Patent ID: 6867002

Claim:
A sample solution treating instrument comprising a sample treating unit and a sample supply unit, wherein the sample treating unit contains an agent that converts a sample solution to a condition for analysis with a biosensor that electrochemically measures a specific component in the sample solution, the agent selected from the group consisting of a catalyst that converts a first interfering substance in the sample solution to a harmless substance having no adverse effect on a measurement result of the specific component obtained by analysis with the biosensor, an adsorbent that adsorbs and removes a second interfering substance from the sample solution, and a buffer agent that adjusts a pH of the sample solution to a pH range adequate for an activity of an enzyme in the biosensor, and the sample supply unit is made of an elastic material that retains the sample solution inside the sample supply unit, wherein the sample supply unit is located adjacent to the sample treating unit such that the sample solution passes through the sample treating unit to the sample supply unit after treatment, but wherein the instrument is not physically coupled to a biosensor, wherein the first interfering substance and the second interfering substance may be the same or may be different.
