- Q1. What is tha pH?
- Ans.
pH is a measure of the acidity or alkalinity of a solution.
pH stands for 'potential of hydrogen'.
It is a logarithmic scale ranging from 0 to 14.
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.
pH is determined by the concentration of hydrogen ions in a solution.
Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9.
- Q2. PH presens of hydrogen in sample .
- Ans.
PH represents the concentration of hydrogen ions in a sample.
PH is measured on a scale of 0-14, with 7 being neutral.
A lower PH indicates higher acidity, while a higher PH indicates higher alkalinity.
PH can be measured using a PH meter or through chemical indicators.
The PH of a sample can affect its chemical properties and reactions.
- Q3. What is lod and difference between lod and water.
- Ans.
LOD stands for Limit of Detection. It is the lowest concentration of a substance that can be reliably detected.
LOD is used to determine the sensitivity of an analytical method.
It is usually expressed as a concentration or mass.
Water is a chemical compound composed of hydrogen and oxygen, while LOD is a term used in analytical chemistry.
LOD is important in environmental testing to determine the presence of contaminants ...
- Q4. Lod is loss on drying to determine the volatile impurities and the water is dtermination of presens of moisture and water molecules in sample

(2 Questions)
- Q1. What is pH meter , How to calibrate pH meter
- Ans.
A pH meter is a scientific instrument used to measure the acidity or alkalinity of a substance. Calibration ensures accurate readings.
pH meter measures the concentration of hydrogen ions in a solution
Calibration involves adjusting the pH meter to known standard solutions
Regular calibration ensures accurate readings over time
- Q2. Explain the parts of HPLC
- Ans.
HPLC stands for High Performance Liquid Chromatography, which consists of a pump, injector, column, detector, and integrator.
HPLC involves a pump to push the liquid solvent through the system.
It includes an injector to introduce the sample into the mobile phase.
The column separates the components of the sample based on their interactions with the stationary phase.
A detector measures the amount of analyte in the eluent.

(2 Questions)
- Q1. What are the buffer used in HPLC
- Ans.
Buffers commonly used in HPLC include phosphate buffers, acetate buffers, and citrate buffers.
Phosphate buffers are commonly used in HPLC for separating acidic compounds.
Acetate buffers are used for separating basic compounds.
Citrate buffers are used for separating metal ions.
Other common buffers used in HPLC include ammonium acetate and ammonium formate.
- Q2. How to calibrate HPLC
- Ans.
HPLC calibration involves adjusting parameters to ensure accurate and reliable results.
Prepare standard solutions of known concentrations
Run the standard solutions through the HPLC system
Compare the results to expected values and adjust parameters as needed
Repeat the process until accurate and consistent results are obtained
