1. a cleaning method for the sample cell of Water Test Kits, described Water Test Kits comprises:

  • Flow channel switching valve, multiple ports that described flow channel switching valve is had a public port and can be communicated with described public port by switching;

    Liquid feeding device, described liquid feeding device is communicated to the public port of described flow channel switching valve;

    Sample cell, described sample cell is communicated to one in described multiple port of described flow channel switching valve;

    AndAnalyrical reagent container, described analyrical reagent reservoir is to another in described multiple port of described flow channel switching valve;

    It is characterized in that, described cleaning method comprises the following steps;

    A. with pure water, described sample cell is cleaned;

    B., after described cleaning completes, described flow channel switching valve switches to the state that port that described analyrical reagent container is communicated with is communicated with described public port, and described liquid feeding device sucks analyrical reagent;

    C. described flow channel switching valve switches to the state that port that described public port is communicated with described sample cell is communicated with, and the described analyrical reagent sucked is injected described sample cell by described liquid feeding device;

    D. make described analyrical reagent in described sample cell, stop predetermined time after discharge;

    E., after described discharge, described sample cell is again cleaned with pure water.
