Zydus Lifesciences Senior Executive Interview Questions, Process, and Tips

UV spectroscopy is a technique that uses ultraviolet light to measure the absorption or transmission of light by a sample.

• UV spectroscopy is commonly used in chemistry and biochemistry to analyze the structure and purity of molecules.

• It can be used to determine the concentration of a substance in a sample.

• UV spectroscopy can also be used to study the kinetics of chemical reactions.

• The working theory behind UV spectrosc...read more

Distillation is a process of separating components of a liquid mixture based on differences in boiling points.

• Distillation involves heating the liquid mixture to create vapor, then cooling the vapor to collect the separated components.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used for separating components with significantly different boili...read more

Heat transfer can occur through conduction, convection, or radiation.

• Conduction is the transfer of heat through direct contact between materials, such as a metal spoon heating up in a hot drink.

• Convection is the transfer of heat through the movement of fluids, such as boiling water in a pot.

• Radiation is the transfer of heat through electromagnetic waves, such as the heat from the sun reaching the Earth.

Different types of agitators in reactors include paddle, anchor, turbine, and propeller. Each agitator provides a different type of flow such as axial, radial, or tangential flow.

• Types of agitators include paddle, anchor, turbine, and propeller

• Paddle agitators provide axial flow

• Anchor agitators provide radial flow

• Turbine agitators provide both axial and radial flow

• Propeller agitators provide tangential flow
