Air Quality Monitoring

0108 Airlogics.png

AirLogics offers ambienbt air quality monitoring services to clients who wish to: 

  • Manage risk associated with potential off-site migration of airborne contaminants, site constituents, odor, and/or emissions. 

  • Establish baseline or background air quality in a neighborhood or on a work site.

  • Measure or improve their indoor air quality. 

The “CLASSIC” 2.0 SYSTEM

The AirLogics “Classic” 2.0 is our most robust monitoring system and can measure the following parameters in real-time:

Compound-specific VOCs (via a robust field GC)
Our portable field gas chromatographs (GC) measure compound-specific volatile organic compound (VOC) concentrations in real time.  The GCs can be configured to operate in either a total volatile organic compound (TVOC) mode or in a compound specific mode (i.e., benzene).  In the TVOC mode, if the TVOC level exceeds a pre-determined value, the GC switches to a compound-specific analysis to identify the individual compounds.  

 

Particulates (i.e., dust)
Our direct-reading, real-time particulate, or dust, meters monitor dust using infrared electromagnetic radiation to sense airborne particles.  The dust meter can be configured to respond to dust particles < 10 micron in diameter (PM10), < 2.5 microns (PM2.5) in diameter, or to a total suspended particulate (TSP) value.

Weather
The AirLogics on-site meteorological tower measures wind speed, direction, dry-bulb temperature, and relative humidity. The central computer system receives continuous information from the meteorological tower and computes a two-minute running average wind speed and direction value.  This, in turn, is used to identify which monitoring station is upwind, downwind, or crosswind.

NEW & IMPROVED!

The AirLogics Monitoring Systems

AirLogics offers a variety of equipment, detailed below, with specifications to satisfy virtually every project need or compliance requirement. Our highly qualified and experienced staff will help you determine which system will work best for your site.

While AirLogics leases our equipment, our business model is not simply “rent & go” (i.e., we don’t just drop-off the equipment and leave.)  We provide full support for AirLogics equipment, help you manage robust data management and visualization platforms, and assist with the data collection and interpretation to the degree you choose.  We also provide the on-going maintenance and calibration as required.  Depending on the client’s preference and the equipment deployed, we also provide on-site personnel to operate our equipment on a turn-key basis.  

 

SolarLite

The AirLogics SolarLite system is solar-powered, and therefore more flexible than the Classic. It differs from the “Classic” in that it does not provide compound-specific VOC analysis, but it does measure the following parameters in real time:

Total VOCs (via a PID)
VOCs are measured utilizing portable photoionization detectors (PIDs).  The PIDs indicate total organic compounds without differentiation of individual compound concentrations. The limit of detection is 10 parts per billion by volume (ppbv). 

Particulates (i.e., dust)
Like the AirLogics “Classic,” the particulate meter on the SolarLite system detects  dust by using infrared electromagnetic radiation to detect dust particles < 10 micron in diameter (PM10), < 2.5 microns (PM2.5), or detect a TSP value.  

Dust monitoring can effectively be used as a surrogate for other compounds, such as polyaromatic hydrocarbons (PAHs)
       
Weather
The SolarLite weather tower has the same capabilities as the one installed on the Classic, but the SolarLite system operates on solar power. It is configured with an on-board battery backup and a data logger allowing up to 12 hours of continuous recording in the event of power interruptions.

 

AQS-1 and DUST SENTRY 

AQS-1 and the Dust Sentry are AirLogics’ newest and most nimble, modular, and customizable air monitoring systems. 


•    Real-time total VOCs (PID)

•    Dust (PM2.5, PM10, TSP)
•    O3, NO2, noise.
•    Gravimetric sampling capabilities
•    Light-weight lithium battery, solar power charging,
      or 110-power option
•    Integrated weather station 
•    Light, mobile system

Key technology unique sets the AQS 1 apart in the industry:  

Pumped sampling system. This provides a steady flow of air to the sensor modules. It also allows for the use of filters which protect the sensors from airborne impurities – therefore extending their operating life.

Automatic Baseline Correction (ABC).  This technique sees the automatic correction of the ‘zero’ baseline every 60 seconds. The technique corrects for cross interferences and sensor drift – two of the biggest problems for sensor-based monitors.

Tried and tested PM sensing. A nephelometer made by Met One Instruments and custom-designed for the AQS 1. Compared to low cost optical counters, the Met One nephelometer is robust and proven to last for years in the field. In the AQS 1 the nephelometer is coupled with a pumped sampling system and an inlet heater which corrects for humidity interference.

Factory and Field Calibration. The AQS 1 sensor modules are calibrated against high purity gas standards prepared under ISO 6143 to ensure traceability to reference materials from National Metrology Institutes. The AQS 1 is field calibrated using the same standard reference materials as a US EPA / EU certified analyzer (i.e. calibration gas and dilution calibrators).
 

AQS-1.jpg

This equipment uses a proven near forward light scattering nephelometer and high precision sharp cut cyclone – with a measurement range of 0-60,000 μg/m3.  

The patented sensor technology enables the AQS 1 to deliver data with very strong correlation to U.S. EPA approved monitors (Near Reference) over extended periods of time – several years with appropriate maintenance.  In head-to-head tests with traditional U.S. EPA-approved analyzers, the AQS 1 has shown R2 correlations as high as 0.98.

TSP SAMPLER

A total suspended particulate (TSP) sampler, or TSP high volume air sampler, is used for the collection of TSP matter in ambient air with no preference to size selection. The US EPA reference method for the collection of TSP is called out in 40 CFR 50, appendix B.  The TSP high volume air sampler collects particulate at a flow rate between 39-60 ft/³min over a constant sampling period.  The TSP high volume air sampler is used to determine the concentration of total suspended particulates or it can be used to determine the identity of the particulates.

 

TSP high volume air samplers come in a variety of configurations.  The basic system is composed of an anodized aluminum outdoor shelter with a gabled roof assembly.  It will include a timing device to turn the instrument on and off, a filter holder to hold the filter media in place, a vacuum motor, a device to control the flow, a pressure recorder to record the flow rate, and an elapsed time indicator to count the sample time.
