Privi Speciality Chemicals QC Officer Interview Questions and Answers

Q1. What is meant by Gas chromatography
Ans. 
Gas chromatography is a technique used to separate and analyze volatile compounds in a mixture.
• Gas chromatography involves the use of a stationary phase and a mobile phase.

• The stationary phase is a solid or liquid coating inside a column, while the mobile phase is a gas.

• The mixture is injected into the column, and as the mobile phase flows through, different compounds interact with the stationary phase at different rat...read more

Q2. Which buffet solution is used for ph meter calibration
Ans. 
Buffer solutions with known pH values are used for pH meter calibration.
• Buffer solutions with pH values of 4.01, 7.00, and 10.01 are commonly used for pH meter calibration.

• The choice of buffer solution depends on the pH range of the sample being tested.

• The buffer solutions should be stored properly and replaced regularly to ensure accurate calibration.

• Calibration should be performed before each use of the pH meter.
