Waveform Generator Boards The optional Wave Form Generator III board replaces the Generator II board and is functionally identical to the 10 bit amplitude old board and can also utilize a 12-bit amplitude format. The Wave Form Generator III board creates an infinite number of waveform experiments. The generator's output drives the transmitter board, adjusting the signal amplitude and phase. Waveform Generator boards are required for imaging experiments. - Varian Waveform Generator Kit Installation Pub. No. 01-999137-00, Rev.A0599 Z-gradients The pulsed field gradient coil and shims can cause gradients throughout the sample. Shimming gradients affect the homogeneity of the magnetic field while pulsed field gradients are used in experiments for coherence selection, spin crushing and spatial encoding. -Daina Avizonas, TAC Gradient Shimming - A quick tour of problems and solutions 5/10/2002 Triple Resonance Probe The Triple Resonance Probe is specifically designed for demanding applications in biomedical NMR such as 2D, 3D, and 4D triple resonance experiments on isotopically enriched proteins. -Varian Triple-Resonance NMR Probes Pub. No. 01-999125-00, Rev.A0699 VXR Broadband Probe The VXR broadband probe is a multinuclear probe optimized for superior broadband performance for lower frequency nuclei. -Varian Broadband NMR Probes Pub. No. 01-999122-00, Rev.A0300 Triple Resonance Microflow Probe The 1H{13C/15N} 60µL PFG Triple Resonance microflow probe combines pulsed field gradients (PFG) and triple-resonance capabilities with microflow capabilities. Microflow probes allow liquid sample transfer from LC-NMR and VAST systems. Micro flow probes contain a flow cell that is connected to inlet and outlet connectors on the probe base. Analytes can be injected into the probe with an HPLC pump, the VAST autosampler, or manually with a syringe. -Varian Microflow NMR Probes Pub. No. 01-999127-00, Rev.A0299 VAST Accessory The VAST accessory uses the automation capability of the INOVA NMR spectrometer and VNMR software to take a sample from a vial or well on the Liquid Handler and move it into the Microflow probe. When the sample is in place, NMR data can be acquired. When the NMR experiment is finished, the sample is removed and either discarded into a waste container or returned to the source container. After removing the sample, the liquid path is washed to minimize cross-contamination or carryover between samples. -Varian VAST Sample Management System Installation Pub. No. 01-999144-00, Rev.B0601
