As a special service to all OC-Sensor users Eiken Chemical Co.Ltd. offers a unique quality comparison (EQCS OC).

Once a year all of the OC-Sensor laboratories are invited by Eiken to participate in a round robin test. The EQCS OC programme has developed into one of the biggest inter-laboratory comparisons,  consisting of over 1,000 participating laboratories worldwide, and in this form is unique to FIT.

For this quality comparison, two control materials (dissolved in buffer solution) with unknown concentrations of haemoglobin, are sent every year to the participating laboratories for analysis using their respective OC-Sensor devices. The data is collected by Eiken and evaluated before publishing to the participating laboratories.
