Microdetermination of carbon and hydrogen in organic compounds; the sample is prepyrolyzed (cracked) in a shortage of oxygen, then oxidized in an excess of oxygen.
Industry:Chemistry
A device used for emission flame photometry in which a compressed air aspirator vaporizes the solution within a chamber; smaller droplets are carried into the fuel-gas stream and to the burner orifice where the solvent is evaporated, dissociated, and optically excited.
Industry:Chemistry
A test for the presence of arsenic in a compound; the substance to be tested is mixed with granular zinc, and dilute hydrochloric acid is added to the mixture; gaseous arsine forms, which decomposes to a black deposit of arsenic, when the gas is passed through a heated glass tube. Also known as Marsh-Berzelius test.
Industry:Chemistry
Titration with silver nitrate to determine the concentration of chlorides in a solution; silver chromate precipitation is the end-point indicator.
Industry:Chemistry
Mercuric iodide-potassium iodide solution, used to analyze for small amounts of ammonia.
Industry:Chemistry
Standardized glass tubes for filling with standard solution colors for visual color comparison with similar tubes filled with solution samples.
Industry:Chemistry
Gas analysis apparatus in which various gases are absorbed selectively (volumetric basis) by passing them through a series of preselected solvents.
Industry:Chemistry
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.
