20110006198 | ATMOSPHERIC PRESSURE ION SOURCE PERFORMANCE ENHANCEMENT - Electrospray ionization sources interfaced to mass spectrometers have become widely used tools in analytical applications Processes occurring in Electrospray (ES) ionization generally include the addition or removal of a charged species such as II+ or other cation to effect ionization of a sample species. Electrospray includes ionization processes that occur in the liquid and gas phase and in both phases ionization processes require a source or sink for such charged species. Electrolyte species, that aid in oxidation or reduction reactions occurring in Electrospray ionization, are added to sample solutions in many analytical applications to increase the ES ion signal amplitude detected by a mass spectrometer (MS). Electrolyte species that may be required to enhance an upstream sample preparation or separation process may be less compatible with the downstream ES processes and cause reduction in MS signal. A new set of Electrolytes has been found that increases positive and negative polarity analyte ion signal measured in ESMS analysis when compared with analyte ESMS signal achieved using more conventional electrolytes. The new electrolyte species increase ES MS signal when added directly to a sample solution or when added to a second solution flow in an Electrospray membrane probe. The new electrolytes can also be added to a reagent ion source configured in a combination Atmospheric pressure ion source to improve ionization efficiency. | 01-13-2011 |
