X ray Fluorescence (XRF) Analyzer uses primary X rays to irradiate a sample. When high energy X rays with energy exceeding the binding energy of inner shell electrons collide with atoms, inner shell electrons are ejected, creating vacancies and exciting atoms to an unstable state. Electrons from outer shells transition inward to fill vacancies, releasing energy in the form of secondary X rays (X r
Product Description
XRF Metal Catalyst Analyzer Handheld Price XRF Analyzer
Features
* Light weight, easy carrying, high precision and high stability without destruction.
* Able to detect the content of Pd in 3s, Rh in 15s and Pt in 30s, and output the accurate data in 30s in the whole process.
* Use Si-Pin detector and high-resolution and high-count-rate SDD detector (resolution: 129ev), imported 50kv variable high-voltage X-ray tube, imported stepper motor and other core components.
* Catalyst detection limitfor SDD: 20ppm for Pt, 10ppm for Pd and 10ppm for Rh.
* The internal ceramic honeycomb structure of the catalytic converter is coated with a carrier paint containing platinum, palladium and rhodium. Additional elements can be added to the coating to enhance the performance of the catalytic converter.
* Automotive catalysts mainly contain platinum, rhodium, palladium and other precious metal elements, which are applied to purify automobile exhaust emissions.Platinum group elements recycled from automotive catalytic converters account for more than half of the market share of platinum and palladium, so is the vast majority of rhodium. In addition to accurate measurement of platinum, palladium and rhodium, it can also detect other elements that are commonly added in carrier paints. There are also some elements to be analyzed to prevent fraud. These elements are added illegally by criminals in catalysts to increase the value of precious metals.
* It has a one-key fool-proof mode to avoid complex operation options and thus effectively prevent incorrect manual operations.

Sample Preparation
First, remove the ceramic carrier from a three-way catalytic converter. Then, take the honeycomb ceramic out of the metal enclosure. Finally, collect the catalyst. Automotive catalysts consist of a ceramic body, which is largely made of cordierite and coated with platinum-containing metal. Therefore, the whole ceramic should be sorted, crushed and ground, and also often mixed with other catalysts. On the contrary, the metal-supported converter should be first crushed or ground. Then metal components and coating powder containing precious metals are separated with a magnet or by winnowing. Due to enrichment, the PGM content of the coating in the metal catalytic converter is higher than that of the ceramic converter.
In both cases, the material is crushed to a particle size of less than 250μm, followed by transfer into an XRF sample cup and analysis on a test bench.

Specification
Determination of Pt, Pd and Rh in 3-way catalytic converter of used automobile. In recent years, the composition and price of platinum group metals (PGM) such as platinum (Pt), palladium (Pd) and rhodium (Rh) in three-way catalytic converters fluctuate more than ever before, which has increasing impact on the purchase, trading and recycling of used three-way catalytic converters.
For a single catalytic converter, the price of PGM components may be less than $100 or greater than $1,000. These materials are usually ground into powder and then mixed for trading. Therefore, businesses and recyclers should be able to:1. Identify catalytic converters or mixtures with high platinum group metal content;
2. Trading at a reasonable price;
3. Identify whether the mixture contains fake or inferior substances.It is critical to determine the platinum, palladium and rhodium content in catalytic converters of used automobiles in real time, thus maximizing profits and avoiding considerable economic losses.
