Aashirvad Analytical Services Interview Questions, Process, and Tips

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

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
