The oceanographic instrumentation program supports requests to acquire instrumentation for the collection, processing and analysis of oceanographic data. This proposal from Woods Hole Oceanographic Institution requests funding for acquisition of a hybrid QQ quadrupole tail that will convert an existing High Resolution Mass Spectrometer into a state-of-the-art Magnetic Sector Mass Spectrometer (MS-MS). The entire facility will be available for shared-use by the oceanographic research community and will support the research efforts of many NSF-funded scientists. The quadrupole extension adds the capability of obtaining structural elucidation of high molecular weight macromolecules. The PIs are particularly interested in analyzing high-molecular- weight, marine organic materials, such as the products of chlorophyll decomposition and structural variations of kerogens and polysaccarides.
