    Determination of Selected ASTM Perfluorinated Compounds (PFCs) Using LC-MS/MS

    ASTM methods D7968-14 and D7979-15 are used to determine the same list of PFCs but in different matrices. ASTM method D7968-14 lists soil as a matrix while ASTM method 7979-15 lists water, sludge, influent, effluent and waste water as matrix options. These methods use different extraction techniques but both evaluate the samples by liquid chromatography/tandem mass spectrometry (LC/MS/MS). We ...

    Compression Test Apparatus Set

    In many land use systems all over the world soil deformation is a major problem due to increasing land use intensity. On arable soils machine traffic is continuously intensified with respect to load and wheeling frequency leading to (sub-)soil compaction and deeper soil degradation concerning hydrologic or pneumatic functions. Altered soil functions, in particular reduced hydraulic conductivities ...
