X-505 XRF – At 2.75 lbs., it’s the lightest weight analyzer ever created, in a mostly metal frame for ultimate durability and duty cycle. Perfectly balanced and lightning fast – as in 1-2 seconds – you can test material all day long without fatigue. The narrow, slender form factor accesses the toughest test locations, with the latest 2.7″ (68.6mm) display for rear viewing of chemistry.
X-200 XRF – Competitively priced for every performance requirement, this platform weighs about 3.4 lbs, making it about 0.5 lbs heavier than the X-550 platform, but still with industry leading speed and precision. Updated for improved heat dissipation, reduced weight, new user-interface. All internal electronics now use less power and operate at higher temperatures—no drift or shutdown.
X-50 XRF A great value for basic analysis, PiN technology processes about 10x lower X-ray count rates than SDD, resulting in a 3x reduction of precision. However, for many RoHS/WEEE applications, the performance is satisfactory and the X-50 is available at a lower price point. Includes the same advanced X-ray tube (operating at 50 kV max.), integrated camera, video, and Android platform.
XRF is an approved analytical technique for screening various products for compliance testing, It’s the quickest and easiest way to pass/fail your products.
For RoHS, SciAps instruments comply with IEC 62321-3-1 and ASTMF2617-15, the official methods that describe procedures for the analysis of lead, cadmium, chromium, mercury and total bromine by XRF. There are additional classifications, like Green for RoHS, which means complying with RoHS as well as restricting flame retardants containing Cl, Br and Sb. SciAps software allows for the ability to add elements like Sb and adjust pass/fail levels to what the customer requires. SciAps instruments can also be used in screening for ASTM F963 compliance, an important standard for toy safety.
SciAps engineers have been solving for RoHS from the beginning, through their roles at various companies. We have decades of experience designing the next generation of instruments to meet the growing needs of this market. We bring the best possible screening program to our customers based on accuracy, efficiency and value for the customer.
Testing 4 ppm Cd with a Si Pin was unheard of a decade ago. Advancements in digital pulse processing and the extensive XRF experience at SciAps have produced the best value for money in the industry. While most instruments in the market have changed very little since RoHS or CPSIA was first introduced, SciAps newly designed software takes modern manufacturing into account.

For RoHS, Pb pass/fail requirements in a homogenous material are:
Pb for RoHS: Pass ≤ 700 – 3σ ≤ Inconclusive ≤ 1300 + 3σ ≤ Fail
The Pb action level for RoHS is 1000 ppm. Using XRF for screening, the IEC guidelines put in a 30% buffer for pass/fail that is designated as inconclusive. With XRF, you can neither say it is a pass or fail, and further analysis is required. The inconclusive range also uses the error (σ) associated with the test into expanding the inconclusive region.
For CPSIA, it is different: Pb for CPSIA: Pass ≤ 70 – 1σ ≤ Inconclusive ≤ 130 + 1σ ≤ Fail
The CPSIA action level for Pb is 100 ppm. Using XRF in accordance with ASTM F2853-10e1 and ASTM 2617-08, there are additional requirements like sample preparation and relative standard deviation of three tests to take into consideration. The extension of the inconclusive zone only uses the error reported (σ) instead of three times that amount. To pass or fail for CPSIA, none of the three tests can fall within the inconclusive zone.
Setting up a reasonable screening program allows for rapid testing of the production line. This includes examining incoming material and outgoing QC to assure compliance. While each regulation has its unique requirements for passing and failing products, XRF is a non-destructive technique, so it minimizes the disruption and cost to the product line. Take Pb as an example.
