GC Detectors - DET Thermionic Detectors (TID)

direct from the Inventor of TSD and TID

DET Products -  2006 Aust Prices PDF 10p 3mb

multiple modes of detection (NPD, PTID, TID-1, TID-3, TID-5, FTID, FID, Remote FID, Tandem TID)
unique selective responses to hetero-atom compounds
( Nitrogen, Phosphorus, Oxygenates, Halogenates, Nitro-compounds, Lead, Tin, Silicon )

inexpensive, easy to operate equipment (most modes do not require high purity detector gases)
DETECTORS for GAS CHROMATOGRAPHY - hardware designed to custom fit onto the existing FID or NPD base on various GC models (e.g., Agilent 6890, HP 5890, Varian 3800, SRI 8610)

CERAMIC ION SOURCES (Beads) FOR THE NPD (Nitrogen-Phosphorus Detector)
AND OTHER TID (Thermionic Ionization Detector) MODES,
INCLUDING REPLACEMENTS FOR THE AGILENT 6890 NP ION SOURCE

STAND-ALONE TRANSDUCERS and DETECTION MODULES

Examples of some applications:

• drugs of abuse with NPD (TID-4).

• pesticides and environmental pollutants with NPD (TID-2 or TID-4).

• nitro explosives with TID-1 and NPD (TID-4).

• phenols and carboxylic acids in foods and flavors analyses with TID-1.

• oxygenates and N-compounds in petroleum samples with TID-1 and NPD.

• Pb or Sn in complex matrices with REMOTE FID and organic-fueled flame.
