The EDX-4 RoHS 2.0 test equipment meets the requirements of IEC62321-8. The four kinds of o-benzene controlled by Rohs2.0 are plasticizers and are hardly volatile materials. They need high temperature (200℃-450℃) to evaporate.

The current IEC standard is PY/TD-GC-MS (thermal cracking/ Thermal desorption-gas chromatography-mass spectrometry detector), where the thermal cracking temperature is high, up to 1200 degrees, many large molecular substances are cracked into small molecular substances, which will Interference and false positives to the results, so need to use MS mass spectrometers to qualify. And this equipment we use EDX-4 micro-cracking desorption technology (thermal cracking/thermal desorption-gas chromatography), we only need to quantify the corresponding o-benzenes, so our heating range is set in the range of 200°C-450°C, so that all four o-benzenes are volatilized and enter GC (gas chromatograph) for quantification without affecting the results of other macromolecular substances.

Therefore, EDX-4 test equipment meets the requirements of IEC62321-8 and is more reasonable and scientific to set a more accurate temperature range, and GC quantification is more suitable than GCMS.

Analysis condition:
• Micro-pyrolysis program temperature rise 200 ° C -450 ° C
• Microthermal cracking time 2 min
• Injection method: split injection
• Liquid injection volume: 1 ul
• Solid injection volume: 5mg or less
• Inlet temperature: 250 °C
• FID detector temperature: 300 °C
• Temperature programmed to 50 °C (for 1 min), to 20 °C per minute to 450 °C (for 4 min)
• The method does not require pre-treatment, the consumable is 2.5cm long quartz tube, quartz cotton, pretreatment column, the solid sample is placed in the middle part of the quartz tube, the two ends are fixed with quartz cotton, and then the prepared sample tube is placed in the heating chamber Just fine.
