Dr. Reddy's QC Interview Questions and Answers

HPLC and HPTLC are analytical techniques used to separate and identify components in a mixture.

• HPLC stands for High Performance Liquid Chromatography and uses a liquid mobile phase to separate components based on their interactions with a stationary phase.

• HPTLC stands for High Performance Thin Layer Chromatography and uses a thin layer of stationary phase on a plate to separate components based on their interactions wi...read more

Pneumatic systems use compressed air to transmit power, while hydraulic systems use fluid to transmit power.

• Pneumatic systems use air as the working fluid, while hydraulic systems use liquid.

• Pneumatic systems are typically used for lighter loads and faster movements, while hydraulic systems are used for heavier loads and slower movements.

• Pneumatic systems are generally less expensive and easier to maintain compared to ...read more

There are several types of welding techniques used in various industries.

• Arc welding: Uses an electric arc to create heat and join metals.

• MIG welding: Uses a consumable wire electrode and shielding gas to join metals.

• TIG welding: Uses a non-consumable tungsten electrode and inert gas to join metals.

• Spot welding: Joins metal sheets by applying pressure and heat at specific points.

• Flux-cored arc welding: Similar to MIG w...read more

CNC and lathe machines are used for precision cutting and shaping of materials.

• CNC machines use computer programming to control the cutting tools, allowing for highly precise and complex shapes to be created.

• Lathe machines are used for turning and shaping cylindrical objects, such as metal rods or wooden dowels.

• Both machines are commonly used in manufacturing and engineering industries.

• Examples of products made using C...read more
