詳細介紹

schreiber教授因發(fā)明pam系列調(diào)制葉綠素熒光儀而獲得首屆光合作用協(xié)會(ispr)創(chuàng)新獎

利用調(diào)制葉綠素熒光技術(shù),測量野外自然水體或培養(yǎng)的微藻樣品的光合作用(葉綠素熒光誘導加淬滅分析、光響應曲線等),也可測量葉綠素含量,是進行野外光合作用研究的良好工具。除了測浮游植物外,可擴展探頭測量附著藻類或大型藻類。除了取水樣到樣品杯中測量外,可擴展探頭進行水下原位、連續(xù)測量,特別適合于連續(xù)監(jiān)測海洋、湖泊、水庫、河流等水體的葉綠素含量以及光合活性。

功能

2)可測葉綠素熒光誘導曲線并進行淬滅分析
3)可測光響應曲線和快速光曲線(rlc)
4)可測量水樣的量子產(chǎn)量(光合效率)和相對電子傳遞速率(光合速率)
5)51個內(nèi)置模式菜單,方便參數(shù)設置和標準測量
