#SRI-8690-1026

SRI GC DETECTORS - DELCD - DRY ELECTROLYTIC CONDUCTIVITY DETECTOR

• Non-radioactive alternative to ECD
• High sensitivity - detection levels down to 10ppb
• Selective to chlorinated and brominated compounds
• Use with headspace or purge and trap injectors
• Can be combined with FID, NPD and TID detectors
• Includes spare detector cell

The DELCD is much like the ECD in sensitivity, but it is much more selective to halogens and blind to oxygen. The SRI DELCD differs from the traditional wet ELCD in that it uses neither a solvent electrolyte nor a nickel reaction tube, and the reaction products are detected in the gaseous phase. In the high sensitivity mode (no hydrogen, using dry cylinder air) the DELCD can detect down to the low picogram range. In this mode, the DELCD is about 100 times more sensitive than the FID/DELCD. However, the high sensitivity DELCD is susceptible to contamination from high concentrations of chlorinated hydrocarbons and hydrocarbon solvents.

HOT TIP:

Up to six detectors can be mounted on the 8610c gc mainframe.
