SciAps Handheld XRF Analyzer X-550
The premium standard for portable XRF — ultralight, blazing fast, and the most articulate XRF gun ever made.
At 2.98 lbs., the SciAps X-550 handheld XRF analyzer delivers alloy grade and chemistry in 1–2 seconds. Its class-leading 50 kV, 500 µA tube runs 3× the light-element power of a standard XRF — so even magnesium, aluminum, and silicon resolve fast.
One Analyzer, Endless Possibilities
Every X-550 is the same 2.98 lb. analyzer on the same Android platform.

X-550 Geochem
The next level for geochemistry
The X-550 Geochem adds an external cooling fan for high duty cycles in extreme heat, plus the innovative 3-Beam Geochem App that uses three separate tube excitation conditions to analyze more elements at the best possible detection limits. Advanced algorithms combine Compton Normalization and Fundamental Parameters for the best analytical performance regardless of element or matrix.
- Beam 1 (40 kV) — transition and heavy metals: Ti–Bi, plus U, Th.
- Beam 2 (10 kV) — major metals and light elements: Mg, Al, Si, P, S, K, Ca.
- Beam 3 (50 kV) — pathfinders and light REEs: Ag, Cd, Sn, Sb, Te, Ba, La, Ce, Pr, Nd, Sm.
- 13-beam X-ray tube — 40 kV Rh · 10 kV · 50 kV Au
- 2External cooling fan — −10°C to 50°C, continuous
- 340+ elements — FP + Compton algorithms
- 43.15 lbs. — With battery

Where the X-550 goes to work
Frequently Asked Questions
How fast does the SciAps X-550 sort aluminum?
The X-550 measures magnesium down to 0.25% in about 2 seconds using its patented Aluminum App, so it separates aluminum grades that differ only by chemistry — like 3003/3004 or 356/357 — where slower guns force a downgrade or a 20-second test.
Is the X-550 Pb lead paint analyzer radioactive?
No. The X-550 Pb uses an X-ray tube, not a radioactive isotope, and holds accepted HUD PCS at all three action levels (1.0, 0.7, 0.5 mg/cm²) with no inconclusive range — eliminating isotope replacement, disposal, and licensing.
What is Detector Protector Technology on the X-550?
DPT is a rigid, fine-grid, high-strength window that prevents the detector punctures common when jamming an analyzer into turnings. It's standard on X-550 units with the Alloy App, and across 1,000+ DPT units in the field, not one detector has been punctured.
Should I buy the X-550 or the X-505?
Choose the X-550 for the fastest aluminum sorting, the lowest P/S test times, or lead-paint capability. Choose the X-505 for the same transition/heavy-metal precision at a lower price when a few extra seconds on light elements is acceptable.
Get Both With OneBox
Pair the X-550 with a SciAps Z-Series LIBS and cover every element and sample type — same batteries, cables, chargers, and accessories. LIBS analyzes what XRF can't (Li, Be, B, C, F, Na); XRF is great for transition and heavy metals.
