| Question | Answer |
|---|---|
| Analytic chemicals that exist in varying grade of purity | CHEMICAL REAGENT |
| CHEMICAL REAGENT ex (CANUT) | Analytic Reagent, Chemically Pure, US Pharmacopeia, National Formulary, Technical/Commercial Grade |
| High degree of purity of CHEMICAL REAGENT; Suitable for use in most analytic laboratory procedures | Analytic Reagent (AR |
| Sufficiently pure of CHEMICAL REAGENT; Not recommended for clinical laboratory reagent preparation unless it undergoes further purification or a reagent blank is included | Chemically Pure (CP) |
| Less pure than CP grade chemicals Used to manufacture drugs; WHAT CHEM REAGENT? | United States Pharmacopeia (USP), National Formulary (NF) |
| Should not be used in clinical chemical analysis without previous purification; what CHEM REAGENT | Technical/Commercial Grade |
| Material or substance with one or more physical or chemical properties that is sufficiently we l-established to be used for: a) Calibrating instruments b) Validating methods c) Assigning values to materials d) Evaluating the compatibility of results | Reference Materials |
| Reference Materials ex (CAVE) | Calibrating instruments, Validating methods, Assigning values to materials, Evaluating the compatibility of results |
| Classification of REFERENCE MATERIALS | Primary & Secondary RM |
| Highly purified chemicals that are directly weighed or measured to produce a solution whose concentration is exactly known; what RM? | Primary Reference Material |
| Solutions whose concentrations cannot be prepared by weighing the solute and dissolving a known amount into a volume of solution; what RM? | Secondary Reference Material |
| A process in which centrifugal force is used to separate solid matter from a liquid suspension | Centri |
| Centrifugation is used to? | Separate two immiscible liquids, Separate serum or plasma from the blood cells, Separate supernatant from a precipitate during analytic reaction |
| solid material or sediment packed at the bottom of the centrifuge tube | Precipitate |
| liquid or top portion | Supernatant |
| Principle of CENTRI | Centrifugal Force, Relative Centrifugal Force (RCF), Revolution per Minute (RPM) |
| Depends on mass, speed, and radius | Centrifugal Force |
| Force required to separate two phases in a centrifuge | Relative Centrifugal Force (RCF) |
| Expression of speed | Revolution per Minute (RPM) |
| Any meaningful quantitative laboratory result consists of two components: a) Numeric value, b)Label identifying the units of expression | UNITS OF MEASUREMENT |
