ElvaX PmX-5050: Precious Metals Analysis

The Growing Threat of Airborne Heavy Metals

Why Monitor Metals in Air?

Airborne heavy metals in particulate matter pose serious health risks even at low levels. They persist in the environment, accumulating in soil, water, and organisms. Exposure causes respiratory issues, cardiovascular disease, neurological damage, and cancer.

Key metals of concern:

1. Lead (Pb): neurological damage, especially in children
2. Cadmium (Cd): carcinogenic, kidney and bone damage
3. Arsenic (As): cancer and cardiovascular risks
4. Chromium (Cr VI): carcinogenic
5. Nickel (Ni): respiratory sensitizer, potential carcinogen
6. Copper (Cu), Zinc (Zn), Manganese (Mn): toxic at high levels

Traditional filter sampling gives delayed results — by the time data arrives, pollution episodes are over and intervention is impossible.

Regulatory Drivers

Strict limits exist worldwide:

1. EU Air Quality Directive: annual limits for Pb, Ni; monitoring for As, Cd, Hg
2. US EPA: NAAQS for lead; air toxics monitoring for additional metals

Compliance requires reliable, timely data. Violations lead to enforcement, restrictions, and heavy penalties.

Revolutionary Continuous Monitoring Technology

How ElvaX PmX-5050 Works

The ElvaX PmX-5050 is a fully automated, unattended air monitoring station:

1. Continuous air sampling draws ambient air through filter tape, collecting PM10/PM2.5 particulates.
2. At set intervals (typically hourly), tape advances to position sample for XRF analysis.
3. High-energy X-rays excite metals; high-resolution SDD detector quantifies 15–20 elements simultaneously.
4. Results transmit automatically in real-time to data systems, agencies, and networks.
5. System runs 24/7 without intervention, advancing fresh tape for continuous cycles.

This automation provides real-time data impossible with manual sampling and lab analysis.

Advanced XRF Technology

• High-sensitivity SDD detector for excellent energy resolution and peak separation at trace levels.
• Optimized X-ray source with automatic filter selection for light and heavy metals.
• Temperature stabilization ensures consistent performance in varying outdoor conditions.
• Advanced algorithms correct for matrix effects, filter loading, and particle size variations.

Comprehensive Multi-Element Analysis

Simultaneous Detection of Multiple Metals

The ElvaX PmX-5050 measures 15–20 elements per cycle, including:

Priority Toxic Metals

• Lead (Pb)
• Cadmium (Cd)
• Arsenic (As)
• Chromium (Cr)
• Nickel (Ni)
• Mercury (Hg)

Additional Elements

• Copper (Cu)
• Zinc (Zn)
• Manganese (Mn)
• Iron (Fe)
• Titanium (Ti)
• Vanadium (V)
• Cobalt (Co)
• Selenium (Se)
• Bromine (Br)

This multi-element data enables complete air quality profiling and pollution source fingerprinting.

Detection Limits and Accuracy

Detection limits reach low ng/m³ range:

• Lead: 1–5 ng/m³
• Cadmium: 0.5–2 ng/m³
• Arsenic: 0.5–2 ng/m³
• Nickel: 1–3 ng/m³

Sensitivities meet strict regulatory standards, with accuracy validated against reference lab methods.

Real-Time Data for Immediate Action

Hourly Measurements vs. Daily Averages

Traditional 24-hour sampling hides short pollution spikes. ElvaX PmX-5050 provides hourly data, revealing:

• Diurnal patterns (traffic, industry, weather)
• Short high-concentration episodes
• Pollution source timing
• Meteorological correlations
• Fast emergency response

This turns monitoring from historical records into real-time intelligence.
