In this work, an automated high-throughput sample preparation method using thin film solid phase microextraction (SPME) for the analysis of multiple prohibited substances in plasma is proposed. A biocompatible SPME extraction phase made of hydrophilic–lipophilic balance particles immobilized with ...

A number of vapor detection methods have been proposed. These vapor detection methods have found use in laboratory analysis. Among them are electron capture detection, gas chromatography detection, mass spectrometry detection, plasma chromatography detection, bio-sensor detection and laser photoacoustic dete...
Each plasma donation can amount to as much as 800 mL compared with 470 mL for whole blood; the increased volume may contribute to the faster reduction in serum PFAS levels found in the plasma donation group. In addition, plasma donation may be more efficient at reducing the body’s burden ...

It was also found that these novel proteinic associated substances, although substantially equal to the active factor in their primary activity, are less than 1/50 in the leukocytosistic activity, less than 1/10 in the histamine sensitivity increasing activity, less than 1/25 in antigenicity and...
Studies on humans have shown that these chemicals cross the placental barrier, are transferred to the fetal circulation and also found in maternal milk (Kuklenyik et al., 2004; Midasch et al., 2007). The half-life of PFOS and PFOA in human serum is estimated to be 3.4 years and 2.7 ...
