典型应用
HLD3 的应用由注射器计量与阀选路共同决定。一个注射器可依次连接多个液源或目标端口，适合多步骤液体处理；需要重点管理共享流道中的残留。
多试剂分析：顺序选路与定量分配
分析流程可能依次使用试剂、稀释液和清洗液。旋转阀先选择所需液源，注射器取液后再连接目标路径完成排液。这一组件可称为多端口注射泵（multi-port syringe pump）或试剂分配模块（reagent dispensing module）。
应根据实际阀流路图确定可连接的液源与排液方向，并计算共享注射器和管路的置换量。不同试剂间切换时安排冲洗，避免仅靠切换端口就认为液路已清洁。
样本前处理：稀释液定量添加
向已知样本量中加入规定体积的稀释液，属于稀释加液（diluent dispensing）。设备可能将其称为稀释泵或配液模块，但稀释倍数仍取决于样本量、稀释液量及后续混合，而不是单独由泵名称决定。
HLD3 可按目标液量选择注射器，并在设备控制中定义吸液补充、排液和混合步骤。较小容量的注射器可作为小液量任务的候选，实际性能应按工作行程验证。
方法切换：共享液路的置换与残留控制
在不同试剂共用注射器的分析流程中，切换端口后仍可能残留上一种液体。让清洗液流过共享路径称为冲洗（flushing）；正式工作前将液路充满、排除空气称为预充（priming）。两者都涉及走液，但验收目标分别是残留水平和充液状态。
HLD3 可按已确认的阀流路选择清洗介质与排放路径。清洗方法应覆盖注射器、公共流道、输出管与针头；用空白液检查高浓度液体之后的携带污染（carryover），再确定清洗顺序和用量。
应用选型信息
请提供液源和输出路径数量、所需阀流路图、单次加液量、试剂与清洗介质、允许残留和背压，再确认注射器容量、端口配置与通讯方式。
