水样荧光仪Water-PAM

schreiber教授因发明pam系列调制叶绿素荧光仪而获得首届光合作用协会（ispr）创新奖

利用调制叶绿素荧光技术，测量野外自然水体或培养的微藻样品的光合作用（叶绿素荧光诱导加淬灭分析、光响应曲线等），也可测量叶绿素含量，是进行野外光合作用研究的良好工具。除了测浮游植物外，可扩展探头测量附着藻类或大型藻类。除了取水样到样品杯中测量外，可扩展探头进行水下原位、连续测量，特别适合于连续监测海洋、湖泊、水库、河流等水体的叶绿素含量以及光合活性。

功能：
1）可单机操作，可连接电脑操作
2）可测叶绿素荧光诱导曲线并进行淬灭分析
3）可测光响应曲线和快速光曲线（rlc）
4）可测量水样的量子产量（光合效率）和相对电子传递速率（光合速率）
5）51个内置模式菜单，方便参数设置和标准测量
6）灵敏度高，检测限为0.1 μg l^-1 chl
7）三种配置：
系统i用于浮游植物研究；系统ii用于附着藻类和大型藻类研究；系统iii用于连续监测水体光合作用
8）主机为通用控制单元pam-control，可扩展为microscopy-pam和microfiber-pam
