KJ-PYGC60 Toluene Detector

Introduction to the RoHS Directive

TEU RoHS 1.0 (effective June 1, 2006) restricts six hazardous substances including lead, mercury and cadmium. RoHS 2.0 (effective July 22, 2019) adds four phthalate substances: Butyl Benzyl Phthalate (BBP), Dibutyl Phthalate (DBP), Di(2-Ethylhexyl) Phthalate (DEHP) and Diisobutyl Phthalate (DIBP). The limit value of all restricted substances is ≤1000ppm (cadmium ≤100ppm).This instrument enables rapid screening of the four newly added phthalates, and can be expanded to detect Polybrominated Biphenyls (PBBs) and Polybrominated Diphenyl Ethers (PBDEs). It is also compatible with the detection of Chlorinated Paraffins (CPs) and Tetrabromobisphenol A (TBBPA) required by RoHS 3.0.

Application Scenarios

It is widely applied in industries such as electronics, electrical appliances, toys, clothing, leather, food, wire materials, hardware, plastics, ink, chemicals, and medicine. It can quickly screen for phthalate ester substances, and also supports the expansion of detection for multiple types of harmful substances. It is suitable for all scenarios including factory quality inspection, incoming material control, finished product sampling, third-party testing, and scientific research experiments.

Product Features

● Quick screening test, simple and easy to operate. Start it with one click, no complex training required for professionals. It can be used immediately.

● The thermal cracking release instrument adopts a 5-stage program temperature control, with high temperature control accuracy. Combined with a rapid heat dissipation system, the preparation time of the instrument is short, improving the detection efficiency.

● The sample injection process has no cold spots or dead volume, effectively ensuring the repeatability and accuracy of the test results, and the data is more reliable.

● No need for chemical reagent pretreatment. Solid, liquid and gas samples can be directly injected for detection, eliminating cumbersome procedures and reducing operating costs.

● Compatible with various sample substrates, with strong compatibility, meeting the detection needs of different industries and different forms of samples.

● Equipped with professional control software, with an intuitive interface, it can quickly set various parameters, and the operation is convenient and efficient.

● The temperature and gas path control of gas chromatography are precise, further ensuring the stability and repeatability of the detection data.

● No use of hazardous chemical reagents, no hazardous waste liquid discharge, no need for environmental impact assessment, environmentally friendly, meeting the low-carbon operation requirements of enterprises.

● Low requirements for the operating environment, an ordinary air-conditioned room can meet the installation and use requirements, no special site renovation is needed.

● After the detection is completed, an automatic detection report is generated, supporting custom report headers and tails, and adapting to different enterprise report specifications.

Standard Testing Protocol

According to the IEC 62321-8-2017 standard, the samples do not require complex pre-treatment. Just take 1-1.9mg of the sample and fix it onto the quartz tube. For liquid samples, directly drip them onto the quartz cotton and place it in the thermal decomposition device. The test can be conducted with just one click. The instrument is preset with optimized test conditions. Once the test is completed, a report will be automatically generated. The minimum detection limit is approximately 50 ppm, the linear correlation coefficient is greater than 0.999, and the RSD is ≤ 5%. This fully meets the requirements for rapid screening of phthalates in RoHS 2.0.
