Fluorometer chlorophyll
WebThe PAM-2500 chlorophyll fluorometer is an extremely compact and powerful measuring system. All optical and electronic components are located in a 23 cm x 10.5 cm x 10.5 cm housing. Different from previous portable PAM fluorometers, high-performance LEDs are employed for saturation pulses permitting quasi-rectangular light intensity changes.

Fluorimetry is widely used by the dairy industry to verify whether pasteurization has been successful. This is done using a reagent which is hydrolysed to a fluorophore and phosphoric acid by alkaline phosphatase in milk. If pasteurization has been successful then alkaline phosphatase will be entirely denatured and the sample will not fluoresce. This works because pathogens in milk are killed by … http://otronix.com/index.php/product/opticsensor/?board_name=OPTIC_SENSOR04&order_by=fn_pid&order_type=desc&vid=13
