QC Assistant Interview Questions and Answers

A UV/Visible spectrophotometer determines the absorption and transmission of light by a sample.

• UV/Visible spectrophotometer measures the amount of light absorbed or transmitted by a sample in the UV and visible regions of the electromagnetic spectrum.

• It helps in determining the concentration of a substance in a solution by measuring the absorbance of light at a specific wavelength.

• It can be used to analyze the purity of a compound by comparing its absorption spectrum with a k...read more

Mobile phase is used in HPLC to carry the sample through the stationary phase and separate its components based on their interactions.

• Mobile phase carries the sample through the stationary phase in HPLC.

• It helps in separating the components of the sample based on their interactions with the stationary phase.

• The choice of mobile phase depends on the nature of the sample and the desired separation.

• Common mobile phases include water, organic solvents, and mixtures of both.

• For ex...read more

Columns are used in HPLC to separate and analyze components of a sample.

• Columns in HPLC contain a stationary phase that interacts with the sample components

• The stationary phase can be packed with different materials such as silica or polymer

• The choice of column depends on the analytes being separated and the desired separation efficiency

• Columns can have different dimensions and particle sizes to optimize separation

• Examples of column types include C18, C8, and phenyl columns

Yes, I have knowledge of testing including test planning, execution, and documentation.

• Experience in creating test plans and test cases

• Familiarity with executing test cases and documenting results

• Knowledge of different types of testing such as functional, regression, and performance testing
