Accessories for MINI-PAM-II: O₂ + Fluorescence Configuration
The FSO2-II package consists of an oxygen meter with optical sensor (“optode”, also called “optrode”). Together with the FSO2-AK interface, photosynthetic oxygen evolution and PAM fluorescence analysis can be performed in parallel. The oxygen-responsive element of the optode is a luminescent dye whose light emission is quenched by oxygen. The optode technology excels by its long-term stability of calibration, small dimension, oxygen-free operation, and fast response time (< 3 s, 90% signal change).
The currently available configuration permits combined oxygen and fluorescence measurements with suspensions. The setup for suspensions requires the cuvette KS-2500 which provides ports for the oxygen sensor and the MINI-PAM-II fiberoptics. In addition, the MKS 2500 stirrer ensures effective mixing during measurements.
Setup for simultaneous chlorophyll and oxygen measurements. The oxygen sensing part of the system (FSO2-II1) consists of a FireStingO2 oxygen meter and an optical oxygen sensor (optode). The oxygen meter is connected by an interface (FSO2-AK) to the MINI-PAM-II. The MINI-PAM-II fiberoptics and the oxygen sensor are inserted in a KS-2500 Suspension Cuvette which is placed on a MKS-2500 Magnetic Stirrer with Fiberoptics Holder. Constant temperature in the KS-2500 Suspension Cuvette is achieved by a water bath, which is not part of delivery.
