Nano Quantity Analyte Detector

Quant Technologies' newest product represents a major advancement in high performance liquid chromatography detection capability. The Nano Quantity Analyte Detector () detects a broad range of semi- or non-volatile analytes, with or without a chromophore. Its high sensitivity allows measurement of compounds down to low nanogram levels. It offers a wide dynamic range and superior linearity when compared to other aerosol-based detectors. The is available from Quant Technologies. [more]

Water Condensation Particle Counters
Quant Technologies has developed a growing line of continuous laminar-flow Water Condensation Particle Counters (WCPC) to measure the number concentration of submicrometer sized particles in air. Applications include environmental monitoring, atmospheric and climate research, health studies, nanotechnology, combustion research, and clean room/contamination monitoring. These WCPCs are distributed exclusively by TSI Incorporated, a renown name in aerosol measurement instrumentation. To learn more about these WCPCs, please contact TSI.

LiquiTrak Nonvolatile Residue Monitor
Another new development employs the same WCPC core technology to measure residue after evaporation in ultrapure water systems.  Ultrapure water is sprayed into a fine mist of droplets that are heated and dried leaving behind an ultrafine aerosol of the nonvolatile residue impurities. The ultrafine residue aerosol is then detected optically using a WCPC. The Liquitrak® Nonvolatile Residue Monitor (NRM) is exclusively marketed by Fluid Measurement Technologies, Inc., (FMT) a company specializing in the microelectronics and pharmaceutical industries.  For more information about the NRM, please contact FMT.  Patents pending. LiquiTrack is a registered trademark of Fluid Measurement Technologies, Inc.

Patented Growth Tube Technology
Quant Technologies LLC has exclusive rights to a patented new technology for applications to measure the number concentration of very small airborne particles. These particles are often too small to be detected using conventional optical scattering or electrical methods. The patented technology employs a novel “growth tube” used to encapsulate small airborne particles into water droplets, thereby enlarging their size for easy detection.

Here’s how it works. A laminar flow aerosol stream is continuously fed into the growth tube. The growth tube employs warm wetted walls held at an elevated temperature relative to the aerosol flow. Because the mass diffusivity of water vapor exceeds the thermal diffusivity of air, the flux of water vapor to the centerline is faster than the heat flux from the walls. This difference produces a maximum supersaturation along the centerline of the flow. Particles as small as a few nanometers in diameter act as condensation sites for the supersaturated water vapor. The particles grow through condensation and are then easily counted with an optical detector.
