Morphological structure was observed by scanning electron microscopy (SEM) (SUPPATM 55, Zeiss, Germany). Fourier transform infrared spectroscopy (FT-IR) spectrum was recorded on an FT-IR spectrometer (Nicolet 710 IR, California, USA). X-ray diffraction (XRD) data was conducted on a Siemens D500 diffractometer (Karlsruhe, Germany). The Magnetic hysteresis loops were studied on a PPMS 9 vibrating sample magnetometer (VSM) (Quantum Design, USA). The GC–MS/MS analysis was carried out on a Thermo Scientific TRACE 1310 gas chromatograph equipped with a Thermo Scientific TSQ 9000 triple quadrupole mass spectrometer with an electron ionization (EI) source, and a TriPlus RSH auto sampler and a split/splitless injector (Thermo Fisher Scientific,Waltham, USA). The operation, data aquisition and data analysis were performed on Chromeleon Software Version 7.2.8. The GC–MS/MS parameters are detailed in Supplementary Material . The molecular structure, GC retention times, optimized mass spectrum parameters and log P of seven PAEs are showed in Table S1 .

The equipment and settings for the gas chromatograph and tandem mass spectrometer were previously described elsewhere for the analysis of UV 328 and its metabolites in both human blood and urine (Denghel and Göen 2020 (link), 2021 (link)). A TRACE 1310 gas chromatograph, a TriPlus RSH autosampler and a TSQ 9000 triple quadrupole mass spectrometer with an AEI source installed (Thermo Fisher Scientific, Waltham, USA) were used for GC–MS/MS analysis. A volume of 1 μL sample was injected into the system in splitless mode. A 5%-phenyl-arylene/95%-dimethyl polysiloxane low-bleed capillary column (HP5 ms UI, 60 m × 250 μm × 0.25 μm) (Agilent Technologies, Santa Clara, USA) was used for gas chromatographic separation. Chromeleon Software Version 7.2.8 was used for device control and data analysis.

A TRACE 1310 gas-chromatographic system equipped with a TriPlus RSH autosampler and a split/splitless injector was used for the analysis of the urine, blood, and plasma samples. The gas-chromatographic system was coupled to a TSQ 9000 triple–quadrupole mass spectrometer equipped with an advanced electron ionization (AEI) source (Thermo Fisher Scientific Inc., Waltham, USA). Chromatographic separation was performed on a (5% phenyl)-methylpolysiloxane low-bleed capillary column (HP-5msUI, 60 m × 250 µm × 0.25 µm, Agilent Technologies, Inc., Santa Clara, USA) at a constant flow rate of 1 ml/min using helium as a carrier gas. Total analysis time was 44 min. The GC–MS/MS equipment and parameter-specific settings were used as described in earlier publications for the analysis of urine (Fischer and Göen 2021 (link)) and blood samples (Fischer and Göen 2022 (link)). Plasma samples were analyzed using the same parameter-specific settings as for the analysis of blood samples.

VPs were quantitated exactly as previously described using GC–MS/MS [7 (link),10 (link),20 (link)]. In brief, a Trace 130 gas chromatograph equipped with a TSQ9000 triple quadrupole mass spectrometer (GC–MS/MS; both from Thermo Fisher Scientific; Waltham, MA, USA) was used to acquire all date in selected reaction monitoring mode. The GC column used was a Zebron ZB-5MSplus (30 m × 0.25 mm × 0.25 μm; Phenomenex; Torrence, CA, USA) and helium was used as the carrier gas (1.5 mL/min). A split ratio of 1:4 was used and 1 μL was selected as the injection volume. The GC oven and MS system parameters including all transitions were exactly as previously used [7 (link),10 (link),21 (link)]; see Figure S1 Supplemental for representative extracted ion chromatograms for all analytes.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
