Escientia Advanced Sciences Executive Interview Questions, Process, and Tips

System suitability parameters are criteria used to ensure that an analytical method is suitable for its intended purpose.

• System suitability parameters include resolution, peak symmetry, retention time, and tailing factor.

• These parameters are used to assess the performance of an analytical method and ensure reliable and accurate results.

• For example, in chromatography, system suitability parameters are used to evaluate t...read more

There are two main types of columns used in chromatography: packed columns and capillary columns.

• Packed columns are filled with a stationary phase material, such as silica or polymer beads.

• Capillary columns have a thin film coating on the inner surface, which serves as the stationary phase.

• Examples include gas chromatography columns, liquid chromatography columns, and ion exchange columns.

The range of pH values is from 0 to 14, with 7 being neutral.

• pH values below 7 are acidic, with 0 being the most acidic

• pH values above 7 are alkaline or basic, with 14 being the most basic

• A pH of 7 is considered neutral, neither acidic nor basic

Calibration procedure involves setting up and adjusting equipment to ensure accurate measurements.

• Calibration involves comparing measurements of two instruments, one with a known magnitude and the other with unknown magnitude.

• Parameters for calibration include temperature, pressure, voltage, etc.

• Calibration procedures should be documented and followed regularly to maintain accuracy.

• Examples of calibration parameters: z...read more
