All samples were subjected to freeze-drying prior to derivatisation. 80 μl of methoxyamine hydrochloride in pyridine (20 mg/ml) was added to each sample and incubated at 30°C with shaking for 90 minutes. The samples were added with 160 μl of MSTFA and allowed to incubate at 37°C with shaking for 30 minutes. The samples were transferred to autosampler vials and allowed to acclimatise to room temperature for 2 hours prior to the GC-MS run.
