The analysis was performed on a Trace 1300 gas chromatograph coupled to a TSQ 8000 Evo triple quadrupole mass spectrometer and a TriPlus 300 autosampler (Thermo Fisher, Austin, TX, USA). The Li anode of the Li–O2 cell with 50 mM TESI after 60 cycles was prepared in the argon-filled glove box. The Li anode was put into a 20 ml glass sample container. The container was transferred from the glove box to the GC-MS analysis system and heated at 90 °C for 20 min to vaporize DES. 1000 μl of headspace was immediately sampled using a gas syringe and injected in the ion-trap GC-MS, equipped with capillary column (TG-5, 30 m × 0.25 mm × 0.25 μm) using helium as gas carrier. The temperature program for the GC run was: 25 °C initial column temperature, 10 °C min−1 to 120 °C, held for 5 minutes. High purity helium gas was used as the carrier gas and the pressure was kept constant at 75 kPa.

For GC/MS–MS analysis 1 µl of the samples was injected with a splitless liner in a Trace 1310 Gas Chromatograph (Thermo Fisher Scientific Inc., Waltham, MA, USA) and analytes were separated on a TG-5SILMS GC column (15 m × 0.25 mm × 0.25 μm) (Thermo Fisher Scientific Inc., Waltham, MA, USA). Helium as carrier gas was used with a carrier flow rate of 1.5 ml/min and a split flow rate of 20 ml/min. The oven temperature program was as follows: 1 min at 120 °C, heating to 220 °C with a heating rate of 30 °C/min, heating to 300 °C with a heating rate of 50 °C/min up to 300 °C, 300 °C held for 0.5 min. The retention times for TNT, 4-ADNT, 2-ADNT and 2,4-DA-6-NT were 3.50 min, 4.32 min, 4.50 min and 4.64 min, respectively. Eluted analytes were ionized with electron ionization (EI) or negative chemical ionization (CI) with methane as the reagent gas and analyzed with a TSQ 8000 EVO Triple Quadrupole Mass Spectrometer (Thermo Fisher Scientific Inc., Waltham, MA, USA) in MRM-mode.

The chemical tissue analysis was performed as described in Strehse et al. (2017 (link)): Mussel tissues were thawed, whole meat was placed in a 50 mL polypropylene tube per mussel, and homogenized using a T25 Ultra-Turrax (Ika Works Inc., Staufen im Breisgau, Germany). Tissues were aliquoted into 1.0 g portions in 50 mL polypropylene tubes, and 5 mL gradient grade acetonitrile (Th. Geyer GmbH & Co. kg, Renningen, Germany) were added per tube. Each sample was mixed for one minute using a VF2 vortex mixer (Ika Works Inc., Staufen im Breisgau, Germany). Tubes were centrifuged for 5 min at 4 100 rpm (20 °C) with a Heraeus Megafuge 11R centrifuge (Thermo Fisher Scientific Inc., Waltham, MA, USA). Supernatants were decanted and filled with acetonitrile to a total volume of 10.0 mL. GC/MS-MS analysis was performed on a TSQ 8000 EVO Triple Quadrupole Mass Spectrometer (Thermo Fisher Scientific Inc., Waltham, MA, USA) with a Trace 1310 Gas Chromatograph (Thermo Fisher Scientific Inc., Waltham, MA, USA) and using a TraceGOLD™ TG-5SilMS GC column (30 m × 0.25 mm × 0.25 µm).

The instrument analysis was performed on a GC-MS/MS system (Thermo Fisher Scientific, U.S.A) comprised of a Trace 1300 gas chromatography, a TSQ 8000 EVO triple quadrupole mass spectrometer, and a Triplus RSH autosampler. The gas chromatography was equipped with a Supelco Equity-1 capillary column (30 m x 0.25 mm i.d. x 1.00 µm film thickness, Sigma-Aldrich, Missouri, U.S.A). Samples were injected in PTV splitless mode with the following parameters: 1.5 mL/min constant helium flow rate, 1 µL injection, 0.5 min splitless time, backflush features on at 7.5 min. The PTV temperature program was: starting at 70 °C, stayed for 0.02 min then increased to 280 °C at 8.5 °C/s, maintained for 7.5 min then increased to 330 °C at 10 °C/s, held constant until the end of the analysis. The analytes were separated using the following oven program: starting at 60 °C for 1 min; increased to 120 °C at 30 °C/min; increased to 250 °C at 8 °C/min; then increased 30 °C/min to 260 °C, held for 3 min. The transfer line was kept constant at 300 °C. The ion source was operated at 280 °C and 70 eV.
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.
