Eli Lilly and Company Quality Specialist Interview Questions and Answers

Acids and bases are substances that can donate or accept protons, respectively.

• Acids are substances that release hydrogen ions (H+) in water.

• Bases are substances that release hydroxide ions (OH-) in water.

• Acids and bases can also be defined based on their chemical properties, such as their ability to neutralize each other.

• Examples of acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4).

• Examples of bases incl

The season highly possible to produce static electricity is winter.

• Winter is a season with low humidity, which allows for the buildup of static electricity.

• Cold temperatures in winter can cause materials to become more electrically charged.

• Examples of static electricity in winter include getting shocked when touching a doorknob or seeing sparks when removing a sweater.

Distillation is a process used to separate mixtures based on differences in boiling points.

• Simple distillation: used to separate liquids with different boiling points

• Fractional distillation: used to separate liquids with similar boiling points

• Steam distillation: used to extract volatile compounds from plants

• Vacuum distillation: used to lower boiling points of high-boiling compounds

• Azeotropic distillation: used to separ...read more

PDA and UV detector are both used in HPLC analysis but differ in their detection mechanism.

• PDA detector measures the entire UV-Vis spectrum of the eluent while UV detector measures at a specific wavelength.

• PDA detector can provide more information about the sample while UV detector is more sensitive and specific.

• PDA detector is more expensive than UV detector.

• PDA detector is useful for detecting impurities while UV det...read more

UPLC stands for Ultra Performance Liquid Chromatography.

• UPLC is a technique used in analytical chemistry to separate, identify, and quantify components in a mixture.

• It is an advanced form of liquid chromatography that utilizes smaller particle sizes and higher pressures for faster and more efficient separations.

• UPLC is commonly used in pharmaceutical, environmental, and food analysis.

• It offers improved resolution, sens...read more
