Alembic Pharmaceuticals Research Associate Interview Questions and Answers

HPLC stands for High Performance Liquid Chromatography. It is a technique used to separate, identify, and quantify components in a mixture.

• HPLC is a widely used analytical technique in chemistry and biochemistry.

• It involves the use of a liquid mobile phase and a solid stationary phase to separate the components of a mixture based on their interactions with the stationary phase.

• The components are separated based on thei...read more

Zetasizer measures particle size and zeta potential while Mastersizer measures particle size distribution.

• Zetasizer uses dynamic light scattering to measure particle size and zeta potential.

• Mastersizer uses laser diffraction to measure particle size distribution.

• Zetasizer is used for colloidal systems while Mastersizer is used for dry powders and granules.

• Zetasizer can measure particles in the range of 0.3 nm to 10 mic...read more

HPLC and UPLC are both chromatography techniques used for separation and analysis of compounds, but differ in their operating pressures and particle sizes.

• HPLC uses larger particle sizes and operates at lower pressures than UPLC.

• UPLC uses smaller particle sizes and operates at higher pressures than HPLC.

• UPLC provides higher resolution and faster separations than HPLC.

• HPLC is more commonly used for routine analysis, whi...read more
