Segments of the root, 2 to 2.5 mm in length, were taken at 2 cm from the tip of the root using a scalpel blade, taking care not to squash the root. 01/06/2010В В· Working with such samples requires significant care to avoid losing the sample, both at the sample preparation stage and at the NanoSIMS analysis stage. For the electron-transparent foil in particular, careful control of the NanoSIMS primary Cs + beam is required to achieve optimal ion imaging before holes begin to form in the section.

NanoSIMS 50/50L uses a magnet to separate the masses. According to the law of electromagnetism, namely the Lorenz magnetic force, the trajectory of a charged particle traveling in a magnetic field is curved, with the curvature proportional to the ratio between the particle's mass and charge (m/q). The NanoSIMS 50L uses a rastered ion beam to scan across the sample surface. Secondary ions are sputtered from the sample and extracted to a double-focusing magnetic-sector mass spectrometer. Multiple detectors allow the parallel mapping of up to seven ion species, simultaneously.
