US Classification:

324309, 324321

Abstract:

Devices and related methods for nuclear magnetic resonance (NMR) analysis of particulate materials are provided including a detector chamber configured for insertion into an NMR spectrometer and configured to receive particulate materials in a fluid. A circulation chamber is attached to and in fluid communication with a first end of the detector chamber. A transition region is between the detector chamber and the circulation chamber, and a fluid supply interface is at a second end of the detector chamber that is configured to attach to a fluid source. The detector chamber, the circulation chamber and the transition region are sized and configured such that, when fluid flows from the fluid supply interface into the second end of the detector region, a circulating current is formed in the transition region and/or the circulation chamber such that the particulate matter is contained in the circulation chamber by the circulating current.
