High-performance liquid chromatographic determination of unreacted monomers and other residues contained in dental composites.
HPLC method was developed for determination of bisphenol A diglycidyl methacrylate (bis-GMA), bisphenol A diglycidyl acrylate (bis-GA), bisphenol A dimethacrylate (bis-DMA), glycidylmethacrylate (GMA) and triethylenglycol dimethacrylate (TEGDMA). Separation was carried out on a reversed phase Omnisphere 5 C18 column with a gradient mobile phase of CH3CN/H2O. UV detection was set at 205 nm and 275 nm parallel. The limits of quantification were found. The method has been applied for quantification of unreacted monomers trapped in polymer network of fillings.
