Underwater mass spectrometry systems can be used for direct in situ detection of volatile organic compounds and dissolved gases in oceans, lakes, rivers and waste-water streams. In this work we describe the design and operation of (1) a linear quadrupole mass filter and (2) a quadrupole ion trap mass spectrometer interfaced, in each case, with a membrane(More)
Quantitative Feedback Theory (QFT) is employed to achieve time domain specifications on the tip position of a hybrid actuated single-link flexible manipulator. The manipulator payload conditions are varied to assess the robustness of the synthesised control system to parametric uncertainty. A combination of QFT multi input multi output (MIMO) design methods(More)
