Also, mass spectrometry (MS) was used for the identification of MOSH and MOAH components. In general a simple test which is easy to carry out on-site is needed to comply with safety regulations in packaging products. \r\nWe found out that when used a glass column with a 10 mm inner diameter and filled with activated silver silica gel (containing 0.3 % AgNO3) as a sorbent bed for the SPE process, the MOSH fraction was eluted with 13 mL of n-hexane. The MOAH fraction was eluted with 15 mL of solvent mixture of 70 % dichloromethane (DCM), 25 % n-hexane. 5 % toluene and gravitational elution to control the elution speed provided the best results. \r\nIn this study, it was suggested that the amount of solvent used during the SPE process will gain intensive attention since the handling and evaporation of it is time consuming.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jovin Greye (greye) on 2016-06-10 13:50:14.644710.
