Serum Institute of India R&D Chemist Interview Questions, Process, and Tips

Chemistry is the scientific study of matter and its properties, structure, composition, and behavior.

• Chemistry involves the study of atoms, molecules, and their interactions.

• It is used to understand the properties and behavior of substances, and to develop new materials and technologies.

• Examples of chemistry in everyday life include cooking, cleaning, and medicine.

• Spectroscopy is a technique used in chemistry to study ...read more

HPLC is a high-performance liquid chromatography technique used to separate, identify, and quantify components in a mixture.

• HPLC uses a liquid mobile phase and a stationary phase to separate components based on their chemical properties.

• It is commonly used in pharmaceuticals, food analysis, and environmental testing.

• HPLC can detect and quantify very small amounts of compounds, making it a highly sensitive technique.

• Sim...read more

Gas chromatography is a technique used to separate and analyze compounds in a mixture.

• A sample is vaporized and injected into a column filled with a stationary phase.

• The compounds in the sample interact differently with the stationary phase and are separated as they travel through the column.

• The separated compounds are detected and identified based on their retention time and other properties.

• Gas chromatography is comm...read more

Passaging cells involves detaching cells from a culture vessel, diluting them, and transferring them to a new vessel to allow for continued growth.

• Use a sterile technique to detach cells from the culture vessel

• Collect the cells in a centrifuge tube and centrifuge to pellet the cells

• Resuspend the cells in fresh media and calculate the appropriate dilution factor

• Transfer the diluted cells to a new culture vessel and incu
