Plasticizer storm hit many companies to launch testing programs

Foreword: Recently, the melamine "plasticizer" was raided by the food industry, causing a major food safety crisis in Taiwan. Everyone heard "plastic" discoloration. There are 206 companies involved in this storm, and 522 products may be contaminated. Almost all major food companies in Taiwan have been involved.

The impact of “plasticizers” has now exceeded that of Taiwan Island. Since countries and regions that import Taiwan products have not included “plasticizers” in the scope of monitoring of food additives, this incident has also caused relevant countries and The area was shocked.

Plasticizer DEHP refers to "2-ethylhexyl phthalate". It is a toxic plastic softener for chemical industry. It is a colorless and odorless liquid. Therefore, it can increase ductility, elasticity and softness, and is often used as a raw material for sofas, car seats, rubber tubes, cosmetics and toys, and is an industrial additive.

In response to Taiwan's "plasticizing agent" incident, analysts and test instrument manufacturers have taken actions one after another and released the corresponding analysis and testing solutions at the first time.

Thermo Fisher Releases Food Plasticizer Testing Program

“Plasticizers” such as DEHP and DINP are similar to artificial hormones. Long-term accumulation of high doses in the body may cause children to be sexually distorted, including small genitalia and insignificant sexual characteristics. Although it is currently impossible to prove whether it is carcinogenic to humans, animals can cause cancer. reaction. Plasticizers must not be added to foods according to law. This article mainly provides several common "plasticizers" detection methods.

Bona Ejer provides methods for the detection of phthalates in foods
For the detection of phthalate esters in beverages, extraction with liquid-liquid extraction using organic solvents can easily cause instability of the test results of different samples. Bona Eyre can provide a solid-phase extraction method to solve this problem, using the CleanertPEP glass solid phase extraction column for the solid phase extraction enrichment of phthalates in beverages, which can then be used with liquid chromatography or GC/ MS detection.

LabTech Launches Total Plasticizer Solution

Common gel purification systems on the market, many valve bodies and pipelines have a large number of plastic or rubber parts, and these parts are added to various degrees of various plasticizer components, resulting in the plasticizer sample processing process Contamination in the medium causes a high background, the detection limit of the impact analysis, and the reliability of the data. Labtech has launched a special gel purification system for sample processing of plasticizers. The system piping adopts a stainless steel design, which eliminates the problem of contamination introduced during sample purification and greatly increases the sensitivity and reliability of analysis.

The Application of Dai'an's Three-component Liquid Chromatography in the Detection of "Plasticizer"
Dai An Company uses a unique dual-triple liquid chromatography system to enrich 15 mL samples online using an IonPac® NG1Guard (10 μm, 4.0 mm×35 mm) enrichment column. The enriched samples can be directly switched to the analysis system. Remove the complex time-consuming manual or semi-automatic sample preparation process, and separate it on an Acclaim® 120C18 (5μm, 4.6mm×150mm) analytical column at 40°C, in a concentration range of 0.5μg/L to 50μg/L, four Phthalates have good linearity, linear correlation coefficient R> 0.9991, detection limit (by S/N=3) DMP 0.1μg/L, DEP 0.25μg/L, DBP 0.10μg/L, DEHP 0.25 μg/L.
