A: Procedure for creating a 500-nL to 2-μL detection sample cells with susceptibility-matched epoxy plugs. Flow of (a) epoxy-mixture along the outside wall of (b) fused silica transfer lines (1 cm long, 360 μm OD 70 μm ID) inside each end of (c) thin glass capillary (2 cm long, 1 mm or 1.43 mm OD) is controlled with the suction of the (d) air-filled syringes fixed at each end of the transfer lines. The center (e) of the cell holds the desired detection volume. B: Actual image of a small volume cell with dried epoxy-glue plug, and fused-silica transfer lines. C: Single resonance circuit used in each coil with tuning capacitors, Ct (0–9 pF and 2.2 pF), matching capacitors, Cm (0–9 pF and 3.6 pF) and a 2 cm long, 0.181 in. OD, 50 Ω semi-rigid coaxial cable used to connect the coil to the rest of the circuit.
