Full textLaser ablation coupled to a mass spectrometer with inductively coupled plasma (LA-ICP-MS) is a promising direct solid sampling technique. Due to the lack of matrix matched standard materials laser ablation is not well established in polymer analysis. In a recent study a polymer dependent interaction with the laser beam was reported, which resulted in a polymer depending ablation rate. The usage of the carbon-13-signal intensity as internal standard to correct these differences as commonly applied has been critically discussed in literature. In this work as part of a BMBF-supported MaxLaP-project (matrix effects during laser ablation of polymers) matrix matched standards based on polyethylene and acrylonitrile butadiene styrene were developed. In these materials Br, Cd, Cu, Cr, Fe and Sb were incorporated as organic and inorganic compounds through extrusion. Quantitative composition of the materials was determined by ETV-ICP-OES, DC-arc-OES, XRF and ICP-MS after high pressure microwave digestion. Analytical methods were optimized for trace analysis in plastic matrices. Microscopic homogeneity was examined by µ-SyXRF as well as LA-ICP-MS. In order to investigate the matrix effects and to determine the possibility of a matrix independent calibration for plastic materials, the influence of the chemical form of the additives, size of the formed particles and the type of the plastic on the LA-ICP-MS measurements were analyzed. The correction of the material uptake by the carbon-13-signal was successfully applied for 21 different types of plastic. However, different incorporated additives show a different transport and ionization behavior. Furthermore, our results confirm a different enrichment of the additives depending on particle size and a significantly different particle formation for different types of plastic, which leads to a more pronounced elemental fractionation by not using a matrix matched calibration.

Full textBesides the safety of food the focus on food packaging material increases in public. The migration of substances from the packaging into food is undesired and regulated by law. To ensure consumer protection legal limits and requirements have to be kept. The migration of regulated und not regulated substances has to be verified which means an analytical challenge. The determination of nitrogen containing substances (NCS) from food can coatings by screening of migrating, non-volatile substances with a molecular mass below 1000 Da from the coatings was carried out. The applicability of a nitrogen selective detector for the screening of coating extracts which contain nitrogen containing susbtances was shown. For the investigations crosslinking substances, liquid lacquers as well as migrates of the finished coatings have been available for determination. Nitrogen containing and potential migrating substances have been identified first in the raw marterial of the coating in order to quantify them in the migrates of the coating. It should be shown if substances from the raw materials or reaction products migrate into the food simulant. In order to show the relevance of the migrating nitrogen containing substances in respect to other non nitrogen containing compounds the overall migration of the available coatings was determined. It could be shown that the amount of NCS in the overall migrating substances was between 0.2 and 6.3 %. Focus of the second part of the work was on food packing made of plastic. First an HPLC-method with ELS detection for the determination of the overall migration in sunflower oil was developed. Purpose of this determination was to predict the influence of temperature, time and thickness of the layer on the migration behavior with fatty food of sealing layers in high temperature range (> 70 °C) by means of design of experiments. A statistical software computed a regression equation for the calculation the overall migration based on a Box-Behnken-Design. The highest influence could be shown for the temperature. The modell showed a duplication of the determined overall migration with 10 °C increase of temperature. The determination of plastic additives out of the 95 % ethanol and isooctane migrates of packaging material should also be conducted. An HPLC-screening method for the determination of 25 additives in the fat substitutes was established. The identification of the migrating additives was carried out with UV detection (DAD), FLD, ELSD and CLND. By means of the different detection systems it was possible to cover the structural diversity of the mainly used additives. To insure the results MS detection was used. By means of this investigations a clarification of the total migrating substances of a multilayer film was 50 % (95 % ethanol) and 10 % (isooctane), respectively. The concentration of the migrating substances on the scale of things is nearly identical. The difference in the overall migration (95 % ethanol: 1.2 mg/dm2, isooctane: 5.6 mg/dm2) can not be clarified by migration of additives. As other migrating substances ethylen oligomers can be identified. The quantification was carried out for the first time with 1HNMR spectroscopy. An almost complete identification of migration substances of the overall migrate in food simulants can be shown. The migrating ethylen oligomers have been further investitgated. With the help of different chromatographic and spectroscopic methods a further characterisation of the migrating ethylen oligomers was successul
