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
Type of reagent water used in most lab/reagent/QC/Standard prep
Type 2
Type of reagent water used for most qualitative tests. Also used in histology, UA, FA, Washing, Autoclaved washed water.
Type 3
Water used for internal instrument rinsing, making dilutions, etc.
Instrument feed water
Water purification used in distillation, evaporation then the vapor will be condensed and harvested
Distilled water
Water purification that uses resin to selectively remove ion. For electrolyte analysis/assay
Deionized water
It pumps water across a semi permeable membrane
Reverse osmosis water
It denatures protein or decontaminate microbio room.
Ultraviolet
Total killing of microbes.
Sterilization
Most effective sterilization
Moist heat/autoclave
Most safest sterilization
Incineration
Unstable gas compromising 3 oxygen
Ozone treatment
It removes organic matter and chlorine
Activated carbon
It is expressed as percent solution
Concentration
Extent of dilute. Relatively little solute.
Saturation
Large quantity of solute
Concentrated
Excess undissolved solute
Saturated
Has an even greater concentration that is saturated.
Supersaturated
