Lead Based Paint (LBP) Analysis using DELTA Handheld XRF

The DELTA Tube Based Handheld XRF with the new, proprietary SmartScreen™ method for LBP measurements provides fast and accurate analysis of lead (Pb) in paint without radioactive isotopes.

Fast, Accurate Handheld XRF with New SmartScreen™ Method*

For LBP testing, the DELTA XRF with SmartScreen™ adjusts speed of measurement for optimum accuracy and maximum productivity. Most tests take less than 3 seconds. Even the longest tests are typically less than 10 seconds.

The absolute sensitivity for the DELTA tube based - SDD technology on surface coatings and materials, based on a 120 second test time, is 0.1μg/cm2 or 0.0001mg/cm². Although many other conditions exist, the table below gives precision data in the context of residential Pb paint testing - where the action levels are typically in the 1.0mg/cm² range and testing times are often less than 10 seconds.

For most paint matrices, whether positive or negative for Pb, SmartScreen™ can deliver a rapid, accurate result. However, when SmartScreen™ identifies a challenging paint matrix through spectral analysis, it extends the measurement time as required for greater accuracy and analytical confidence.

Tube Based LBP Inspections No Radioactive Isotopes

• DELTA handheld XRF analyzers use X-ray tube sources, unlike radioactive isotope sources which are known to be slower and fade over time, requiring frequent resourcing or factory recalibrations.
• The X-ray tube output of a DELTA remains constant for testing with the same precision and speed for its entire life; it starts fast and stays fast.
• X-ray tube based analyzers are much less likely to report false LBP positives than radioactive isotope based analyzers when the Pb is actually in a solid structure, for example on the far side of a wall or door.
• X-ray tube based analyzers eliminate business liabilities associated with owning hazardous radioactive isotopes.
• DELTA handheld XRF analyzers are reliable, light-weight, and ergonomically designed. Optionally available dust wipe, filter, and soil analysis add-on capabilities can help expand business opportunities to other environmental safety inspections without having to purchase a second analyzer.
• The overall low total cost of ownership is a benefit with the DELTA handheld XRF - no resourcing, no biannual leak tests, no radioactive disposal costs, and no increased testing time with age.
