Abstract

The present invention quickly resolves troubles in an analyzer and performs effective external quality control management. An analyzer (2) and a control device (1) are connected by a network (3). Error data and sample data taken from an assay of a quality control substance are transmitted from the control device (1) to the analyzer (2). The analyzer (2) is made to be remotely operable from the control device (1) and when problems arise, repair from the control device (1) is possible. The control device (1) tallies sample data and provides the tally results to a Web page. The analyzer (2) accesses the Web page using a WWW browser, and it can perform external quality control in real time.
