CERAMIC ION SOURCES (Beads) for the NPD (Nitrogen-Phosphorus Detector) and OTHER TID (Thermionic Ionization Detector) MODES, INCLUDING REPLACEMENTS for the AGILENT 6890/7890 NP ION SOURCE (Highest Quality, Best Performance, Lowest Cost, Unlimited Shelf Life). A  family of different ceramic coatings provides an easy change from one mode of selective detection to another using the same basic equipment. An ENVIRONMENT FRIENDLY RECYCLING OF DEPLETED  ION SOURCES is available for any DET, Agilent, Thermo, SRI, or other brand NPD.

NEW - CATALYTIC COMBUSTION IONIZATION METHOD for the selective detection of METHYLENE functional groups in Petroleum, Biodiesel, and FAME samples with differentiation between saturated and unsaturated Carbon bonds.

DETECTORS for GAS CHROMATOGRAPHY - hardware designed for custom retrofit onto the existing FID or NPD base on various GC models (e.g., Thermo Trace, Agilent 6890, Varian 3800, SRI 8610, HP5890) - features a concentric cylinder geometry for stream-lined gas flow and optimum ion collection efficiency - (NEW combination of DET Hardware and versatile Thermo Trace NPD Electronics provides unrivaled interchangeable capability for all modes of NPD and TID detection).

COMPACT GC for SELECTIVE DETECTION of OXYGENATES & NITRO COMPOUNDS or NITROGEN-PHOSPHORUS COMPOUNDS (NPD) - inexpensive, portable size size GC features novel thermionic detection techniques, 0.32 mm fused silica column, and simple interchangeability from one detection mode to another.
