Abstract:
An organic macromolecular component analysis method comprising:providing a measurement system including a sample introduction section, a preparation section, and a measuring section; introducing a sample including an organic macromolecular component into the introduction section; transferring the sample to the preparation section; separating the organic macromolecular component from the sample; and moving the separated organic macromolecular component to the measuring section, wherein the separating comprises: adsorbing the organic macromolecular component on a resin in the preparation section; feeding an eluant solution into the preparation section; and eluting the organic macromolecular component adsorbed on the resin using the eluant solution; and further comprising introducing a mixture of the eluant solution and a phosphoric acid buffer solution into a detecting device in the measuring section wherein the phosphoric acid buffer solution is introduced into the detecting device at a flow rate of 1 mL/min or less.
