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.
DELTA XRF SmartScreen™ 3-σ Precision
| Pb Concentration | 0.3 mg/cm2 Pb in Paint | |
| LBP Sample Type | Surface |
Buried
(12 layers of blank paint) |
| 3 seconds test | 0.053 | 0.08 |
| 10 seconds test | 0.03 | 0.04 |
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.
