if the sample is a drug
ASSAY
Involves the identification of the following:
• composition determination
• ascertainment of impurities present in a given sample
• Answers the question: WHAT IS PRESENT IN A GIVEN SAMPLE?
QUALITATIVE
determination of the proportion of components in a given sample
Answers: HOW MUCH IS
PRESENT IN THE SAMPLE?
QUANTITATIVE
Totality of characteristics or features of a product that bears on its capacity to satisfy stated or implied needs
QUALITY
• sum total of the organized arrangements made with the object of ensuring that products will be consistently of the quality required by their intended use
• based on process approach
• done before starting a project
• proactive or preventive process to avoid defects
QUALITY ASSURANCE
part of GMP concerned with sampling, specifications, testina organization • product based approach
• checks deliverables if it satisfy the quality requirements and specifications of customers
• begins once the product is manufactured
QUALITY CONTROL
statement of ingredients (% age, wt)
FORMULA
purity of ingredient
RAW MATERIAL SPECIFICATION
step by step method; covers instructions in the production

PROXIMATE
involves crude drugs and natural products derived from them
eg. Water content determination,
Ash content, Acid
MISCELLANEOUS/SPECIFIC METHOD
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
based on some specific physical or chemical property/ properties of the substance being analyzed
• involve instrumental techniques such as chromatography,
spectrophotometry, refractometry, polarimetry
PHYSICOCHEMICAL METHOD
the separation by extraction, precipitation, or other means of the constituent to be determined either in the natural state or in the form of a definite compound the composition of which is known to the analyst, and the weighing of the resulting product
GRAVIMETRIC ANALYSIS
those which require a distinct type of technique such as alkaloidal assaying
SPECIAL METHOD
