- Q1. What is meant by Gas chromatography
- Ans.
Gas chromatography is a technique used to separate and analyze volatile compounds in a mixture.
Gas chromatography involves the use of a stationary phase and a mobile phase.
The stationary phase is a solid or liquid coating inside a column, while the mobile phase is a gas.
The mixture is injected into the column, and as the mobile phase flows through, different compounds interact with the stationary phase at different rat...
- Q2. Which buffet solution is used for ph meter calibration
- Ans.
Buffer solutions with known pH values are used for pH meter calibration.
Buffer solutions with pH values of 4.01, 7.00, and 10.01 are commonly used for pH meter calibration.
The choice of buffer solution depends on the pH range of the sample being tested.
The buffer solutions should be stored properly and replaced regularly to ensure accurate calibration.
Calibration should be performed before each use of the pH meter.

- Q1. Basic analytics instruments releted.
- Q2. What is the length of gc column
- Ans.
The length of GC column varies depending on the type and manufacturer.
GC columns can range from 10-100 meters in length.
The length of the column affects the separation of compounds.
Longer columns provide better separation but require more time and may have higher costs.
The length of the column should be chosen based on the specific analysis needs.
Different types of columns may have different optimal lengths.
- Q3. What is the length of HPLC coloumn
- Ans.
The length of HPLC column varies depending on the application and type of column used.
The length of HPLC column can range from 30 mm to 300 mm.
Shorter columns are used for faster separations while longer columns are used for higher resolution.
The length of the column can also affect the retention time of the analyte.
For example, a C18 column with a length of 150 mm is commonly used for routine analysis of pharmaceutica
- Q4. Difference between HPLC and gc
- Ans.
HPLC and GC are both analytical techniques used to separate and analyze compounds, but they differ in their principles and applications.
HPLC stands for High Performance Liquid Chromatography, while GC stands for Gas Chromatography.
HPLC is used for separating and analyzing compounds that are soluble in liquid, while GC is used for separating and analyzing compounds that are volatile and can be vaporized.
HPLC uses a liqu...

- Q1. What is chromatography ?
- Ans.
Chromatography is a technique used to separate and analyze mixtures of substances based on their different properties.
Chromatography involves a stationary phase and a mobile phase.
The stationary phase is a solid or liquid material that retains the components of the mixture to be separated.
The mobile phase is a liquid or gas that carries the mixture through the stationary phase.
Different components of the mixture intera...
- Q2. What is 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.
Each unit change in pH represents a tenfold change in acidity or alkalinity.
pH is commonly used in various fields such as chemistry, biology, and environmental science.
- Q3. What is nitration reaction ?
- Ans.
Nitration reaction is a chemical reaction in which a nitro group (-NO2) is introduced into a molecule.
Nitration is a type of electrophilic aromatic substitution reaction.
It involves the substitution of a hydrogen atom on an aromatic ring with a nitro group.
The reaction is typically carried out using a mixture of nitric acid and sulfuric acid as the nitrating agent.
Nitration reactions are commonly used in the synthesis ...

- Q3. What is the ph and its definition
- Ans.
pH is a measure of acidity or alkalinity of a solution on a scale of 0 to 14.
pH stands for 'potential of Hydrogen'
It measures the concentration of hydrogen ions in a solution
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline
Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9
- Q4. How to identify the ranges in nmr and uv
- Ans.
Ranges in NMR and UV can be identified by analyzing the chemical shifts and absorption peaks, respectively.
In NMR, chemical shifts are measured in parts per million (ppm) and can range from 0 to 12 ppm for proton NMR.
In UV spectroscopy, absorption peaks are observed at specific wavelengths, typically ranging from 200 to 400 nm.
Interpreting the peaks and shifts in the spectra can help determine the functional groups pre

- Q6. What is oxidation and reduction
- Ans.
Oxidation is the loss of electrons by a molecule, atom, or ion, while reduction is the gain of electrons.
Oxidation involves the addition of oxygen or loss of hydrogen, while reduction involves the loss of oxygen or gain of hydrogen.
Oxidation increases the oxidation state of a molecule, while reduction decreases it.
An example of oxidation is the rusting of iron, where iron reacts with oxygen to form iron oxide.

- Q7. What is isomerism
- Ans.
Isomerism is a phenomenon in which two or more compounds have the same molecular formula but different structural arrangements.
