详细介绍

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
