三、其他扩展模块

扩展测量一:P515/535模块

A9Rsnhfc5_fbe5j3_7gs.jpgP515/535 模块是 WALZ 公司为 DUAL-PAM-100 设计的测量模块,可以直接连接 DUAL-PAM-100 的主机,测量 550-510 nm 的差式吸收以及 535 nm 波长的信号变化。P515/535 模块可以测量光合器官的跨膜质子动力势(pmf)、跨膜电位(Δψ)、跨膜质子梯度(ΔpH)和玉米黄素(Zea)变化等内容。此外,该模块还提供一种特殊的 “P515 Flux” 操作模式,可让光化光以光-暗脉冲形式打开-关闭(1/1调制光/暗),原位测量活体样品处于稳态的偶联电子和质子的流动速率。

扩展测量二:NADPH/9-AA 模块

NADPH/9-AA 模块是 WALZ 公司为 DUAL-PAM-100 设计的测量模块,可以直接连接 DUAL-PAM-100 的主机,测量 NADPH 荧光和 9-AA 荧光。NADPH 荧光可用于估算 NADP 的还原程度,9-AA 荧光用于估算跨膜质子梯度 ΔpH。该模块的一个很大特色是与标准探头联用,在国际上次做到了同步测量叶绿素荧光与 NADPH 荧光。

  • 可升级增加同步测量 P515/535 的功能

  

专为 DUAL-PAM-100 与 GFS-3000 的同步测量设计,由特制叶室(带温度和PAR传感器)、风扇、导光杆、电子盒与支架构成。同步测量时,光源由 DUAL-PAM-100 的测量头提供,气体交换由 GFS-3000 的红外分析器检测,P700 和叶绿素荧光由 DUAL-PAM-100 的检测器测量。

 

 

四、其他可选附件

1,Dual-DPD:单独的光电二极管检测器单元,通过导光杆连接到 ED‑101US/MD 上,配置 NADPH 模块时推荐选配。

2,Dual-DPM:单独的光电倍增管检测器单元,用于较稀的悬浮液荧光测量,需要装配到 ED-101US/MD 上使用。必须要同时配置测量头 DUAL-DB 或 DUAL-DR 来激发调制荧光。

3,ED-101US/T: 控温装置,安装在 ED-101US/MD 上,为悬浮液控温;可外接循环水浴来控温,
