警告
有毒、易燃及有害溶剂、样品及试剂
处理溶剂、样品和试剂可能会危害健康安全。
- 从阀头取出溶剂时，确保溶剂不会从接头滴出。
- 处理这些物质时，请严格遵循溶剂供应商提供的材料处理和安全数据表中的相应安全规程（例如，戴上护目镜、安全手套，穿上防护衣）。
小心
阀损坏
在高压侧使用低压阀可能会使阀损坏。
- 当使用多个柱温箱作为方法开发解决方案的一部分时，请确保高压阀头连接到自动进样器，低压阀头连接到检测器。
小心
柱损坏或测量结果偏差
将阀切换到错误位置可能会使柱损坏，或使测量结果发生偏差。
- 使叶片与凹槽配合可确保将阀切换到正确位置。
小心
阀驱动包含敏感光学部件，需要防尘和防止其它污染。若这些部件遭污染，可能会降低阀口选择的精确性，从而使测量结果发生偏差。
- 运行和存储时请务必安装阀头。为保护阀驱动，可使用模拟阀头（ G1316-67001 (运输锁工具包) 的一部分）替代实际工作阀头。切勿接触阀驱动内部部件。
注意
For details, please refer to the Agilent InfinityLab LC 方法开发解决方案用户指南 (InfinityLab-Method-Development-Solution-UseMa-en-SD-29000211.pdf, SD-29000211).
注意
The tag reader reads the valve head properties from the valve head RFID tag during initialization of the module. Valve properties will not be updated, if the valve head is replaced while the module is on.
Selection of valve port positions can fail, if the instrument does not know the properties of the installed valve.
注意
To have the valve correctly recognized by the valve drive you must have the valve drive powered off for at least 10 seconds.
-
Push the valve head for bringing it to its outer position (column compartment only).
-
Remove all capillary connections from the valve head.
Unscrew the nut and remove the valve head.
Put the new valve head onto the valve drive such that the lobe fits to the groove (see also G7116B_Installation of the Valve Heads ).
Fasten the valve head onto the valve drive using the union nut (see also G7116B_Installation of the Valve Heads .
Install all required capillary connections to the valve head.
Push the valve head until it snaps in and stays in the rear position (column compartment only).
