Gel Permeation Chromatography, GX‐271 GPC Clean‐Up System, automated sample

方案摘要：

Gel permeation chromatography (GPC) is a highly effective method for the removal of high molecular weight interferences such as lipids from a fatty food prior to analysis for the compounds of interest. GPC has been used to clean up fatty foods contaminated with plasticizers and other plastics additives.

方案详情：

Plastics are ubiquitous in our society and are extensively used in a large variety of
packaged foods. A variety of chemicals that enhance the physical quality of plastics
are often added as well. Some commonly used additives include plasticizers (such
as phthalates) to improve flexibility, UV filters for protection from sunlight,
brightening agents, coloring agents, and preservatives. Enhanced by a number of
environmental factors, some of these additives may migrate into food products that
have been packaged using plastics. There is currently a great deal of interest in
measuring the migration of these compounds into food products, as considerable
uncertainty exists regarding the human health risks associated with exposure to
such compounds.

Gel permeation chromatography (GPC) is a highly effective method for the removal
of high molecular weight interferences such as lipids from a fatty food prior to
analysis for the compounds of interest. GPC has been used to clean up fatty foods
contaminated with plasticizers and other plastics additives.

This note describes the use of GPC clean‐up
to separate a variety of plastics additives,
such as phthalates, Chimassorb® 81 (a UV
absorber and stabilizer), Irganox® 1076 (an
optical brightener) and Uvitex® OB (an
antioxidant and thermal stabilizer) from a
representative edible oil sample prior to
analysis.

The samples were characterized by various techniques: UV/vis spectroscopy, dynamic light scattering, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, nuclear magnetic resonance and zeta potential. The NPs were metallic and surface oxidated, exhibiting absorption peak at 257 nm due to the surface plasmon resonance. The interaction between the NPs and various amino acids was studied and revealed a selective sensibility to cysteine on a range of concentration from 80 to 720 μM, which we attribute to a dimerization of cysteine to cystine probably complexed to the nanoparticle surface by electrostatic interactions, leading to the modification of the NP absorption spectrum. 关键词：Bismuth; Nanoparticles; Laser ablation; Cysteine
