Water Removal System | Teledyne 651 manual

Technical Description

Teledyne API Ultrafine Particle Monitor - Model 651

The Inlet Pressure reading is displayed on the Status screen on the front-panel display.

Water Removal System

The Model 651 has a water separator and ejection system to remove water from the vapor stream exiting the optics assembly. The water separator condenses the water vapor and then the collected water is ejected through the WATER EXHAUST port on the back panel and away from the internal flow control orifices. A drain tube or bottle is provided to allow the small amount of expelled water to be directed away from the instrument to a suitable drain.

The Model 651 has a lower detection curve with a D50 of 7 nm. D50 is defined as the particle diameter at which 50% of particles are detected. The curve fit shown in Figure 6-1 is based on testing of three Ultrafine Particle monitors using sucrose particles generated by TSI Model 3480 Electrospray Aerosol Generator and size- classified with TSI Model 3080 Electrostatic Classifier and Model 3085 Nano Differential Mobility Analyzer (DMA). The counting efficiency is calculated by comparing the Model 651 readings to TSI Model 3068A Aerosol Electrometer readings.

The particle concentration measured by the particle counter is the total number concentration of all particles that the Model 651 can detect. This measurement provides no size differentiation and it is not corrected using the Model 651 counting efficiency curve.

The Model 651 has a fast response time. T95, defined as the time it takes for the instrument reading to reach 95% of a concentration step change, is < 1.0 sec. Figure 6-2 shows the response time curves, based on the average of three Ultrafine Particle monitors.
