X-505 XRF Analyzer

Harmony of performance, ergonomics and price

The SciAps X-505 is the smallest, lightest weight handheld X-ray analyzer ever made. In terms of speed, it is second only to the X-550. Weighing in at 2.8 lbs. with the battery, it delivers the small size, blazing speed and high precision of the SciAps X Series in a perfectly balanced device. It’s fast on all alloys, including aluminums. With its state-of-the-art design and excellent heat handling, the X-505 can run all day long, even in the hottest climates, without requiring down time due to overheating.



Delivers PMI for most alloys in 1 second with excellent precision

2.98 lbs with battery - The vast majority of PMI work is for common stainless, Cr-Mo steels, low alloy steels and high temperature alloys such as nickel, titanium, and cobalt based alloys, superalloys and specialty alloys such as tungsten carbides, tin-lead solders, zirconium alloys and many more. The X-505 verifies grade and chemistry in 1-2 seconds with excellent precision.

Residuals in the Alloy App

Measure Ni, Cr and Cu content down to 0.01-0.02% to verify the sum of the three elements is less than 0.15%. And also meet the latest requirements that V and Nb both be < 0.02%.

Sulfidic Corrosion in the Alloy App

Combined with highly optimal internal geometry, the X-505 measures silicon in steels below 0.1% for sulfidic corrosion applications.

Scrap Processing

A major advancement for aluminum alloy sorting. The historic weakness of X-ray has been aluminum alloy sorting. This is because most X-ray guns are poor at measuring magnesium (Mg), and Mg analysis is critical to correctly sorting aluminum alloys. The X-505 was designed for optimal sensitivity to Mg, and therefore silicon (Si). The result is an analyzer that offers accurate sorting of the many complex grades of aluminum alloys.  See our Guide to Aluminum Alloy Sorting

Great on high temp alloys and precious metals.

Like most XRFs, the -505 provides fast, precise chemistry on the wide array of high temperature alloys, stainless, red metals and precious metals

Tramps Elements

Scrap processing has moved beyond just grade sorting. Many consumers now demand analysis on tramp or residual elements in common steel, nickel and copper alloys. The X-505 is optimized for low detection limits on common tramp elements, including Cr, Ni, Cu, V, Nb, Mo in steels, Pb and Bi in nickel alloys, and various undesired elements in copper alloys.


Now available for exploration and ore grade control applications. Contact us for details about our elemental analysis for exploration and pathfinder applications. SciAps XRF analyzers are utilized worldwide by many major exploration companies and mining laboratory services companies.  Also available with compact test stand for closed-beam operation.


The X-505 may be equipped with elemental analysis of environmental soils. The analysis package includes the 8 RCRA metals and 11 of the 12 EPA priority pollutant metals (except beryllium – use our Z-903 LIBS for that). The X-505 complies with the long standing EPA Method 6200.

RoHS Applications

The X-505 will soon be available with our RoHS and Halogen-Free apps, offering fast, precise analysis of the RoHS elements Pb, Cd, Br, total Cr and Hg, plus Cl for halogen-free requirements.

General Analytical

Do you have a unique analytical applications? The X-505 can be equipped with our Empirical App, allowing the user to set up unique beam conditions, define specific elements of interest and create custom calibrations. For analytical requirements outside the realm of alloys, ores and polymers, the X-505 plus Empirical App offers complete flexibility for unique or proprietary analytical requirements.

A brief comparison: X-550 vs. X-505

What’s the difference between the premium X-550 and the workhorse X-505 models?  The answer is simple: Speed on low atomic number elements such as Mg, Al, Si, P and S. The X-550 runs at about 3x the X-ray power in the “Beam 2” setting (also known as the low voltage setting) compared to the X-505 or other handheld XRF analyzers.  This means the measured intensities from Mg, Al, Si, P and S (plus K, Ca and Cl in other apps) are 3x higher, producing 3x faster measurements. A few common examples are shown below

Measure 0.3% Mg in aluminum alloy
2 seconds
7 seconds
For example, sorting Al 356 from 357.
Measure 0.1% Si in steels
6 seconds (1s Beam 1; 5s Beam 2)
16 seconds (1s Beam 1; 15s Beam 2)
Sulfidic corrosion, requires Si > 0.1% in steels.
Measure P and S in steels or stainless
For a given concentration level, about 3x faster than X-505.
Actual test times depend on the specific concentration level of P and S.
Analyze low atomic number elements in mining samples
Measures Mg, Al, Si, P, S, Ca and K 3x faster than X-505.
Measures these elements well, with comparable speeds to other high-end XRFs.
X-550 offers faster test times for major metals, sulfides and contaminant P.
