Conditions for the simultaneous determination of quaternary ammonium herbicides by liquid chromatography–electrospray–mass spectrometry were established. Two electrospray sources with different configurations and two mass analyzers were used: a Turbo Ionspray™ source with a triple quadrupole instrument and a Z-spray source with a time-of-flight (TOF) analyzer. The separation was performed using ion...
We describe an estimation of measurement uncertainty calculated by the ''bottom-up'' approach for the determination of the oestrogenic compound nonylphenol in treated water samples by solid-phase extraction (SPE) and solid-phase microextraction (SPME) procedures and GC/MS detection. The results were compared and the different contributions to the uncertainty were evaluated. A study of the linear range...
