Dinonyl adipate (DNA) n. A non-alcohol ester used as a plasticizer for cellulosic, acrylic, styrene, and vinyl polymers. 

Standards in use for quantitation are essentially employed in three ways. With the internal standard technique, known quantities of a carefully selected (usually high purity) substance, the internal standard, are added to both samples and standards. The internal standard (preferably a non-commercial product) should have similar chemical and physical properties to the analyte, in particular, volatility and functional groups, in order to react in the same way to changes in the chemical environment (e.g. dinonyl adipate may serve as an internal standard for the determination of di(2-ethylhexyl) adipate). Solutions of pure additives used as standards may be unsatisfactory due to the difference in the evaporation profile between pure additives and those blended in the polymer samples. For example, a pure Permanax WSP sample evaporates in the ion source from about 30 to 150°C, whereas Permanax WSP blended in PE evaporates from about 120 C (m.p. of PE) to 350°C [17]. If one opts for polymer-based calibration standards the homogeneity of the samples is of crucial importance. Using internal standards in quantitative analysis is advantageous, for instance, in cases where the sample thickness cannot be determined exactly, or in gaseous samples with unknown total pressure.
