1. Product Overview

RoHS is the European Union's legislation restricting the use of hazardous substances in electrical and electronic equipment (EEE). Its full name is the "Restriction of Hazardous Substances Directive." This directive primarily regulates the material and process standards of electrical and electronic products, making them more beneficial to human health and the environment. Initially, the directive established limits for the use of six substances in electrical and electronic products: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. On June 4, 2015, the Official Journal of the European Union (OJ) published the revised RoHS 2.0 Directive (EU) 2015/863, officially adding DEHP, BBP, DBP, and DIBP to the list of restricted substances. Following the publication of this revised directive, EU member states were required to transpose and implement it in their respective national regulations by December 31, 2016. Furthermore, starting July 22, 2019, all electrical and electronic products (except medical and monitoring equipment) exported to the EU will be required to comply with these restrictions. Starting July 22, 2021, medical devices (including in vitro medical devices) and monitoring equipment (including industrial monitoring equipment) will also be subject to these restrictions.

Testing for the four phthalate esters in electrical and electronic products requires pulverizing, extracting, cleaning, and contaminating the electronic samples before testing with the appropriate instruments. This initial sample preparation is time-consuming. In March 2017, the Py/TD-GC-MS method was officially approved by the International Electrotechnical Commission (IEC) (a national standard has also been established, pending approval). This method is used to analyze phthalates restricted by the RoHS Directive (IEC 62321-8:2017) for the regulation of electrical and electronic products. As a low-profile alternative to Py/TD-GC-MS, Py/TD-GC has been extensively tested and shown to generally meet the RoHS 2.0 phthalate screening requirements.

Compared to traditional Soxhlet extraction, the Py/TD-GC coupled system allows for rapid screening of phthalates in electrical and electronic products. This method requires no pretreatment and eliminates the need for organic solvents. Results can be obtained directly from weighed samples, making it simpler and faster.

5. Analysis

5.1 Analysis Process

(I) Sample Preparation

Weigh the sample to a total mass of 0.5-1.0 mg. Weigh the sample boat and return the balance to zero. Use a carving knife to cut approximately 0.5 mg of sample and place it in the sample cup. Then, place the sample tube in the heating device.

(II) Reference Conditions

1) Sample Split Injection: Solid sample weight should be between 0.5 mg and 1 mg, liquid sample weight should be approximately 1 μl

2) FID detector temperature: 300°C, injection port temperature: 300°C

3) Temperature program: 100°C (hold for 1 minute), then increase at 20°C/min to 300°C (hold for 14 minutes)
