Phthalic Hazardous Substances Detection in Plastic

发布日期:2016/7/4 8:37:55  点击次数:479

   Phthalate ester plasticizer is a kind of modified material which is widely used in food packaging, toys, children products, PVC building materials, medical equipment as well as clothing and other items.

    Recently the European Union and the United States passed a series of phthalate esters on the instruction (1999/0238/COD). As the phthalate ester plasticizers and plastics and rubber matrix without the formation of bonding with each other to maintain their own independent chemical properties, therefore it will be dissolved when coming into contact with water, oil. Phthalates has a reproductive toxicity, also has mutagenic and carcinogenic effects.

    Therefore, this series of instruction provided, at present for the plastic products, rubber, textiles, toys, children supplies, etc. which containing DEHP, DBP, BBP, DINP, DIDP and DNOP, the content of these six kinds of phthalate plasticizer shall not exceed specified levels. Or else it can not be exported to the United States and Europe.

    Currently the usual detection technology is GC-MS, but the GC-MS detection technology reserves a long time and poor separation, peak shape is also less than satisfactory. Besides the GC-MS is expensive, which makes manufacturing enterprises to take a larger financial burden.

    Jiangsu Skyray Instrument Co., Ltd, make a large number of technical studies against this instructions and make the appropriate improvements on the current company products and provide domestic enterprises the solutions for detecting these six kinds of hazardous substances, which can also be extended to other harmful substances. From the experimental results, our company has provided solutions with characteristic of better separation, chromatographic baseline stability, peak shape rules of good-looking, simple handling peaks, no interference and simultaneous testing other harmful substances with high precision and accuracy.

    Skyray will launch a special analysis package of phthalate ester plasticizer for different samples to develop a different method of sample handling, hardware includes: pre-processing equipment, testing instruments, etc.; software includes: sample preparation treatment methods, sample analysis, customer training and after-sales service, etc. It takes about five working days for the entire adjustment and training.
