ABSTRACT:
An automated sample changer, controlled by gas fluidic circuitry, integrated with a Nuclear Magnetic Resonance (NMR) spectrometer provides a means for sequentially transferring samples to and from such spectrometer without an attendant to control such transfer. Such a changer comprises a means for holding a series of samples, a robot arm cooperating with such holding means and disposed in alignment with the sample receiving tube of an NMR spectrometer, a gas fluidic circuit to sense the required action, and a second gas fluidic circuit integrated therewith to provide the energy to make the transfer.
