1. Introduction to the RoHS Directive

2003 February 2: Directive of the European Parliament and of the Council on the restriction of the use of certain hazardous substances in electrical and electronic equipment

(The Restriction of Hazardus Substances in Electrical and Electronic Equipmenr (RoHS) Directive (2002/95/EC) is in force for public use.

After August 2005, 8, the recycling system and the disposal and cost payment system of waste electrical and electronic products must be put into operation, and the directive must enter into force as the law of the Member States.

After July 2006, 7: In principle, electrical and electronic products containing the six classes of hazardous substances restricted by the RoHS directive will not be allowed to enter the EU market.

The hazardous substances restricted in the RoHS Directive are: harmful heavy metals: lead (Pb), mercury (Cd), cadmium (Cd), hexavalent chromium (Cr6+) Harmful organic compounds: PoltBrominated Biphenyls, Polybrominated Diphenyl Ethers

2. Response plan

As a leader in scientific instruments in the field of inorganic and organic pollutant detection - TexPro Instruments ensures that your products meet the requirements of environmental protection laws, including the requirements of the EU RoHS and WEEE directives.

The RoHS and WEEE Directives, which came into full force in July 2006, will severely restrict the use of cadmium, lead, mercury and hexavalent chromium, as well as brominated flame retardants such as polybrominated biphenyls (PBBs) and polybrominated phenyl ethers (PBDEs) in electrical and electronic products. At the same time, the Directive also follows other regulations aimed at environmental protection issues, such as EU Directive 7/76/EEC, which lists 769 hazardous substances and substance classifications.

Ceppo understands the profound implications of the RoHS Directive and is aware of the challenges and financial burdens of many electrical and electronic equipment manufacturers, their supply chains, and consumers in implementing the instructions. In its current grim form, companies that manufacture, distribute or sell equipment to the EU are called upon to determine whether restricted substances are present in their products and, if so, within acceptable concentration ranges. At present, global electrical appliance manufacturers have established their own product quality management programs to make their products comply with the regulatory requirements of the RoHS/WEEE Directive.

To help enforce global environmental protection laws, Spectrum Instruments provides relevant analytical tools, including instruments, consumables, software and technical support; To support compliance with the RoHS/WEEE directive, we offer full-spectrum direct-reading inductively coupled plasma emission spectrometers (ICP-OES), atomic absorption spectrometers (AAS), ultraviolet-visible spectrophotometers (UV-Vis) for the separation of cadmium, lead, mercury, hexavalent chromium, and gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) for the analysis of polybrominated biphenyls and polybrominated diphenyl ethers.

Analysis of hazardous substances is prohibited

The RoHS/WEEE directive prohibits the use of cadmium and its compounds, lead and its compounds, mercury and its compounds, hexavalent chromium compounds

Chemical Standard/Test Reference Test Instruments

Cadmium and its compounds EN1122, 91/338/EEC atomic absorption spectrometer or ICP-OES

Lead and its synthesis US EPA3052, 3051A atomic absorption spectrometer or ICP-OES

Mercury and its compounds US EPA3050B atomic absorption spectrometer or ICP-OES

Hexavalent chromium compound US EPA3060A&7196A UV-Vis spectrophotometer

Polybrominated biphenyls and PBDEs 76/769/EEC, 83/264/EE gas chromatography-mass spectrometry

Complex and important sample preparation

Lead and its compounds: microwave digestion wet digestion method, nitric acid, hydrochloric acid and hydrogen peroxide to digest and decompose the sample, and then atomic absorption spectrometer or inductively coupled plasma emission spectrometer for quantitative analysis of metal content.

Cadmium and its compounds: Microwave digestion wet digestion, sulfuric acid and hydrogen peroxide were used to digest and decompose the samples, and then atomic absorption spectrometer or inductively coupled plasma emission spectrometer was used for quantitative analysis of metal content.

Mercury and its compounds: Samples were treated by microwave digestion or reflux in the presence of nitric acid and sulfuric acid, and then quantified metal content by atomic absorption spectrometer or inductively coupled plasma emission spectrometer.

Hexavalent chromium compounds: samples were treated by dissolution method, and hexavalent chromium content was quantitatively analyzed with UV-Vis spectrophotometer.

Analysis of harmful organic substances

RoHS/WEEE Directive prohibits: Polybrominated biphenyls (PBBs), bromophenyl ethers (PBDEs)

Chemical Standard/Test Reference Test Instruments

PBBs and PBDEs 76/769/EEC, 83/264/EEC Gas Chromatography - Mass Spectrometry

Complex and important sample preparation

At present, the cable extraction method (EPA8081) and ultrasonic extraction method are often used to extract polybrominated biphenyls and polybrominated diphenyl ethers into the container, because the body and complex additives and additives in the plastic product will also be dissolved into the extractant, so it is also necessary to clean the sample to be measured and separate from the complex matrix.

Precision Quantitative Analysis - Organic Item Detection

The EU RoHS Directive requires that after July 2006, 7, electronic and electrical products placed on the EU market must not contain six harmful substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. The accurate detection of PBBs and PBDEs is carried out by gas chromatography-

Mass spectrometry continuous instrument detection method.

Depu Instruments will fully assist you to provide you with the most cost-effective products and perfect solutions to help you easily cope with the EU RoHS directive.

Wide mass range: 10-1000u

The molecular ion peak of decabromodiphenyl ether can be detected, so that the quasi-definitive and quantitative analysis of polybrominated biphenyls and polybrominated diphenyl ethers can be performed in one instrument and in one injection analysis. The measured data are completely consistent with the theoretical calculation results, and the gas chromatography-mass spectrometer is displayed

There is still stable and correct analysis ability in high-quality segments, so as to ensure accurate analysis results. The patented design of the GC-MS instrument provides the highest sensitivity and ultra-stability

Due to the complexity of the actual sample (plastic) matrix, it is inevitable that the pretreated extract will contain a large number of other co-dissolved interferences, which will bring a high background and drown the low content of the target compound. Cause missed detection. Gas chromatography-mass spectrometry is extremely sensitive

degree and selectivity. This greatly simplifies complex pre-processing and helps you obtain stable test results quickly and accurately.

RoHS laboratory establishment program

The establishment of ROHS laboratory can not only meet the detection of banned substances in the electronics industry, but also meet the detection of restricted substances in the POHS directive

ROHS analytical instrument configuration:

1. X fluorescence spectrometer

2. Inductively coupled plasma emission spectrometer

3. Gas chromatography-mass spectrometer

4. UV-visible spectrophotometer

The test sample can be quickly scanned first, such as using XRF instruments to conduct rough testing of the sample, and when the control elements are found to exceed the control standard or are close to the control standard, and then further confirm by chemical methods, this combination of physical and chemical detection can greatly reduce the detection success

Cost, shorten the testing cycle, virtually improve the detection efficiency, for the production unit, is profitable.

1. Rapid analysis instrument: XRF series can be elemental scanning and film thickness detection

Function: Detect which elements are contained in the sample and the range in a short time.

At present, our company can detect three types of ROHS:

EDX2800 EDX3000D EDX3600B Vacuuming measures light elements

2. Chemical precision testing instruments:

At present, the detection instruments for heavy metals in electronic products or toys are mainly detected by ICP, GC/MS detection by brominated flame retardants, and UV detection by hexavalent chromium, which are required by IEC62321 and SJT11365 standards.
