NMR is a non destructive technique and so reducing acquisition time can be used either to increase sample throughput, or to lower the detection limit. To lower the detection limit a given amount of time is used to acquire a greater number of scans than would normally be acquired. A relatively recent method for reducing acquisition time is ASAP (Acceleration by Sharing Adjacent Polarization)1. The ASAP technique speeds acquisition by greatly reducing the length of the relaxation delay.
