Centaur Pharmaceuticals Analyst Interview Questions and Answers

UV, IR, KF, and polarimeter are analytical instruments used for different types of analysis based on principles of light absorption, emission, and rotation.

• UV (Ultraviolet) spectrophotometer measures the absorption of ultraviolet light by a sample to determine its concentration or purity.

• IR (Infrared) spectrophotometer measures the absorption of infrared light by a sample to identify functional groups in organic compou...read more

Calibration of analytical balance is essential for accurate measurements in analytical chemistry.

• Calibration involves comparing the readings of the balance to known weights.

• Regular calibration ensures accuracy and reliability of measurements.

• Adjustments may be needed if the balance readings deviate from the known weights.

• Calibration should be done using a proper calibration weight and following manufacturer's instructi...read more

PH range is 0-14. Calibration ensures accuracy by adjusting the PH meter to known standards.

• PH range is from 0 to 14, with 7 being neutral

• Acidic solutions have a PH below 7, while alkaline solutions have a PH above 7

• Calibration involves adjusting the PH meter using buffer solutions of known PH values

• Regular calibration ensures accurate PH measurements

Molarity of HCl is a measure of concentration of hydrochloric acid in a solution.

• Molarity is defined as the number of moles of solute per liter of solution.

• To calculate molarity, divide the number of moles of solute by the volume of the solution in liters.

• For example, if you have 0.5 moles of HCl in 1 liter of solution, the molarity would be 0.5 M.
