“…PLE was carried out on a Dionex ASE-350 accelerated solvent extraction system (Sunnyvale, CA, USA) in 10-ml stainless steel cells according to the procedure developed by Celeiro et al [21] and successfully used in our earlier work for the analysis of pulp and paper products [33]. The weighed portion (0.5-1.0 g) of the averaged sample was placed in the cell and extracted with methanol at 110 • C and 100 bar for two 5-min cycles.…”

“…Thus, the purpose of this study was to close this gap and to develop a rapid and sensitive SFC-MS/MS method for the simultaneous determination of the 10 most important from the practical point of view PAEs in paper and cardboard materials. As a sample preparation technique, we chose PLE, characterized by high throughput and recov-ery rates, which we have successfully used earlier in the analysis of pulp and paper products [33]. High purity (>99.99%) carbon dioxide (NIIKM, Moscow, Russia) and HPLC gradient grade methanol (J. T. Baker, Phillipsburg, NJ, USA), were used as a component of the mobile phase and extractant (methanol).…”

Phthalic acid esters are widely used as components of industrial and consumer products including paper and cardboard packaging materials in contact with food or human skin. Being endocrine-disrupting chemicals, phthalic acid esters have a negative effect on human health and must be controlled in pulp and paper products. In the present study, supercritical fluid chromatography-tandem mass spectrometry in combination with pressurized liquid extraction was proposed for phthalic acid esters determination in such objects. Octadecyl stationary phase with non-endcapped silanol groups ensured rapid (4 min) separation of the 10 priority phthalic acid esters in isocratic elution mode and allowed for effective elimination of interferences from the trace impurities of phthalic acid esters in the mobile phase. The attained limits of quantitation are in the range of 0.7-10 μg/L in extracts and 0.02-0.3 μg/g in paper and cardboard samples.The developed method is distinguished by analysis rapidity, easy sample preparation procedure, high selectivity, low susceptibility to mobile phase contamination with analytes, low cost, and environmental friendliness due to the use of carbon dioxide as a main component of the mobile phase. The method was successfully tested on real samples of toilet paper and food packaging paper and cardboard in which eight analytes were found at the levels of 0.03-43.5 μg/g.
