Strides Pharma Research and Development Interview Questions and Answers

Distillation is a process of separating components of a liquid mixture based on their different boiling points.

• Distillation involves heating a liquid mixture to vaporize the more volatile components.

• The vapor is then cooled and condensed back into a liquid, resulting in the separation of the components.

• The component with the lower boiling point will vaporize first and can be collected separately.

• Common examples of dist...read more

There are various types of distillation, such as fractional distillation, simple distillation, and vacuum distillation.

• Fractional distillation is used to separate mixtures with close boiling points, such as in the separation of different components of crude oil.

• Simple distillation is used to separate liquids with significantly different boiling points, such as in the purification of water.

• Vacuum distillation is used to...read more

The type of pump and valve depends on the specific production process and requirements.

• The selection of pump and valve depends on factors such as the fluid being handled, flow rate, pressure, temperature, and material compatibility.

• Common types of pumps include centrifugal pumps, positive displacement pumps, and diaphragm pumps.

• Common types of valves include ball valves, gate valves, globe valves, and butterfly valves.

Developing HPLC methods involves selecting appropriate columns and optimizing parameters.

• Choose a suitable column based on the analyte's properties and the separation goal.

• Optimize parameters such as mobile phase composition, flow rate, and temperature.

• Validate the method by assessing its selectivity, sensitivity, accuracy, and precision.

• Common column types include C18, C8, and phenyl.

• Other factors to consider include ...read more

Carbon loading in column refers to the amount of carbon used in the stationary phase of a chromatography column. Endcapping is a process to block the remaining silanol groups on the surface of the stationary phase.

• Carbon loading is typically expressed as a percentage of the total weight of the stationary phase.

• Higher carbon loading can improve the selectivity and retention of certain analytes.

• Endcapping is important to...read more
