Agilent 356-LC RI Detector Speed and Simplicity for the Determination of Epoxy Resins
ثبت نشده
چکیده
Epoxy resins are used widely in industry because of their strong adhesive properties, chemical resistance, mechanical toughness and high electrical insulation. Consequently they are often found in adhesives, stabilizers, sealants, varnishes and paints. Epoxy resins consist of bridged diepoxide oligomers of increasing molecular weight and there are various types corresponding to different molecular weight (MW) distributions and oligomeric profiles. The physical properties of epoxy resins are determined by their MW distribution and so their composition needs to be closely monitored during production.

The Agilent 1290 Infi nity II LC was used to analyze additives such as sweeteners, preservatives, and caffeine in various food products, beverages, and consumer toothpaste. The developed method facilitates accurate and sensitive determination of nine additives using a diode array detector (DAD) and an evaporative light scattering detector (ELSD) placed in series. After the DAD, a valve was inst...
متن کاملDetermination of Residual Methylmethacrylate Monomerin Denture Base Resins by Gas Chromatography
Acrylic base resins are widely used in orthopedics and dental surgery. It is generally accepted that due to the incomplete conversion of methyl methacrylate (MMA) monomer to the polymer form during polymerization of the resin, some MMA monomers remain in the hardened material. MMA monomer has been reported to cause abnormalities or lesions in several organs of animals. Study of the literatures ...
