HPLC is a technique used to separate, identify, and quantify components in a mixture based on their interaction with a stationary phase and mobile phase.

• HPLC stands for High-Performance Liquid Chromatography.

• The principle of HPLC involves the separation of components in a mixture based on their affinity for the stationary phase and mobile phase.

• The instrumentation of HPLC includes a pump to deliver the mobile phase, a ...read more

GC stands for Gas Chromatography, a principle and instrumentation used for separating and analyzing volatile compounds.

• GC is a technique used in analytical chemistry to separate and identify components of a mixture.

• It involves injecting a sample into a gas chromatograph, which vaporizes the sample and carries it through a column.

• The column contains a stationary phase that interacts with the sample components, causing t...read more

UV spectroscopy is a technique that uses ultraviolet light to analyze the chemical composition of substances.

• UV spectroscopy is based on the principle that molecules absorb ultraviolet light at specific wavelengths.

• The Beer-Lambert law relates the concentration of a substance to the amount of light it absorbs.

• UV spectroscopy is commonly used in pharmaceutical, environmental, and forensic analysis.

• It is used to determin...read more

Molarity, molality, and normality are measures of concentration in chemistry. UV range refers to the range of ultraviolet light.

• Molarity is the number of moles of solute per liter of solution.

• Molality is the number of moles of solute per kilogram of solvent.

• Normality is the number of equivalents of solute per liter of solution.

• UV range refers to the range of wavelengths of ultraviolet light, typically between 10 and 40
