Industry:Chemistry
An analytical device that converts the concentration of an analyte in an appropriate sample into an electrical signal by means of a biologically derived sensing element intimately connected to, or integrated into, a transducer.
Industry:Chemistry
Quantitative chemical analysis that is based on measurement of the absolute disintegration rate of a radioactive component having a known specific activity.
Industry:Chemistry
Evidence for the presence or the identity of a substance that is obtained by techniques such as spectroscopy, chromatography, or electrophoresis.
Industry:Chemistry
In a chemical analysis, the measured value that is obtained in the absence of a specified component of a sample and that reflects contamination from sources external to the component; it is deducted from the value obtained when the test is performed with the specified component present. Also known as analytical blank.
Industry:Chemistry
Use of radioactive indicator to track the transfer of material between two liquid phases in equilibrium, such as titration of <sub>110</sub>AgNO<sub>3</sub> (silver nitrate, with the silver atom having mass number 110) against potassium chloride.
Industry:Chemistry
In chemical analysis, a selected sample whose composition is unknown except to the person submitting it; used to test the validity of the measurement process.
Industry:Chemistry
A substance, chemical, or solution used in the laboratory to detect, measure, or otherwise examine other substances, chemicals, or solutions; grades include ACS (American Chemical Society standards), reagent (for analytical reagents), CP (chemically pure), USP (U.S. Pharmacopeia standards), NF (National Formulary standards), and purified, technical (for industrial use).
