Overview

GRIMM 130 PAH detector 130 particle bound PAH detector for real-time detection of particle bound polycyclic aromatic hydrocarbons

Product Details

Basic concepts of instruments

This kind of smallPAHThe sensor can be integrated into any of our existing dust monitor housings (as shown in the figure below, #)165 FG）Alternatively, it can be used in conjunction with portable monitors to replace external filtering elements.

The air sample, air flow rate, and power supply are supplied by the dust monitor. Measurement data is accessibleRS-232Obtained through a single line interface or analog output terminal. The latter two interface methods can be used for data storage, and107Instrument data storage card and "environmental monitoring instrument software" are used for monitoring.

orRS-232The interface can provide more detailed measurement data and allow configuration and remote controlPAHSensors. In addition to meteorological sensors, this highly sensitive sensor can be integrated with our indoor air quality monitors or environmental sensorsPM10andPM2.5The monitor is used together as a particle species determination sensor.

Application scenarios:

In addition to the particle size distribution of fine particles, continuous measurementsPAHData is very important information that helps determine the content of volatile compounds in the atmosphere.

Therefore, the following locations were measuredPAHConcentration can provide better information about heating and burning different fossil fuels in places such as:

* Roadside;

* Forest and industrial fires;

* Wood burning;

* Tunnels, subways, and so on

The following image shows a busy traffic intersectionPAHDaily concentration changes.

Measuring principle

Measurement principle: Particle bindingPAHPhotoionization effect.

PAHSensors can qualitatively measure the concentration of polycyclic aromatic hydrocarbons bound to particles.PAHSensors use excimer lamps to charge particles through photoelectric action, and these particles will be collected on a filter. Use an electrostatic meter to measure charge flow. This can relatively measure the binding of particlesPAHConcentration, or through appropriate calibration, can be measured more accuratelyPAH.PAHSensors can qualitatively measure allPAHThe concentration is faster and more cost-effective than traditional measurement methods such as filtration extraction and corresponding gas chromatography-mass spectrometry analysis. However,PAHSensors cannot distinguish each individual type separatelyPAHThe concentration.
