What is a RoHS testing machine? Principles and applications
RoHS testing machine is a rapid analytical tool that helps businesses detect hazardous substances in electronic components, plastics, metals, and consumer products. Through this article, DC supports quality control, compliance with export standards, and adherence to environmental regulations in Vietnam.
I. Definition of RoHS testing machine
1. What is RoHS?
RoHS (Restriction of Hazardous Substances) is a directive issued by the European Union that restricts the use of hazardous substances in electrical and electronic equipment.
The objective of RoHS is to protect human health, reduce environmental pollution, and promote sustainable production and consumption.
2. What is a RoHS – compliant testing machine?
RoHS testing instrument is an analytical device used to rapidly detect hazardous substances restricted under the European Union’s RoHS Directive, in order to assess the compliance of materials, components, and electrical and electronic products before distribution or export.
This equipment enables businesses to proactively control environmental risks, meet international regulatory requirements, and enhance their ESG management capabilities.
II. Operating principles of a RoHS testing machine
1. Analysis using XRF technology
Most RoHS testing instruments today use X-ray Fluorescence (XRF) technology. When X-rays are directed onto the surface of a sample, the atoms within the material emit secondary (fluorescent) X-rays with energy levels characteristic of each element.
The detector system captures this energy spectrum in order to:
– Identify the types of elements present in the sample
– Calculate the concentration of each restricted hazardous substance

2. Comparison with RoHS standards
After collecting the XRF spectral data, the instrument’s software will:
– Process the signals and eliminate background noise
– Calculate the concentration of restricted elements
– Compare the results with the RoHS regulatory limits (e.g. Pb ≤ 0.1%, Cd ≤ 0.01%)
The results are typically displayed within seconds, allowing users to quickly and easily assess the product’s level of RoHS compliance.
III. SpectraX 30 – An ideal RoHS testing machine for businesses
1. Advanced EDXRF technology
SpectraX 30 applies advanced EDXRF (Energy Dispersive X-ray Fluorescence) technology, enabling accurate elemental composition analysis of materials.
This technology effectively detects RoHS-restricted substances such as Pb, Hg, Cd, Cr, and Br with high stability, making it suitable for inspecting electronic components, engineering plastics, and metals.
2. Dedicated RoHS software
The instrument is integrated with dedicated RoHS analysis software that supports automated data processing, clear result visualization, and direct comparison with regulatory threshold limits.
Its intuitive interface enables users to easily interpret results, effectively supporting quality control and internal inspection processes within manufacturing facilities.
3. High accuracy
Thanks to the Si-PIN detector with a resolution of 145 eV ± 5 eV, a high-resolution Be window, and an internationally standardized calibration process, SpectraX 30 ensures high accuracy and excellent repeatability across all measurements.
4. Fast, non-destructive analysis
The analysis is completed within just a few seconds to a few minutes and is completely non-destructive to the sample.
This key advantage allows businesses to test components, PCB assemblies, or finished products directly without affecting their functionality or commercial value.
5. User-friendly operation
The user-friendly design, simple operating procedure, and intuitive software make the system suitable even for first-time users.
Businesses do not require a team of specialized analysts and can proactively perform RoHS testing directly at factories or stores, saving both time and operational costs.
IV. Practical applications of RoHS testing machines
1. Electrical and electronics industry
In the electrical and electronics industry, RoHS analyzers are indispensable quality control tools used to:
– Measure the concentration of hazardous substances such as lead (Pb), cadmium (Cd), mercury (Hg), and hexavalent chromium (Cr⁶⁺) in components, PCB assemblies, cables, and connectors
– Quickly assess RoHS compliance of incoming materials and finished products
– Reduce the risk of regulatory violations when exporting to markets with strict requirements such as the EU, the United States, and Japan
Thanks to fast, non-destructive analysis, RoHS analyzers help electronics manufacturers maintain consistent product quality and optimize internal quality control processes.
2. Jewelry industry
In the jewelry and goldsmithing industry, RoHS analyzers are used to:
– Check the content of lead, cadmium, and other heavy metals in jewelry alloys
– Ensure product safety for end users, especially for jewelry that comes into direct contact with the skin
– Comply with legal requirements and safety standards when exporting jewelry to international markets
The application of RoHS testing equipment helps jewelry businesses enhance brand credibility, ensure transparency in material quality, and reduce legal and compliance risks
3. Consumer products – children’s toys
For consumer products and children’s toys, RoHS testing equipment plays a critical role in:
– Early detection of toxic heavy metals in plastics, coatings, paints, and metal components
– Ensuring consumer health and safety, especially for children who are more vulnerable to hazardous substances
– Supporting manufacturers in meeting strict product safety and environmental regulations
Applying RoHS analyzers in this sector helps businesses minimize the risk of product recalls, regulatory penalties, and loss of market trust.
