Promea Therapeutics Executive Research Development Interview Questions, Process, and Tips

Principal of HPLC is based on the separation of components in a mixture using a liquid mobile phase and a solid stationary phase.

• HPLC stands for High Performance Liquid Chromatography.

• It involves the use of a liquid mobile phase to carry the sample through a column packed with a solid stationary phase.

• The components in the sample interact differently with the stationary phase, leading to separation based on their prope...read more

Formulation is the process of creating a specific mixture or combination of ingredients to achieve a desired outcome.

• Formulation involves selecting and combining ingredients in specific quantities.

• It is commonly used in industries such as pharmaceuticals, cosmetics, and food production.

• Examples include formulating a new medication, creating a skincare product, or developing a new recipe for a food product.

HPLC is a type of chromatography used for separating compounds in a mixture based on their interactions with a stationary phase and mobile phase.

• HPLC stands for High Performance Liquid Chromatography, while chromatography is a broader term encompassing various techniques for separating mixtures.

• HPLC typically uses a liquid mobile phase, while chromatography can use liquid, gas, or solid phases.

• HPLC is more precise and ...read more

The column used in HPLC is typically a stainless steel tube filled with a stationary phase.

• The column is a crucial component of the HPLC system, where the separation of compounds occurs.

• The stationary phase inside the column interacts with the mobile phase to separate the analytes based on their properties.

• Columns can vary in length, diameter, and particle size depending on the specific application.

• Common types of colu...read more

The column in HPLC is where the separation of compounds occurs based on their interactions with the stationary phase.

• The column is packed with a stationary phase material, such as silica or polymer beads

• Compounds in the sample mixture interact differently with the stationary phase, leading to separation

• The mobile phase carries the sample through the column, with compounds eluting at different times based on their inter...read more
