Snippet: For LC-MS/MS, an Aria Transcend TLX-II system and TSQ Vantage were utilised (both ThermoFisher Scientific, San Jose, USA). Isocratic chromatography with a 5:95 (V/V) mixture of (A) 0.1 per cent (V/V) aqueous formic acid and (B) 0.1 per cent (V/V) formic acid in methanol was performed using an Acentis fusedcore C18 analytical column (150×4.6 mm, particle size 2.7 µm, Sigma-Aldrich). Flow rate was 0.8 ml/minute with the column being maintained at.....

Isocratic chromatography with a 5:95 (V/V) mixture of (A) 0.1 per cent (V/V) aqueous formic acid and (B) 0.1 per cent (V/V) formic acid in methanol was performed using an Acentis fusedcore C18 analytical column (150×4.6 mm, particle size 2.7 µm, Sigma-Aldrich). Flow rate was 0.8 ml/minute with the column being maintained at 40°C using a HotPocket (ThermoFisher Scientific). LC-MS/MS was carried out in selected reaction monitoring mode (two m/z transitions) using positive atmospheric-pressure chemical ionisation.
