MODULAR Version DUAL-PAM-100

The MODULAR version of the DUAL-PAM-100 measuring system consists of the Power-and-Control-Unit DUAL-C which can be combined with various emitter and detector heads. Due to novel opto-electronic components, especially developed for the DUAL-PAM-100 measuring system, all emitter and detector units are very compact and easy to handle.

The MODULAR Version can be operated with blue or red fluorescence excitation light. When high sensitivity of fluorescence detection is required, the Photodiode Detector DUAL-DPD and the even more sensitive Photomultiplier Detector DUAL-DPM can replace the standard measuring head.

Generally, the MODULAR version provides a very flexible design of the measurement setup depending on the scientific question posed. The subsequent table compiles a number of typical measurement setup of the DUAL-PAM-100.
