How to choose rohs testing instruments?

Published on:2025-04-21

Choosing a suitable RoHS testing instrument requires a comprehensive consideration of factors such as testing requirements, budget, sample type, and regulatory requirements. The following are the key steps and points to help you make a reasonable choice:


1. Clarify the testing requirements
Target elements: Six hazardous substances restricted by RoHS 1.0 (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers), as well as four new phthalates added by RoHS 2.0 (DEHP, BBP, DBP, and DIBP).

Detection range: Is it necessary to cover all 10 substances? Or only for specific elements?

Sample type: Solid materials (such as plastics, metals), liquids (such as inks, coatings) or complex components (such as circuit boards)?



2. Understand common RoHS testing technologies
Select the appropriate method based on accuracy, speed and cost:

Technical type applicable elements advantages and disadvantages Typical equipment
XRF (X-ray Fluorescence) is non-destructive, rapid and portable for heavy metals such as lead, cadmium, mercury and chromium, but it cannot detect Br (bromine) or phthalates. Handheld/desktop XRF
ICP-OES/MS all heavy metals (with high precision) and high sensitivity require sample pretreatment for quantitative analysis and are large-scale laboratory equipment with high costs
GC-MS/ Thermal cracking of complex pretreatment and time-consuming laboratory-specific equipment for precise detection of organic compounds such as phthalates and polybrominated biphenyls
3. Purchasing channels

Online e-commerce platforms: such as B2B platforms like Alibaba

Factory direct sales: Contact the manufacturer of the testing instrument directly

Agent channel: Purchase through regional agents

4. Budget and Brand
Domestic brand (100,000-200,000 yuan) : Pyrolysis solution (Representative brand: Hongsheng)

Imported brands (> 500,000 yuan) : A complete ICP-MS + GC-MS solution (Representative brands: Shimadzu, Agilent).



5. Certification and After-sales Service
Certification requirements: Does the instrument comply with ISO 17025 or IEC 62321 standards?

After-sales service: Is the response time for maintenance, calibration service, and supply of consumables convenient?
