——The insertion of aspiration tube in the flow-cell is relatively deep, and pulls it out slightly.
8) The aspirate volume of flow Flow-cell is not constant. ——Check whether aspiration tube is blocked.
——Peristaltic pump tube may be changed.
9) Quality control is not within the target value range. ——Check the valid date of reagent.
——Check whether the settings are correct, and whether it need revise parameters.
——Make sure quality control is not polluted.
——Measure again with other methods.
——Check flow flow-cell, and use the other reagent and quality control to measure again.
Note: Instruments of different versions may have slight changes. All these changes are performed on the premise of not affecting the functions and operation of instrument, consumers can take it easy to use it.
