Used GENESIS MegaSIMS #293669186 for sale

GENESIS MegaSIMS is a surface analysis instrument that utilizes Secondary Ion Mass Spectroscopy (SIMS) to measure the elemental composition of a sample surface. With high sensitivity and speed, MegaSIMS is able to identify elements present at levels down to parts per million. It features a novel LASSEN ion optics that allows for increased resolution and a higher degree of surface elemental composition analysis. The LASSEN ion optics has several useful attributes. It allows for the use of very low secondary ion energies that are ideal for SIMS analysis of biologically relevant molecules. This means that atoms of surface-bound molecules can be mass analyzed with fewer chemical biases that allow for a clearer understanding of the sample's chemistry and composition. Additionally, by using GENESIS MegaSIMS with secondary ions of low energies, the ion intermediate energy is reduced, which reduces sample charging. This in turn reduces the need for specialized sample preparation before conducting the analysis. MegaSIMS is equipped with several mass spectrometers in order to optimize the analysis. The primary detector used is a secondary electron detector which is used to detect incoming secondary ions. The secondary ions are then analyzed by a matrix-assisted laser desorption (MALDI) system to identify the elemental composition of the surface. This includes the identification of the possible location of the elements. The MALDI system is also useful in measuring isotope ratios in order to further analyze the sample. Once the MALDI analysis is complete, a Secondary Ion Mass Analysis (SIMA) takes place which measures the relative abundance of elements present in the sample. This is a useful tool for abundance mapping and can detect elements with a wide range of concentrations. GENESIS MegaSIMS can also be used for isotope analysis. This type of analysis is often used in radiometric dating, or to understand the origins of a sample. For isotope analysis, a noble gas mass spectrometer is also available. This is used to identify the different isotopes of a particular element since the differing masses of these isotopes can be used to identify different wealth of a sample. Overall, MegaSIMS is a powerful, reliable, and versatile tool that can be used for the comprehensive analysis of sample surfaces. The effective use of its LASSEN ion optics, as well as its other mass spectrometers, allows for the comprehensive analysis of the elemental composition of a sample, as well as isotope ratios and relative abundance mapping. This makes it a useful tool for any laboratory looking to analyze either solid or liquid samples.
