Lead Based Paint (LBP) Analysis using DELTA Handheld XRF


DELTA SmartScreen

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.

*The DELTA does not have a HUD PCS; therefore, it is not suitable for HUD LBP applications.

Productos para la aplicación
Este modelo de analizador portátil DELTA permite medir plomo (Pb) en cuestión de segundos. Estas unidades fiables, dotadas con tubos de rayos X, son ligeras y presentan un diseño ergonómico para efectuar análisis durante todo el día. Los analizadores ofrecen rapidez en sus inicios y permanecen así durante toda su vida útil, evitando la disipación de isótopos. Asimismo, ofrecen un bajo costo (Esp. coste) total de propiedad. Antes de iniciar la reparación de su estructura/material (p.ej., esmerilado, corte o pintura) monitorice los niveles de plomo (Pb); e, incluso, verifique su área de trabajo después de la limpieza.
El DELTA Professional, dotado de un detector de deriva de silicio (SDD) de gran superficie y tubo de rayos X avanzado de 4W, proporciona un rendimiento superior en términos de velocidad, límites de detección y escala de elementos. Analiza elementos que van desde el magnesio (Mg) hasta elementos superiores en aleaciones y minerales. Este analizador representa la mejor solución de la serie de analizadores DELTA de Olympus.
