Sai Parenterals QC Executive Interview Questions, Process, and Tips for Experienced

HPLC is a technique used to separate, identify, and quantify components in a mixture.

• Sample preparation

• Injection of sample into the column

• Separation of components based on their interaction with the stationary phase

• Detection and quantification of separated components

• Data analysis and interpretation

Various instruments are used in QC such as spectrophotometers, chromatographs, pH meters, balances, and microscopes.

• Spectrophotometers are used to measure the amount of light absorbed by a sample.

• Chromatographs are used to separate and analyze components in a mixture.

• pH meters are used to measure the acidity or alkalinity of a solution.

• Balances are used to measure the mass of a sample.

• Microscopes are used to observe an

KF is used to measure water content in a sample while LOD is used to measure the amount of volatile matter in a sample.

• KF stands for Karl Fischer titration and is used to measure the water content in a sample.

• LOD stands for Loss on Drying and is used to measure the amount of volatile matter in a sample.

• KF is more accurate than LOD for measuring water content.

• LOD is more commonly used in the pharmaceutical industry to d...read more
