Phthalic acid ester plasticizer two is a kind of widely used a modified food packaging materials, toys and children's products, PVC building materials, medical equipment and other items of clothing.
Recently, the European Union and the United States through a series of adjacent benzene two formic acid ester instruction (1999/0238/COD). Because of the adjacent benzene two formic acid ester plasticizer and plastic and rubber matrix did not form a bond, each other to keep the chemical properties independently. So in the exposure to water, oil, will be dissolved. Phthalic acid esters with two reproductive toxicity, but also has the mutagenic and carcinogenic effect.
So this is a series of instructions, currently contains DEHP in plastics, rubber, textiles, toys, children's products, DBP, BBP, DINP, DIDP and DNOP, these 6 kinds of phthalate two formate plasticizer content shall not exceed its content of plastic parts required. The content may be exported to Europe and the United states.
The current testing technology is widely used by GC-MS, but GC-MS high purchase cost to users at the same time prohibitive, GC-MS detection of the effect is not good, and the retention time is long, the separation degree is not very good, the shape is also unsatisfactory, and related maintenance funds is relatively high, the user cost will be overwhelmed.
Shanghai Wufeng Scientific Instrument Co., a large number of research technology according to the instructions, the corresponding improvement of the current company's products, provides the detection of 6 kinds of harmful substances to the domestic export enterprises, and can be extended to the solution of other harmful substances test. Even after the detection of the type of the material increases, the user does not need to put a very high cost, you can upgrade to the new directive. From the experimental results, the solution provided by our company has better separation, chromatographic baseline stability, shape rules good-looking, peak peak before and after simple treatment, no interference, and other harmful substances for coexistence can be detected, did not interfere with each other, with high precision and accuracy. Please look at the following map:
Figure (1) is a plasticizer standard solution: 6 kinds of standard solution plasticizer, After analyzing the following standard sample spectra (Figure 1);
?
Figure (2) samples provided by a toy export enterprises, with our solutions are the following chart:
See from the above map, our solutions provide a convenient method for the domestic export enterprises, help enterprises start to check these harmful substances from the procurement of raw materials, thus ensuring from production to export finished products can fully meet the requirements of relevant international order.
