On June 4, 2015, the Official Journal of the European Union (OJ) issued the RoHS 2.0 revised directive (EU) 2015\/863. Based on the original 6 substances restricted by RoHS (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. NOTE: The RoHS 6 substances can be tested by LISUN EDX-2A RoHS Testing Equipment<\/a>), four phthalates were added to the list of restricted substances under RoHS 2.0, and it has been compulsorily implemented since July 22, 2019. LISUN has developed the EDX-4 RoHS 2.0 testing system, which is based on the solution for rapid screening of phthalates through pyrolysis desorption. It is specifically designed for the testing of the following four hazardous substances:<\/p>\n\n\n\n\n\n\n\n

Bis(2-ethylhexyl) Phthalate (DEHP)<\/td>\n117-81-7<\/td>\nIt is mainly used as a plasticizer for PVC. PVC is used as an insulator in electrical and electronic equipment, such as cables and wires. A small amount of DEHP is used for other non-polymer applications, such as the electrolyte of ceramics or capacitors in electronic products.<\/td>\n<\/tr>\n
Butyl benzyl Phthalate (BBP)<\/td>\n85-68-7<\/td>\nIt is mainly used in combination with other plasticizers in PVC components such as cables, sockets, pipes, and shock absorbers. In addition, it is also used in some non-polymers such as paints and glues.<\/td>\n<\/tr>\n
Dibutyl Phthalate (DBP)<\/td>\n84-74-2<\/td>\nIt is mainly used as a plasticizer in PVC flooring. In electrical and electronic equipment, it may be present in synthetic leather, textile coatings, PVC materials, printing inks, sealants, and glues.<\/td>\n<\/tr>\n
Diisobutyl Phthalate (DIBP)<\/td>\n84-69-5<\/td>\nIt is used as a plasticizer for PVC, and can be used as a substitute for DBP. It can also be used as a plasticizer for cellulose resins, vinyl resins, nitrile butadiene rubber, and chloroprene rubber.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Part 1: Product Features<\/strong><\/p>\n

\u2022\u00a0No chemical pretreatment required: There is no need for ultrasonic extraction or extraction with chemical reagents. Samples can be directly injected in solid or liquid form, and the operation is simple. Short sample testing time: The sample testing time of 20 minutes per sample fully meets the rapid detection needs of corporate users.
\n\u2022\u00a0No environmental impact assessment required, and no professional laboratory needed: Without the need for reagents or pretreatment, no waste gas or liquid is generated, so there is no need to apply for an environmental impact assessment.
\n\u2022\u00a0100% sample applicability: Chemical methods are only suitable for soluble polymer samples (applicable to 70% of samples), while this method is applicable to soluble, hardly soluble, and insoluble polymer samples (applicable to 100% of samples).
\n\u2022\u00a0No professional laboratory environment required: It only requires an ordinary operating space equipped with an air conditioner, power supply, operating table, nitrogen, and a refrigerator to be installed and used.<\/p>\n

B.\u00a0 Specification of the Gas Chromatograph:<\/strong>
\n\u2022\u00a0The split\/splitless injection system makes the analysis flexible and convenient.
\n\u2022\u00a0It comes with a two-way valve control system, which facilitates online automatic injection.
\n\u2022\u00a0The high-precision gas control system makes the gas flow clear at a glance, allowing for more accurate setting of the gas flow rate.
\n\u2022\u00a0The comprehensive detection and fault diagnosis system enables you to quickly identify and solve problems occurring in the instrument.
\n\u2022\u00a0A wider temperature control range: ambient temperature + 5\u00b0C to 400\u00b0C, expanding the range of sample analysis.
\n\u2022\u00a0The unique gas cut-off protection system can, to the greatest extent, prevent the detector and the chromatographic column from being damaged.
\n\u2022\u00a0The column oven can be equipped with an ultra-low temperature control system. The ultra-low temperature control down to -80\u00b0C can meet your needs for analyzing substances with low boiling points.
\n\u2022\u00a0The inter-column compensation circuit provides electronic compensation for the baseline drift during the programmed temperature rise operation, reducing the complexity brought about by the second column, detector, and auxiliary flow system. Two single-column compensation channels can be installed simultaneously.<\/p>\n

\n\u2022\u00a0Users can recalibrate the oven temperature and freely set the maximum temperature. The intelligent rear \u2013 door opening system has a steplessly variable air intake and exhaust volume, which shortens the system stabilization time after heating or cooling. The time taken for the column oven to cool from 300\u00b0C to 50\u00b0C is less than 12 minutes.<\/p>\n

D. Specification of the Flame Ionization Detector (FID):<\/strong>
