Shim-on-Chip Design for Microfluidic NMR Detectors
No full textIn this contribution
we present a novel system for shimming capillary
samples such as used in microfluidic NMR probe heads. Due to the small
sample size, shimming microliter samples using regular shim coils
is complicated. Here we demonstrate the use of a series of parallel
wires placed perpendicular to B0 as a
Shim-on-Chip shim system. This is achieved by placing a ribbon flat
cable horizontally over the NMR detector, in our case a stripline.
The current through each wire of the ribbon cable can be controlled
independently employing a 16 channel DAC. This makes for a simple,
cheap, and easy to construct alternative to regular shim systems.
The Shim-on-Chip is, nevertheless, quite flexible in creating a magnetic
field which matches the inhomogeneity of the magnet in one dimension.
The capillary sample geometry is well suited for this type of shimming
since its length is much larger than its width. With this Shim-on-Chip
system we have reached line widths of 2.2 Hz (at 50%) and 27 Hz (at
0.55%) on a 144 MHz NMR spectrometer without any other room temperature
shims. Unlike regular shims, the Shim-on-Chip is located inside the
NMR probe. It is always centered on the NMR sample, because of this
the shims have an intuitive effect on the line shape. Therefore, the
manual shimming is simpler when compared to a regular shim system,
as it is difficult to position a microliter sample in the exact center
of the shim coils. We furthermore demonstrate the use of a Shim-on-Chip
method in a 400 MHz Rapid-Melt DNP system. Decent line widths were
achieved even for a sample which is located off-center inside the
NMR magnet
Letter from Moses F. Shim to James B. Finley
No full textRev. Shim, a member of the Iowa M.E. Conference, writes on behalf of one Jacob Bennett, son of Joseph Bennett. Jacob needs to prove that he was not an inmate at the Ohio Penitentiary from 1827 to 1836. Shim would like Finley to research this name. If found, Shim would like information from Finley about the prisoner\u27s size, complexion, etc., in order to prove that the Jacob Bennett in Iowa is not the person who was incarcerated in Ohio.
