Introduction Flashcards
A chemical substance that is the subject of chemical analysis
Analyte
A compound or a mixture added to a system to cause a chemical reaction or test if a reaction occurs
Reagent
Reagent used in most analytical laboratory procedures
Analytical Reagent grade
Reagent used for special procedures such as AAS, chromatography, molecular diagnostics, etc.
Ultrapure reagents
Drying agents that absorb water
Dessicants
Examples of dessicant
Magnesium perchlorate & Silica gel
Anything that speeds up the rate of a chemical reaction but is not being produced or consumed in the reaction.
Catalyst
Process of testing and adjusting analyzers readout to establish correlation between measured and actual concentrations.
Calibration
A material of known concentration. For calibrating instrument.
Standard/calibrator
Testing materials of known concentrations (calibrators, controls, proficiency testing, samples, patient specimens with known values) to ensure accuracy of results throughout the reportable range.
Calibration verification
Sample that is chemically and physically similar to unknown specimens and is tested in exactly the same manner.
Control
Values are assigned by the manufacturer
Assayed control
Values are determined by each individual laboratory.
Unassisted control
Most common water
Reagent water
Type of reagent water for maximum water purity. Used in ultramicrochem and tissue culture
Type 1
