GB-Lowestoft: for High resolution mass spectrometric analytical screens of cigarette butts, sediment and seawater

There is a requirement for an analytical service for high resolution mass spectrometric (HRMS) screens to include: a) A series of quick tests with direct probe time of flight-mass spectrometry of coarse homogenates of cigarette butts (both freshly smoked and weathered) as a simple screen with a view to identify substances present at detectable concentrations. A list of substances of particular interest is provided at the end of this section for tenderers to consider. b) Suspect screening by liquid chromatography-HR...
