Just What Does the EPA Say?

In a recent EPA Performance Evaluation “ … there were significant differences in instrument performance with respect to the objectives; these differences in performance reflect the variations in instrument components, operation, and calibration. In general, instruments with more established procedures and quantitation algorithms for analysis of environmental samples performed the best.…Sample throughput was higher and per sample costs were lower … due to shorter instrument run times and simplified sample handling procedures.… Thus, the analysis of multiple elements is substantially less expensive … [and] … can easily provide rapid-turnaround data in the field to aid in-field decision-making and more cost-effective environmental cleanup.”

Key Innov-X Performance Points of the Evaluation Include:

• Cadmium (Cd) Analysis: Innov-X was rated superior for Cd LOD performance – 20-50ppm
• Accuracy for Cd Analysis: Innov-X has the best accuracy for Cd (RPD<10%)
• Limits of Detection, General: Innov-X had better detection limits for As, Cu, Pb, Hg, Se, and Zn
• Precision on RoHS Elements: Innov-X is more precise on more of the RoHS elements: Pb, Cd, Hg all in the RSD<5% range (And As for China RoHS Regs)

The Innov-X Handheld XRF meets EPA Method 6200 for metals in soil, NIOSH Method 7702 for lead in air filters, and OSHA Methods OSSA1 and OSS1 for lead in air filters and dust wipes. The 8 RCRA Metals and Priority Pollutant Metals are easily monitored on-site, in real-time with Innov-X Handheld XRF.
