T/CAIA YQ002-2016 Liquid microflow testing method
Basic Information
Scope
Scope: This standard specifies the test methods for the output error and repeatability of liquid micro-flow, and is applicable to the performance testing of micro-flow output devices such as infusion pumps and precision micro-injection pumps used in liquid chromatographs. This standard is applicable to liquid measurements in the micro-flow range of 0.1 μL/min to 1000 μL/min using pure water as the medium. Main technical content: Mass method (First method): Using pure water as the liquid medium, the mass of pure water output by the liquid micro-flow output device within a unit time is measured by a precision electronic balance, and the output error and repeatability of the flow rate are calculated. Flowmeter method (Second method): Using pure water as the liquid medium, the outlet of the liquid micro-flow output device is connected to the inlet of the flowmeter, and the micro-flow is measured in real time online. The flow data are collected and a flow curve is drawn, and the output error and repeatability of the flow rate are calculated.
