Biocon Limited Senior Quality Assurance Officer Interview Questions and Answers for Experienced

Normality refers to the state of being normal or conforming to a standard or average.

• Normality is a concept used in various fields to define what is considered typical or expected.

• It is often used in statistics to describe the distribution of data points around a mean.

• In psychology, normality refers to behavior that is within the range of what is considered socially acceptable.

• Normality can also be subjective, varying ...read more

Molarity is a measure of the concentration of a solution expressed as the number of moles of solute per liter of solution.

• Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.

• It is denoted by the symbol 'M'.

• Molarity is commonly used in chemistry to express the concentration of a solution.

• For example, a 1 M solution of sodium chloride contains 1 mole of sodium chloride

Molarity is the concentration of a solution in terms of the number of moles of solute per liter of solution, while molality is the concentration of a solution in terms of the number of moles of solute per kilogram of solvent.

• Molarity is denoted by M, while molality is denoted by m.

• Molarity is affected by temperature changes, while molality is not.

• Molarity is used in chemical reactions, while molality is used in colliga...read more

HPLC stands for High Performance Liquid Chromatography. It is a principle used in analytical chemistry to separate, identify, and quantify components in a mixture.

• HPLC uses a liquid mobile phase and a solid stationary phase to separate components based on their interactions with the stationary phase.

• The principle is based on the differential partitioning of components between the mobile and stationary phases.

• Components...read more

The principle of UV-spectrophotometer is based on the absorption of ultraviolet (UV) light by molecules.

• UV-spectrophotometer measures the absorbance of UV light by a sample.

• The absorbance is directly proportional to the concentration of the absorbing species in the sample.

• The principle is used in various applications such as quantitative analysis, purity determination, and kinetics studies.

• UV-spectrophotometer operates...read more

Quality assurance focuses on preventing defects while quality control focuses on identifying and correcting defects.

• Quality assurance is a proactive process that involves planning, designing, and implementing processes to prevent defects from occurring.

• Quality control is a reactive process that involves identifying defects and taking corrective action to eliminate them.

• Quality assurance is focused on the entire process...read more

pH is a measure of acidity or alkalinity of a solution. It is measured on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• It is a measure of the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• pH can be measured using pH meters, pH paper/strips, or pH indicators

Calibration ensures accuracy of instruments by comparing measurements to a known standard.

• Calibration is the process of adjusting an instrument to ensure its measurements are accurate.

• Principles of instruments include accuracy, precision, repeatability, and reproducibility.

• Examples of calibrated instruments include thermometers, scales, and pressure gauges.

Investigation tools are used to analyze data and identify issues in software development.

• Common investigation tools include debuggers, profilers, and log analyzers.

• Debuggers help identify and fix coding errors by allowing developers to step through code and inspect variables.

• Profilers analyze the performance of code, identifying bottlenecks and areas for optimization.

• Log analyzers parse and analyze log files to identif...read more
