Sun Pharmaceutical Industries Quality Analyst Interview Questions, Process, and Tips

Chromatography is a technique used to separate and analyze mixtures of chemicals based on their properties.

• Types of chromatography include gas chromatography, liquid chromatography, ion exchange chromatography, and affinity chromatography.

• Gas chromatography separates compounds based on their volatility and interactions with a stationary phase.

• Liquid chromatography separates compounds based on their affinity for the mob...read more

Troubleshooting of HPLC and GC involves identifying and resolving issues with the equipment to ensure accurate results.

• Perform regular maintenance checks on the equipment to prevent issues

• Calibrate the instruments regularly to maintain accuracy

• Check for leaks, blockages, or contamination in the system

• Verify the integrity of columns and detectors

• Review method parameters and conditions for any errors or inconsistencies

Types of titration include acid-base titration, redox titration, complexometric titration, and precipitation titration.

• Acid-base titration involves the neutralization of an acid with a base or vice versa.

• Redox titration involves a redox reaction between the analyte and titrant.

• Complexometric titration involves the formation of a complex between the analyte and titrant.

• Precipitation titration involves the formation of a

Types of HPLC columns include reverse phase, normal phase, ion exchange, size exclusion, and affinity. Types of GC columns include packed, capillary, and micro-packed columns.

• HPLC columns: reverse phase, normal phase, ion exchange, size exclusion, affinity

• GC columns: packed, capillary, micro-packed
