- Q1. How to identify the samples for analysis
- Ans.
Samples can be identified based on labeling, appearance, unique characteristics, and accompanying documentation.
Check the labeling on the sample containers for identification information such as sample name, ID number, and date collected.
Examine the physical appearance of the samples, noting color, texture, and any visible impurities.
Look for unique characteristics such as odor or solubility that can help differentiate...
- Q2. What is nmr spectroscopy
- Ans.
NMR spectroscopy is a technique used to study the structure and composition of molecules by analyzing the magnetic properties of atomic nuclei.
NMR spectroscopy involves applying a magnetic field to a sample, which causes the nuclei of certain atoms to resonate at specific frequencies.
The resulting signals are detected and used to create a spectrum that provides information about the chemical environment of the nuclei.
N...
- 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
- Q5. Why silica gel is used as stationary phse
- Ans.
Silica gel is used as a stationary phase in chromatography due to its high surface area and ability to interact with a wide range of compounds.
Silica gel has a high surface area, allowing for better separation of compounds based on their interactions with the stationary phase.
It can interact with a wide range of compounds, making it versatile for different types of chromatography techniques.
Silica gel is chemically ine...
- 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.
An exampl...
- Q7. What is isomerism
- Ans.
Isomerism is a phenomenon in which two or more compounds have the same molecular formula but different structural arrangements.
Isomers have different physical and chemical properties.
Types of isomerism include structural isomerism, stereoisomerism, and conformational isomerism.
Example: Structural isomers - butane and isobutane.
Example: Stereoisomers - cis and trans isomers of 2-butene.
- Q8. The same molecular formula but different structure are Present inthe spease

- 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...
