Abstract

An NMR system comprises an NMR probe comprising multiple NMR detection sites. Each of the multiple NMR detection sites comprises a sample holding void and an associated NMR microcoil. The NMR system further comprises a controllable fluid router operative to direct fluid sample to the multiple NMR detection sites.

Claims

exact text as granted — not AI-modified
1 . An NMR system comprising, in combination: 
 an NMR probe comprising multiple NMR detection sites each comprising a sample holding void, and an associated NMR microcoil; and    a controllable fluid router operative to direct fluid sample to the multiple NMR detection sites.    
     
     
         2 . The NMR system of  claim 1  wherein the multiple NMR sites are integrated in a probe module.  
     
     
         3 . The NMR system of  claim 2  wherein the sample holding void of each of the NMR detection sites is in a capillary-scale fluid channel in the module.  
     
     
         4 . The NMR system of  claim 2  wherein the sample holding void of each of the NMR detection sites is in a micro-scale fluid channel in the module.  
     
     
         5 . The NMR system of  claim 1  wherein the controllable fluid router is operative in response to an electrical input signal.  
     
     
         6 . The NMR system of  claim 1  wherein the controllable fluid router is operative to direct fluid sample to any selected ones of the NMR detection sites.  
     
     
         7 . The NMR system of  claim 1  wherein the controllable fluid router is operative to direct fluid sample to any selected ones of the NMR detection sites corresponding to the input signal.  
     
     
         8 . The NMR system of  claim 7  further comprising an operative component in communication with the router and operative to generate the input signal to the router.  
     
     
         9 . The NMR system of  claim 8  wherein the multiple NMR sites and the operative component are integrated in a probe module.  
     
     
         10 . The NMR system of  claim 7  further comprising a controller unit in communication with the router and operative to generate the input signal to the router.  
     
     
         11 . The NMR system of  claim 10  wherein the multiple NMR sites and the controller unit are integrated in a probe module.  
     
     
         12 . The NMR system of  claim 5  further comprising a controller unit operative to receive information from any of the multiple NMR detection sites and to generate the input signal to the router based at least in part on said information.  
     
     
         13 . The NMR system of  claim 5  further comprising an operative component and a controller unit operative to receive information from the operative component and to generate the input signal to the router based at least in part on said information.  
     
     
         14 . The NMR system of  claim 13  wherein the operative component, the controller unit and the multiple NMR sites are integrated in a probe module.  
     
     
         15 . The NMR system of  claim 1  wherein one or more of the multiple NMR detection sites are in communication with a data processing unit.  
     
     
         16 . The NMR system of  claim 15  wherein the data processing unit is integrated in a probe module.  
     
     
         17 . The NMR probe module of  claim 15  wherein the data processing unit provides an input signal to the controllable router.  
     
     
         18 . An NMR probe module comprising: 
 multiple NMR detection sites each comprising a sample holding void and an associated NMR microcoil; and    a controllable fluid router operative to direct fluid sample to the multiple NMR detection sites.    
     
     
         19 . An NMR smart probe comprising: 
 multiple NMR detection sites each comprising a sample holding void and an associated NMR microcoil;    a controllable fluid router operative in response to an electrical input signal to direct fluid sample to the multiple NMR detection sites; and    a controller unit in communication with the router and operative to generate the input signal to the router.    
     
     
         20 - 55 . (Cancelled)
