MSN Laboratories Interview Questions, Process, and Tips

Resolution is the ability to distinguish between two closely spaced objects or the ability to distinguish between two closely spaced peaks in a chromatogram.

• Resolution is a measure of the clarity or sharpness of an image or signal.

• It is commonly used in microscopy, spectroscopy, and chromatography.

• Resolution is determined by factors such as the wavelength of light or radiation used, the numerical aperture of the lens, ...read more

Tailing factor is a measure of peak asymmetry in chromatography, indicating the presence of tailing or fronting.

• Tailing factor is calculated by dividing the distance from the peak apex to the leading edge of the peak by the distance from the peak apex to the trailing edge of the peak.

• A tailing factor of 1 indicates a symmetrical peak, while values greater than 1 indicate tailing and values less than 1 indicate fronting...read more

Theoretical plate is a hypothetical zone in a chromatographic column where separation of components occurs.

• Theoretical plate is a concept used in chromatography to describe the efficiency of a column.

• It is a hypothetical zone in the column where separation of components occurs.

• It is used to calculate the number of plates in a column.

• The more theoretical plates a column has, the better the separation of components.

• Theor...read more

Polar and nonpolar are terms used to describe the distribution of electrons in a molecule.

• Polar molecules have an uneven distribution of electrons, resulting in a partial positive and partial negative charge.

• Nonpolar molecules have an even distribution of electrons, resulting in no partial charges.

• Examples of polar molecules include water and ammonia, while examples of nonpolar molecules include oil and methane.

Handling SAR for reactors involves proper monitoring, documentation, and communication.

• Regular monitoring of SAR levels in reactors

• Documenting SAR data accurately for future reference

• Communicating any SAR-related issues or changes to relevant stakeholders

• Implementing safety measures to prevent SAR exceedance

• Training staff on SAR monitoring and handling procedures
