Increasing Spatial Resolution of Lipid Biomarker Analysis by LDI FTICR-MS

The combination of temperature proxy potential of lipids in the sedimentological record with the high spatial resolution of laser desorption ionization (LDI) coupled to FT-ICR-MS can be used to produce estimates on sub-decadal to sub-annual scales and potentially provide crucial, previously hidden insights on the conditions of past climates and aid marine micro-organism knowledge. This scientific poster describes the use of a 12T solariX FTICR-MS coupled to a dual ion source with the Smartbeam II Laser for LDI FTICR-MS analysis of several cm-long sediment core segments.
