Abstract

The current disclosure describes an automated high-throughput small object sorting system for separating small object via oil and/or moisture content using novel nuclear magnetic resonance (NMR) systems and methods. The disclosed systems and methods for measuring the oil and/or moisture content of a single small object in a low-field time domain NMR instrument are superior in sample throughput and signal-to-noise ratio to conventional NMR systems and methods (free induction decay or spin echo) for single small object oil/moisture measurement.
