Optimus Pharma Executive Interview Questions and Answers

A pH meter is a scientific instrument used to measure the acidity or alkalinity of a substance. Calibration ensures accurate readings.

• pH meter measures the concentration of hydrogen ions in a solution

• Calibration involves adjusting the pH meter to known standard solutions

• Regular calibration ensures accurate readings over time

HPLC stands for High Performance Liquid Chromatography, which consists of a pump, injector, column, detector, and integrator.

• HPLC involves a pump to push the liquid solvent through the system.

• It includes an injector to introduce the sample into the mobile phase.

• The column separates the components of the sample based on their interactions with the stationary phase.

• A detector measures the amount of analyte in the eluent.

Buffers commonly used in HPLC include phosphate buffers, acetate buffers, and citrate buffers.

• Phosphate buffers are commonly used in HPLC for separating acidic compounds.

• Acetate buffers are used for separating basic compounds.

• Citrate buffers are used for separating metal ions.

• Other common buffers used in HPLC include ammonium acetate and ammonium formate.

HPLC calibration involves adjusting parameters to ensure accurate and reliable results.

• Prepare standard solutions of known concentrations

• Run the standard solutions through the HPLC system

• Compare the results to expected values and adjust parameters as needed

• Repeat the process until accurate and consistent results are obtained

Recall process is a procedure used to remove or correct products that have been found to be unsafe or defective.

• Identify the issue or defect in the product

• Notify relevant stakeholders including customers, suppliers, and regulatory agencies

• Determine the scope of the recall (e.g. specific batch, entire product line)

• Develop a communication plan for informing the public

• Implement the recall by removing the product from shel...read more

Calibration of HPLC is a process to ensure accuracy and reliability of the instrument for accurate analysis.

• Calibration involves checking the accuracy of the HPLC system by comparing the results with known standards.

• Calibration should be performed regularly to ensure consistent and reliable results.

• Parameters such as flow rate, detector sensitivity, and retention time should be calibrated.

• Calibration curves are used to...read more

HEPA filters are highly efficient filters that can capture 99.97% of particles as small as 0.3 microns.

• HEPA filters are designed to capture particles such as dust, pollen, mold, bacteria, and viruses.

• They are commonly used in air purifiers, vacuum cleaners, and HVAC systems.

• HEPA filters are essential in environments where clean air is crucial, such as hospitals, laboratories, and clean rooms.

The formula of sulphuric acid is H2SO4.

• The formula of sulphuric acid consists of hydrogen (H), sulfur (S), and oxygen (O) atoms.

• It is a strong mineral acid with the chemical formula H2SO4.

• Sulphuric acid is commonly used in various industrial processes such as in batteries, fertilizers, and chemical synthesis.

Toluene is a colorless liquid with a benzene ring and a methyl group attached.

• Toluene has a chemical formula of C7H8

• It consists of a benzene ring with a methyl group attached

• The molecular structure of toluene is represented as C6H5CH3

The formula of Benzene is C6H6.

• Benzene is a cyclic hydrocarbon with a ring of six carbon atoms and six hydrogen atoms.

• The molecular formula of Benzene is C6H6.

• Benzene is represented as a hexagon with a circle inside to indicate delocalized electrons.

Chemical name and formula are identifiers for specific chemical compounds.

• Chemical name is the common name given to a chemical compound.

• Chemical formula represents the elements and their ratios in a compound.

• Example: Water - Chemical name, H2O - Chemical formula.

To make 0.1M HCL, dilute concentrated hydrochloric acid with water.

• Dilute 1 part of concentrated HCL with 9 parts of water to make 0.1M HCL solution.

• Always add acid to water slowly to prevent splashing and heat generation.

• Use proper protective equipment such as gloves and goggles when handling acids.
