chemistry
Laboratory reagent consisting of potassium phosphate and calcium phosphate, magnesium sulfate, and ammonium tartrate in distilled water.
Industry:Chemistry

Industry:Chemistry
A bioassay that uses a set of histidine auxotrophic mutants of Salmonella typhimurium for detecting mutagenic and possibly carcinogenic compounds.
Industry:Chemistry
A test for monosaccharides conducted in an acid solution; cupric acetate is reduced to cuprous oxide, a red precipitate.
Industry:Chemistry
A solution of potassium and sodium tartrates, copper sulfate, and sodium carbonate; used to detect reducing sugars.
Industry:Chemistry
Laboratory reagent used to determine the concentration of sugars in solution by color titration; contains copper sulfate, sodium potassium tartrate, sodium hydroxide, and ammonia in water solution.
Industry:Chemistry
