QUANTI (ANACHEM) Flashcards
May be defined as the application of the procedures of Quantitative Analytical Chemistry.
QUANTITATIVE PHARMACEUTICAL CHEMISTRY
To the analysis and determination of the PURITY AND QUALITY OF DRUGS AND CHEMICALS used in pharmacy, official in USP/NF.
QPC
To the ANALYSIS OF MEDICINAL AGENTS AND THEIR METABOLITES found in biological system.
QPC
the DETERMINATION OF THE VOLUME of a solution of known concentration required to react with a given amount of the substance to be analyzed.
VOLUMETRIC ANALYSIS
chromatographic, spectrophotometric, electrometric, thermal conductrimetric, refractrometric, polarimetric, etc.
INSTRUMENTAL TECHNIQUES APPLIED IN QPC
Is achieved NOT BY HASTE, BUT BY PLANNING THE WORK so that two or more operations
may be carried out at one time.
ECONOMY OF TIME
The reagents used in quantitative analysis must be
PURE
Refers to the NUMERICAL DIFFERENCE between a MEASURED value and the TRUE value.
ERRORS
Of any quantity is really something never know.
TRUE VALUE
Also known as RANDOM ERROR
INDETERMINATE ERRORS
Cause: Inability of the eye to detect slight changes in a readout device.
INDETERMINATE ERRORS
Also known as SYSTEMATIC ERROR.
DETERMINATE ERRORS
Caused by faulty procedure
ERROR OF METHOD
Due to poor construction or calibration
APPARATUS ERROR
Are made of high-grade porcelain
CAN WITHSTAND HIGH TEMPERATURES
Use in the ignition of most drugs and precipitates
CRUCIBLE
