Q2. Types of HPLC columns
Ans. 
HPLC columns are used in High Performance Liquid Chromatography to separate and analyze compounds in a sample.
• Types include reversed-phase, normal-phase, ion-exchange, size-exclusion, and affinity columns

• Reversed-phase columns use a non-polar stationary phase and are commonly used for separating hydrophobic compounds

• Normal-phase columns use a polar stationary phase and are used for separating polar compounds

• Ion-exchang...read more

Q4. Solubility types
Ans. 
There are three main types of solubility: miscible, immiscible, and partially miscible.
• Miscible: substances that are completely soluble in each other in all proportions (e.g. ethanol and water)

• Immiscible: substances that do not dissolve in each other (e.g. oil and water)

• Partially miscible: substances that are partially soluble in each other (e.g. acetone and water)

Q1. What is hplc and what is used for detector calibration?
Ans. 
HPLC is a technique used in chemistry to separate, identify, and quantify components in a mixture. Detector calibration ensures accurate measurement.
• HPLC stands for High-Performance Liquid Chromatography.

• It is used to separate and analyze components in a liquid mixture.

• HPLC utilizes a stationary phase and a mobile phase to separate the components based on their interactions.

• The detector in HPLC measures the concentrati...read more

Q3. What is buffer solution
Ans. 
A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added.
• Consists of a weak acid and its conjugate base, or a weak base and its conjugate acid

• Maintains a stable pH

• Used in various chemical and biological applications

• Example: Acetic acid and sodium acetate buffer solution

Q4. What is pH meter use electrodes
Ans. 
pH meter electrodes are used to measure the acidity or alkalinity of a solution.
• pH meter electrodes are typically made of glass or special plastics.

• The electrodes are immersed in the solution being tested, and generate a voltage that is proportional to the pH of the solution.

• The pH meter then converts this voltage into a pH reading, which indicates the acidity or alkalinity of the solution.

• Regular calibration and maint...read more
