Veeda Clinical Research Interview Questions and Answers

The ionisation mode is selected based on the type of sample and the information required from the analysis.

• Consider the polarity of the sample and the analyte of interest

• Determine the type of information required from the analysis

• Evaluate the sensitivity and selectivity of different ionisation modes

• Examples: ESI for polar compounds, APCI for non-polar compounds, MALDI for large biomolecules

ESI and APCI are ionization techniques used in mass spectrometry.

• ESI stands for Electrospray Ionization and is used for analyzing polar and charged molecules.

• APCI stands for Atmospheric Pressure Chemical Ionization and is used for analyzing non-polar and neutral molecules.

• Both techniques involve ionizing the sample molecules to create ions that can be analyzed by mass spectrometry.

• ESI is commonly used in proteomics and metabolomics research, while APCI is used in pharmaceutic...read more

Turnover for internal audit refers to the rate at which employees leave the internal audit department and are replaced.

• Turnover for internal audit can be calculated by dividing the number of employees who left the internal audit department by the average number of employees in the department during a specific period.

• High turnover in internal audit can indicate potential issues such as lack of career growth opportunities, poor management, or work-life balance.

• Low turnover in i...read more
