The system uses reel-to-reel filter tape sampling and nondestructive energy dispersive X-ray fluorescence (EDXRF) analysis. The air is sampled through a low volume (16.7 l/min) particulate matter size-selective inlet and drawn through a filter tape. The resulting PM deposit is then advanced into the analysis area where the sample is analyzed by EDXRF for selected metals while the next sample is collected.

FEATURES

• ADAPT data analysis software that enables immediate research quality graphical reports to deliver unique insight on the temporal and variability trends of the metals measured

• Sampling and analysis methodology that has been validated by the US EPA ETV program

• Windows-based operating system with 10.1 inch touchscreen that may be ordered flat (shown) or tilted for lower placed instruments

• Sampling, analysis, and near real-time reporting (every 15, 30, 60, 120, 180, or 240 minutes in ng/m³)

• Automatic quality assurance, alarms, & control features

• Incorporates an internal XRF quality assurance standard with every sample analyzed.

• Provides automatic, daily XRF calibration drift checks

• Remote polling and remote system control

• Global power design does not require power conversion or conditioning

• Average detection limits improved by over 30% compared to previous generation.

BENEFITS

• Adaptable to both stationary and mobile monitoring platforms
• Effective for fugitive emissions measurement
• Can be used to establish baseline levels for health-based standards
• Capable of identifying hazardous “hot spots” around the perimeter of a facility
• Enables effective source apportionment and chemical mass balance comparisons
• Highly sensitive and reliable (low pg/m3 to µg/m3 range)
• Nondestructive analysis allows for sample archiving
• Aids source identification by correlating metals concentrations to wind speed and direction
• Demonstrates metal concentration variability not observable with standard 24-hour methods
• Can be used to identify plant activities associated with high metals concentrations

APPLICATIONS

This monitoring system can simultaneously identify and measure multiple metals in ambient air to provide data for use in the following applications:

• Fence-line monitoring of metals processing facilities, incinerators, metal smelters, battery manufacturing facilities, cement plants, glass factories, and more
• Source detection of lead, arsenic, nickel, and cadmium as well as other metals
• Source Apportionment
• Determination of background concentrations
• Spatial recognition of pollution sources
• Temporal recognition of pollution sources
• Resolve acute, short duration events
• Risk and emergency management
