The ESA is two parallel, curved plates held at a particular electronic potential.Ions of different energy will therefore travel different paths.The secondary ion mass spectrometry is a technique of analysis in microscale of sample surface.
SHRIMP is used for many diverse purposes: to date minerals by U-Th-Pb dating; analyse stable isotopes (eg carbon, sulphur and oxygen) in biogenic and inorganic materials; to look at isotope anomalies in meteorites and lunar soil.
These are SHRIMP II (it came after SHRIMP I, which has recently been decommissioned), SHRIMP RG (reverse geometry) and SHRIMP SI, which is dedicated to analysing light stable isotopes.
The high mass resolution of SHRIMP IIe is achieved by the use of double-focussing mass spectrometer (simultaneous energy and mass refocussing) with a very large turning radius of Magnet and Electrostatic Analyser.
SHRIMP has many applications: zircon dating in copper-uranium-gold-silver deposits, uranium-lead dating of sulphur in the sulphide minerals that form metal ores, the isotopic composition of sulphur in the giant base metal ore bodies.
The oldest zircon on Earth was measured in the SHRIMP Facility.
Research on prograde and retrograde metamorphic reactions, P-T-t loops, fault movement and deep crustal fluid circulation all rely heavily on the Curtin SHRIMP facility, and it’s extensive collection of accessory mineral Reference Materials.How charged particles move in electromagnetic field is depend on the mass-to-charge ratio of the particles.By utilizing its properties, it is allowed to fly the charged particles in the field to determine the mass number from its orbit.The SHRIMP is the abbreviation of Sensitive High-Resolution Ion Microprobe.SHRIMP is an analytical instrument that the Australian National University (ANU) has begun to develop since 1973, and secondary ion mass spectrometry to analyze the secondary ions generated by irradiating a primary ion beam on the sample surface.Therefore, it is possible to analyze sample as a solid without chemical treatment, such as sample dissolution and column separation.
