HPLC SOLVENT DELIVERY SYSTEM 高压液相溶剂传输系统
The following tests are proposed for the periodic and motivated check of the HPLC solvent delivery system: flow rate and gradient test.
以下测试作为HPLC溶剂传输系统周期性主动检查:流速和梯度检查
FLOW RATE 流速
Materials: 材料

Mobile phase: degassed water 流动相:脱过气的水 No column (open end)* 无柱(开放式)*
Flow rate: adjusted between 0.5 and 3.0 ml/min 流速:调节在0.5到3.0ml/min
If high-pressure mixing systems are installed, this test has to be done on each solvent channel.
如果有安装高压混合系统,本测试应在每一溶剂通道进行。
* For certain equipment, e.g. in the case of low flow rates, the check would be performed by using a column or a backpressure regulator.
* 对于一定的仪器,例如,流速较低时,采用一根柱子或背压调整器进行检查
Method方法:
Set the flow rate at an appropriate level and measure the time needed to fill the volumetric flask up to the mark. Record the time needed.
将流速设定在一个合适的水平,测量将容量瓶装满至刻度的时间。记录所用的时间。
