RoHS2.0 pyrolysis gas chromatograph PY-DP8060

1 PY-DP8060 Product Overview

RoHSIt is EU legislation restricting access to electronic and electrical equipment（EEE）The full name of the regulation on the use of toxic and harmful substances in China is the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electronic and Electrical Equipment"(Restriction of Hazardous Substances)This directive is mainly used to standardize the material and process standards of electronic and electrical products, making them more conducive to human health and environmental protection. Initially, the directive specified lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers in electronic and electrical products6The usage limit of the substance.2015year6moon4The European Union Gazette(OJ)ReleaseRoHS2.0Revision instruction(EU)2015/863, officially willDEHPTheBBPTheDBPTheDIBPListed in the restricted substance list.

To test electronic and electrical products4The content of phthalates in the electronic sample needs to be crushed, extracted, purified, concentrated, and finally detected using corresponding instruments. The pre-treatment of the sample in the early stage requires a long time.This method is used to analyze the regulation of electronic and electrical productsRoHScommand(IEC 62321 - 8:2017)Restricted phthalates.Py/TD-GCasPy/TD-GC-MSThe low configuration alternative solution has been extensively tested and can basically meet the requirementsRoHS 2.0Screening requirements for ortho benzene.

Compared to traditional Soxhlet extraction, usingPy/TD-GCThe combined system can quickly screen for phthalates in electronic and electrical products. This method does not require pre-treatment and eliminates organic solvents. The analysis results can be obtained by directly weighing the sample and analyzing it on the machine, which is simpler and faster.

5 Analysis and Testing

5.1 Analysis Process

（1） Sample processing

The total mass of the weighed sample is:0.5-1.0 mgFix the sample in the middle of the quartz tube with tweezers and secure both ends with quartz wool; Add the liquid sample directly onto the quartz wool. Then put the quartz tube into the heating device.

（2） Reference conditions

1. Cracking program temperature rise:100℃（72℃/min）280℃(2 min)

2. Transmission line temperature:300℃

3. Sample diversion injection:solidEntersampleThe weight needs to be within0.5mgto1mgBetween them, the liquid should be1 ul左右

4. FIDDetector temperature:300 ℃, injection port temperature:300 ℃

5. temperature-programmed 100 ℃ (maintain)1 Minute by minute20 ℃ rises to300 ℃ (maintain)14Minutes)

6 Work environment

1. Environmental Requirements

The operating temperature is15°C～35°C, using temperature18°C～28°C，1.5hThe internal temperature change is not greater than2°CDue to the large temperature difference in the environment, air conditioning should be installed.

The relative humidity must be within≤75%Can be equipped with a dehumidifier.

Operation and storage require a non condensing and non corrosive environment.

The maximum dust particle density is80mg/m3.

2. Electrical Requirements

Voltage range:220V±10VThe frequency is50Hz.

The power supply has a grounding wire; No strong electromagnetic interference.

If funds permit, it is recommended to install an uninterruptible power supply（UPS）Power requirements10KVAThe above.

3. Requirements for instrument installation test bench

Provide sufficient laboratory space for installationPYTheGCThePCDevices such as printers.

The experimental platform must have a flat surface and be stable enough to support the weight of the entire system, includingPYTheGCThePCEquipment such as printers, with a total weight of approximately120kg.

Leave no less than around the experimental platform0.5mPlease do not place it against the wall due to the wide operating and maintenance space.

Suggest installing exhaust equipment above the experimental platform.

Suggested size for instrument installation laboratory bench: length250cm×wide80cm×tall75cm.

4. Requirements for sample processing test bench

The sample processing experimental platform is mainly used to place electronic scales and perform sample processing.

The sample processing experimental platform should be stable and durable, and reduce the generation of vibration.

Electronic scales should not be placed near ventilation openings or fans, as strong airflow can affect the weighing results.

The sample processing experimental platform should also have sufficient space for sample processing.

Suggested size for sample processing experimental bench: length120cm×wide80cm×tall75cm.

If space is limited, two long instrument installation and sample processing test benches can also be used150cmThe experimental table.
