Aashirvad Analytical Services Interview Questions, Process, and Tips

UV, FTIR, and KF are analytical instruments used in quality control. Calibration is essential for accurate results.

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

• FTIR spectrophotometer measures the absorption or transmission of infrared radiation by a sample.

• KF titrator is used for the determination of water content in a sample.

• Calibration involves setting up the instrument to ensure ...read more

Sulphated Ash and Residue on Ignition are two different methods to determine the amount of inorganic material in a sample.

• Sulphated Ash involves heating the sample with sulphuric acid to remove organic material and then heating the remaining inorganic material to constant weight.

• Residue on Ignition involves heating the sample to high temperature to burn off organic material and then heating the remaining inorganic mate...read more

Normality refers to the state of being normal or typical within a certain context.

• Normality is a statistical concept used to determine if a data set is normally distributed.

• In chemistry, normality is a measure of concentration of a solution, expressed as the number of equivalents of a solute per liter of solution.

• Normality can also refer to conforming to societal norms or standards of behavior.

• In psychology, normality ...read more

Titration is a technique used to determine the concentration of a substance in a solution by reacting it with a known concentration of another substance.

• Titration involves slowly adding a solution of known concentration (titrant) to a solution of unknown concentration (analyte) until the reaction reaches its endpoint.

• Types of titration include acid-base titrations, redox titrations, complexometric titrations, and preci...read more
