The type of GC detector refers to the specific technology used to detect and quantify analytes in gas chromatography.

• Common types include flame ionization detector (FID), thermal conductivity detector (TCD), electron capture detector (ECD), and mass spectrometry (MS)

• FID is sensitive to organic compounds, TCD is non-destructive and universal, ECD is selective for electron-capturing compounds, MS provides mass spectra fo...read more

The type of GC column refers to the material used to separate compounds in gas chromatography.

• GC columns can be made of different materials such as silica, polyethylene glycol, or bonded phases like phenyl or cyano.

• The choice of GC column depends on the compounds being analyzed and the desired separation efficiency.

• For example, a non-polar column like a 5% phenyl methyl siloxane column is suitable for analyzing hydroca...read more

The type of titration refers to the method used to determine the concentration of a substance in a solution.

• Common types include acid-base titrations, redox titrations, and complexometric titrations.

• In acid-base titrations, a pH indicator is often used to determine the endpoint.

• Redox titrations involve the transfer of electrons between reactants.

• Complexometric titrations are used to determine the concentration of metal...read more

LOD is a method to determine the amount of water in a substance, while Karl Fischer is a specific titration method for measuring water content.

• LOD stands for Loss on Drying and is a method used to determine the moisture content in a substance by measuring the weight loss after drying.

• Karl Fischer titration is a specific method used to accurately measure the water content in a sample by titrating it with a Karl Fischer ...read more

The type of column in HPLC is typically a stainless steel tube filled with silica particles.

• Common types include C18, C8, and C4 columns

• Columns can vary in length, diameter, and particle size

• The choice of column depends on the analyte being separated
