DUAL-DPD

The DUAL-DPD is used when fluorescence levels of suspensions are too low to be accurately detected by the DUAL-DB or DUAL-DR heads. Compared to the two latter units, the DUAL-DPD detector is about tenfold more sensitive permitting measurements down to concentrations of 5 µg Chl/L using the blue modulated excitation light of the DUAL-DB head. Normally, the DUAL-DPD is mounted on the ED-101US/MD optical compartment right-angled to the DUAL-DB or DUAL-DR head.
