TOXY-PAM

Dual-channel Photosynthesis Yield Analyzer

The TOXY-PAM chlorophyll fluorometer is designed to detect traces of substances which act inhibitory on photosynthesis. For instance, the photosystem II inhibitor Diuron can be proved at concentrations down to
0.02 μg L−1 (Schreiber et al. (2002) Photosynth Res 74: 317-330).

The TOXY-PAM detects phytotoxic compounds by comparing the simultaneously measured photosynthetic electron transport rates of a treated and a reference sample. The outstandingly high sensitivity of the TOXY-PAM is achieved by providing absolutely identical conditions in the two parallel measuring compartments.
