HPLC and GC-MS are analytical techniques used to separate, identify and quantify components in a mixture.

• HPLC stands for High Performance Liquid Chromatography and is used to separate and quantify components in a liquid mixture.

• GC-MS stands for Gas Chromatography-Mass Spectrometry and is used to separate and identify components in a gaseous mixture.

• HPLC and GC-MS are commonly used in chemistry, pharmaceuticals, and env...read more

Serial dilution is a technique used to reduce the concentration of a solution by repeatedly diluting it with a solvent.

• A small amount of the original solution is added to a larger volume of solvent

• This process is repeated multiple times to achieve the desired dilution factor

• Each dilution results in a lower concentration of the original solution

• The final concentration can be calculated based on the dilution factor and t...read more

HPLC is a chromatography technique used to separate and analyze compounds based on their polarity and interaction with a stationary phase.

• HPLC stands for High Performance Liquid Chromatography

• It uses a liquid mobile phase and a stationary phase to separate and analyze compounds

• The stationary phase can be a solid or a liquid coated on a solid support

• Compounds are separated based on their polarity and interaction with th...read more

MRL and LOQ are analytical terms used in chemical analysis.

• MRL stands for Minimum Residue Limit and is the lowest concentration of a residue that can be detected but not necessarily quantified.

• LOQ stands for Limit of Quantification and is the lowest concentration of a residue that can be accurately measured and reported.

• MRL is used to determine if a residue is present or not, while LOQ is used to determine the amount o...read more

Molar value for mobile phase can be calculated by dividing the mass of the solute by its molar mass and the volume of the mobile phase.

• Determine the mass of the solute

• Determine the molar mass of the solute

• Determine the volume of the mobile phase

• Divide the mass of the solute by its molar mass and the volume of the mobile phase
