Difference among Calibration, Validation & Qualification
A lot of pharmaceutical professionals are having a big confusion among calibration, validation and qualification, hence I am trying to wash out the confusion. I think it will make a clear image of these three concepts and their definitions.
Handling of Out of Calibration Instruments and Equipment
Procedure for Instruments / Equipment other than Quality Control Laboratory
1. Stop usage of instrument/ equipment if it fails in calibration test or if there is a sudden malfunction in the instrument.
2. Affix “UNDER MAINTENANCE” label to the instrument/ equipment.
3. Fill an “Incident Report” and inform engineering department.
4. Engineering department shall carry out the investigation to find th…

Principle and Calibration of TOC (Total Organic Carbon) Analyzer
Introduction of organic matter into water systems occurs not only from living organisms and from decaying matter in source water but also from purification and distribution system materials. A relationship may exist between endotoxins, microbial growth, and the development of biofilms on pipeline walls and biofilm growth within pharmaceutical distribution systems. A correlation is believed to exi…
Principle and Calibration of Ultraviolet and Visible Absorption Spectrophotometry
Ultraviolet and visible absorption spectrophotometry is the measurement of the absorption of monochromatic radiation by solutions of chemical substances, in the range of 185 nm to 380 nm, and 380 nm to 780 nm of the spectrum, respectively. The magnitude of the absorption of a solution is expressed in terms of the absorbance, A, defined as the logarithm to base 10 of the reciprocal of transmittance…

Calibration of volumetric flasks
Weigh a clean & dry volumetric flask. Calibrate the flask by filling it with recently boiled and cooled distilled water at room temperature up to the mark and weigh the flask. Determine the volume in ml by the formula;
Volume (in ml) = (Weight in g / 0.99602) Where 0.99602 g is the weight of 1 ml water determined at temperature 25°C.
For the volumetric flask…
