Thermionic Ionization Sources (Beads)
- Supplier: DET
Product Description
- Durable cylindrical ceramic structure with a heater wire core, and mounted on a hexagonal shaped flange. Pre-tested for response. Interchangeable in Agilent 6890/7890 NPD assemblies, and in all DET detector assemblies.
- TID-1 - Selective response to nitro-compounds, some halogenates, oxygenates especially phenols and carboxylic acids, chains of Methylene groups, and other electronegative functionalities - operates at 400 - 600oC in inert (N2) or oxidizing (air, O2) gas environments - femtogram detection for compounds like methyl parathion, 4-nitrophenol, pentachlorophenol, heptachlor, 2,4-dinitrotoluene, TNT, and acetaldehyde-DNPH when powered with -45 Volt polarization available from a DET Current Supply.
- TID-2 - Selective response to N,P compounds - Black Ceramic coating has long life and minimal tailing of phosphorus compounds - operates at 600 - 800oC in a dilute H2 in air gas environment - low picogram detection for NP compounds - lower cost alternative to Agilent NP sources.
- TID-3 - Selective response to volatile halogenates - more uniform response to halogenates than TID-1 - operates at 600 - 800oC in inert (N2) or oxidizing (air, O2) gas environments - low picogram detection for trihalomethanes with minimal peak tailing and greater response for Br versus Cl - powered with -45 Volt polarization from a DET Current Supply.
- TID-4 - Our best coating for selective detection of N compounds (not recommended for P compounds because of tailing) - operates at same NPD conditions as TID-2 with 2 to 3 times better N detection than TID-2.
- TID-5 - Halogen selective detection - more uniform response than TID-3 - operates at same temperatures and gas environment conditions as TID-2, but with a higher polarization voltage (-45 V) available from a DET Current Supply - provides exceptional selectivity for Br versus Cl when configured with a stoichiometric H2/air mixture.
- TID-6 - P selective detection with suppressed N response - uses much higher Hydrogen, Air, and Nitrogen flows than the TID-2 and TID-4 NPD modes.
- TID-7 - NEW Green Ceramic for halogenated pesticides, PCBs - operates in N2, Air, or O2
