Title: A SYSTEM AND A METHOD FOR COMPOSITIONAL ANALYSIS
Abstract:
A system (100) for producing analysis data indicative of presence of one or more predetermined components in a sample (110) is presented. The system comprises source equipment (120) for directing a particle stream (130) towards the sample (110), detector equipment (140) for measuring a distribution of particles scattered from the sample (110) as a function of a scattering angle (θ), and processing equipment (170) for producing the analysis data based on the measured distribution of the scattered particles and on reference information indicative of an effect of the one or more predetermined components on the distribution of the scattered particles. The scattering angle related to each scattered particle is an angle between an arrival direction of the particle stream and a trajectory (160) of the scattered particle. The system utilizes different directional properties of scattering related to different isotopes, different chemical substances, and different isomers.
