- Q1. What is resolution?
- Ans.
Resolution refers to the ability of a system to distinguish between two closely spaced objects or points.
Resolution is a measure of the clarity or sharpness of an image produced by a camera or display.
It is often expressed in terms of pixels for digital images or lines per millimeter for optical devices.
Higher resolution results in more detailed and clearer images.
For example, a camera with a resolution of 12 megapixel...
- Q2. What type of standard used in AAS?
- Ans.
The standard used in AAS is the atomic absorption standard.
Atomic absorption standard is used to calibrate and validate the accuracy of AAS instruments.
It helps in determining the concentration of elements in a sample by measuring the absorption of light at specific wavelengths.
Common examples of atomic absorption standards include solutions of known concentrations of elements like copper, lead, and zinc.
- Q3. What is the principal of HPLC?
- Ans.
HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.
HPLC involves a stationary phase (usually a column packed with particles) and a mobile phase (liquid solvent).
The sample mixture is injected into the HPLC system and carried by the mobile phase through the column.
Different components in the sample interact differently with the stationary ...

- 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 distillation ?
- Ans.
Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point.
The vapor is then condensed and collected as a separate liquid.
This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants.
Examples include the distillation of alcohol to ma...
