* The information is compiled mostly from on-line descriptions of the detectors as provided by the distributors, and may be incomplete. The prices are as of January 2011 and may change at any time. REACH Devices will not be liable in any way for any loss or damage of any kind incurred as the result of the use or misuse of any information provided by, copied, or printed from this site. Customers should contact the corresponding vendors directly.

** The seemingly absurd value of 100AU arises from the fact that the Beer-Lambert law is not applicable to a nonconventional wide range flow cell (patent pending) used in these detectors. The flow cell provides various pathlengths to the incident UV beam simultaneously, so, even for the most concentrated solutions, some light still reaches the photodetector. The non-linear cell response is mathematically corrected for an ideal 1mm cell. This way, the measured OD value is still proportional to the substance concentration, even if OD exceeds 5AU.

A - Analog outputs for chart recorders and integrators. No front panel display.

B - Analog output(s) for chart recorders and integrators. Front panel display shows numerical values of absorbtion (and for some models wavelength) at the current moment.

C - Analog output(s) for chart recorders and integrators. Front panel display shows numerical values of absorbtion at the current moment. Has PC connection, specialized software is used to visualize the chromatogram.

D - Embedded color graphic display (320x240) visualizes the chromatogram, simultaneously at 250nm and at 280nm. Data can be transferred onto a standard USB flashdrive. chromatogram.
