Summary on Grant Application Form
A new generation of ICP-MS has entered the market to meet the need for an instrument which is able to measure and process multi-element data for short transient signals. A recently launched commercially available inductively-coupled plasma mass spectrometer (ICP-MS) could revolutionise data collection in inorganic mass spectrometry. This instrument employs a time of flight mass spectrometer (TOF-MS) as a mass filter, still with an ICP as an ion source, instead of using a quadrupole or double focussing sector field. This opens up a large variety of possible sample introduction systems, which could not be used with the former ICP-MS. The fast data collection is suitable for short transient signals, produced by the introduction of small amounts of sample into the plasma. The time-of-flight mass spectrometer (TOF-MS) guarantees that signals of less than a second can be analysed for more than 250 mass to charge ratios. More than 27,500 individual mass spectra can be recorded within a second. This ICP-TOF-MS will be used for the following sample introduction systems:* Determination of volatile metal(loid) species using capillary gas chromatography or flash-GC.* Determination of metallo-proteins using capillary electrophoresis.* For the determination of micro inclusions or spatial distribution of trace elements in cement, rocks or bones a laser ablation facility can be coupled to the ICP-TOF-MS for quantitative measurements and more precise isotope ratios.* A micro sampler device enables the introduction of micro-volumes (<10(L). This will be used for cytoplasm, rock inclusions, pore waters, et cetera.* Electrothermal vaporisation could be used to vaporise liquids or solids directly into the plasma.
