MDB Chemicals Interview Questions and Answers

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

• Gas chromatography involves a sample being vaporized and injected into a column with a stationary phase.

• Compounds in the sample interact differently with the stationary phase, causing them to separate based on their properties.

• The separated compounds are then detected and identified based on their retention times.

• Gas chromatograph...read more

Analytical chemistry is the branch of chemistry that deals with the analysis of substances to determine their composition and properties.

• Analytical chemistry involves techniques such as spectroscopy, chromatography, and mass spectrometry.

• It is used to identify and quantify the components of a sample, as well as to determine its purity.

• Examples include testing the concentration of pollutants in water, analyzing the comp...read more

Liquid chromatography is a technique used to separate and analyze mixtures of chemicals based on their interactions with a stationary phase and a mobile phase.

• Choose the appropriate type of liquid chromatography based on the sample being analyzed (e.g. HPLC, UPLC, ion-exchange chromatography).

• Prepare the sample by dissolving it in a suitable solvent and injecting it into the chromatography system.

• The sample interacts w...read more

Quality assurance is the process of ensuring that products or services meet specified requirements and standards.

• Quality assurance involves creating processes and procedures to prevent defects in products or services.

• It includes testing and inspecting products to ensure they meet quality standards.

• Quality assurance also involves continuous monitoring and improvement of processes to maintain quality.

• Examples of quality ...read more

Organic chemistry deals with compounds containing carbon, while inorganic chemistry deals with compounds without carbon.

• Organic chemistry focuses on carbon-based compounds, including hydrocarbons, carbohydrates, proteins, and nucleic acids.

• Inorganic chemistry deals with compounds that do not contain carbon, such as salts, metals, minerals, and gases.

• Organic chemistry is primarily concerned with the study of living orga...read more
