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...read more

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.

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 ...read more

Q1. Principal ofHPLC
Ans. 
HPLC is a technique used to separate, identify, and quantify components in a mixture based on their interactions with a stationary phase and a mobile phase.
• HPLC involves pumping a sample mixture through a column packed with a stationary phase, where different components interact differently and are separated based on their affinity for the stationary phase.

• The separated components are detected as they exit the column a...read more
