Ans Qualitative analysis involves identification of the compound or chemical based on their chemical absorption, emission or physical properties e. Quantitative analysis involves estimation or determination of concentration or amount of the chemical compounds or components.
Ans UV spectroscopy uses light in the UV part of electromagnetic spectrum. UV absorption spectra arises in which molecule or atoms outer electrons absorb energy, undergoes transition from lower energy level to higher energy level. For each molecule, absorbance at wavelength is specific. Ans It states that the intensity of monochromatic light absorbed by a substance dissolved in a fully transmitting solvent is directly proportional to the substance concentration and the path length of the light through the solution.
Ans When a molecule absorbs the Infrared radiation, it vibrates and gives rise to packed Infrared IR absorption spectrum. This IR spectrum is specific for every different molecule absorbing the IR radiation, useful for its identification. Ans It is a technique used for separating the mixture of components into individual components based on adsorption, partition, ion exchange and size exclusion principles.
Stationary phase and mobile phase used in it. HPLC used for identification, quantification and purification of components form a mixture. Firstly, solvent mobile phase is degassed for eliminating the bubbles.
It is passed through the pump with a uniform pressure. The liquid sample is injected into the mobile phase flow stream. It passes through the stationary phase identified by the detectors and recorded.
Relative humidity- Water vapour amount exists in air expressed as a percentage of the amount needed for saturation at the same temperature. I have prepared a few more important questions and answers for you. You can also visit additional qc interview questions here. Follow this website for more qc pharma interview questions. If you have any queries comment below. We have provided interview questions for quality assurance in pharmaceutical industry here.
There is no specified differences between quality control and quality assurance from interview point of view. They are all interlinked. But we tried to prepare in separate posts and produced. This post is an extension to our previous interview questions for quality assurance in pharmaceutical industry.
If you attending an interview, you have to all these questions and answers in these 4 posts. It helps you a lot to face interview well.
Changes which were made to materials or procedures or methods or equipment or software should be documented properly. These changes should approved, validated and able to traceable.
Change control deals and makes sure all these changes. Ans These are the study designs for stability testing. In a full study design, you have to test the samples of all the design factors at all time points. Bracketing and Matrixing are reduced study designs. When multiple design factors involved in a study, these are the best alternatives to full study design.
If you use these designs, you need not to test all the samples at all time points. These study designs mostly used when multiple design factors involved. Bracketing supposes that tested extremes stability represents the intermediate levels stability of that study factor. Matrixing: In this schedule, at a specific time point a selected subset of the total number of possible samples for all factor combinations would be tested. At a next or subsequent time point, all the factor combinations for another subset would be tested.
While doing this sought help from your friends and seniors who are in similar position or industry. Pharmacy fresher, as well as experienced persons, are eligible to apply. In the pharmaceutical industry, usually, one should qualify the first round of exam for attending the face to face interview.
It also depends on which pharmaceutical company you are applying for. It is very important to understand the job profile and what kind of individual is needed for that position. For that clarity, you have to identify your strengths and weaknesses. It is advisable not to enter into any kind of argument with Interviewer. Accept that the interviewer s have more experience, listen carefully to them and never argue to justify your point during the interview. Besides knowledge, organizations prefer to choose people who are honest and also flexible in their approach.
Rigidity in approach may cost you your position as the business environment is changing very fast these days. Before the interview closes, it is better to ask for feedback from interviewer irrespective of how your interview went. With this, the impact becomes Organization members feel that candidate has a seeking attitude and is willing to accept feedback resulting in a favorable impression about the candidate. Below some are given to have an idea of what sort of questions one may prepare.
What is the difference between quality assurance and quality control? The liquid sample is injected into the mobile phase flow stream. It passes through the stationary phase identified by the detectors and recorded.
