Analytical Chemistry Technical Report

[Chromatography Q & A] What solvents are used for washing and storage after using the column?

Most of the HPLC columns currently used are commercially available packed columns packed with packing agents. In this case, the solvent filling the column at the time of release needs to be replaced w...

[Chromatography Q & A] Which buffer solution is used for the HPLC mobile phase?

A mixture of water and organic solvents is often used for the mobile phase of HPLC. However, when the dissociation state of the target component changes depending on the pH, the pH should be kept cons...
