Dr. Reddy's 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

UV stands for ultraviolet and its principle involves electromagnetic radiation with a wavelength shorter than that of visible light.

• UV radiation is divided into UVA, UVB, and UVC based on their wavelengths.

• UV radiation is commonly known for its effects on skin, such as sunburn and skin cancer.

• UV radiation is also used for disinfection purposes, such as in water treatment and sterilization.

The pH of water is typically around 7, which is considered neutral.

• The pH scale ranges from 0 to 14, with 7 being neutral, below 7 acidic, and above 7 basic.

• Pure water has a pH of 7, but this can vary due to dissolved minerals or gases.

• Acidic water has a pH below 7, while basic water has a pH above 7.
