Dual-PAM/F: Dual-PAM-100的光纤版,适合野外使用
Schreiber教授因发明PAM系列调制叶绿素荧光仪而获得首届国际光合作用协会(ISPR)创新奖
2006年正式商业化的双通道PAM-100荧光仪——DUAL-PAM-100,是大名鼎鼎的PAM-101/102/103的升级版,是全球唯一可同步测量P700(PS I活性)和叶绿素荧光(PS II活性)的仪器,短短两年多时间里在全世界科研界得到广泛应用,发表了数十篇高水平科研论文。

受光电技术限制,DUAL-PAM-100的测量头DUAL-DB(或DUAL-DR)和DUAL-E都是外置的,仪器不方便在野外使用。2009年,Schreiber教授及其团队经过两年的不断研发、改进,终于做到在不损失信号的基础上将所有的激发光源和检测器内置到主机中,推出了光纤版双通道PAM-100荧光仪——DUAL-PAM/F

DUAL-PAM/F采用光纤做为激发光、叶绿素荧光和P700信号的传导体,方便在野外现场测量P700和叶绿素荧光,朝着P700的现场测量迈出了一大步!

主要功能* 野外或室内单独或同步测量叶绿素荧光和P700
* 两个光系统的诱导动力学曲线(包括快相和慢相)
* 两个光系统的快速光曲线和光响应曲线
* 淬灭分析、暗驰豫分析
* 典型的P700曲线测量
* 通过叶绿素荧光和P700的同步测量获知两个光系统的电子传递动力学、电子载体库的大小、围绕PSI 的环式电子传递动力学等

应用领域
相当于两台PAM-101/ 102/ 103的功能,可同时测量光系统II活性(调制叶绿素荧光)和光系统I活性(P700吸收变化)可用于光合作用机理研究、植物生理学、农学、林学、园艺学等领域,特别适合于野外现场测量。

测量参数
PS II参数:Fo, Fm, F, Fm’, Fv/Fm, Y(II)=△F/Fm’, Fo’, qP, qL, qN, NPQ, Y(NPQ), Y(NO)和ETR(II)等
PS I参数:P700, Pm, Pm’, P700red, Y(I), Y(ND), Y(NA)和ETR(I)等

主要技术参数
* P700双波长测量光:LED,830 nm和870 nm
* PSII荧光测量光:LED,460 nm(DUAL-DB)或620 nm(DUAL-DR)
* 红色光化光:LED阵列,635 nm;zei大连续光强2000 μmol m-2 s-1
* 蓝色光化光:LED,460 nm;zei大连续光强700 μmol m-2 s-1
* 单周转饱和闪光(ST):200000 μmol m-2 s-1,5~50 μs可调
* 多周转饱和闪光(MT):20000 μmol m-2 s-1,1~1000 ms可调
