GL
Sciences – Electrochemical Detector (ED703)
Features
- Wide
working potential window, low background current and high reproducibility
- A
conductive diamond is used as a working electrode in the detector
- Easy
maintenance
- The
activity of diamond electrodes can be regenerated while online
without disassembling the flow cell and polishing the electrode
when applying a high potential of +5.0 V vs. Ag/AgCl. This is
a specific advantage of diamond electrodes and allows reliable
and reproducible results.
- Long
operating life
- The
sp3 carbon in the diamond structure and the inertness of the diamond
surface results in long operating life.
- Standard
equipment of cell oven
- The
cell oven is fitted in the detector as a standard equipment. Extremely
high reproducibility is obtained because of constant flow cell
temperature.
Evaporative
Light Scattering Detector (ELSD)
Chromachem
The Chromachem
is the most flexible evaporative light scattering detector integrating
high level of sensivity with lower evaporation temperature for both
nebulizer and evaporation chambers.
The detector works as a stand alone unit or fully controlled by external
devices through its RS232.

-
Universal
detection of non-volatile compound
-
Ideal
for lipids, carbohydrates, polymers, pharmaceuticals and compounds
with weak chromophores
-
Compatible
with HPLC gradient
-
More
stable and sensitive than RI
-
Low
temperature operation even with water at high flow rate
-
Response
factors less variable than RI, UV and MS
CHROMACHEM
technology:
Light
Scattering Detection has a technique which can detect any sample
less volatile than the mobile phase used for the chromatographic
separation.
Sensitivity is at least 20 times higher than RI detector and
comparable, on the average, with UV detection.
