Application Note: Claristep Filtration Assembly: A Novel Sample Preparation Method Suitable for the Analytics of Phthalates in Solid Environmental Samples
The filtration clean-up of particle laden environmental samples for phthalates analytics is a common step in sample preparation prior to GC-MS. Here, we demonstrate that Claristep® syringeless filtration units 0.45 μm and 0.2 μm are suitable for the filtration clean-up of phthalate samples. A mix of eight phthalates and one adipate was filtered at a concentration of 10 μg/mL with neither detectable adsorption nor releasing of these compounds from the filter unit. Furthermore, it was shown by GC-MS screening that no detectable compounds were extracted.
