The Uses of NMR Spectrometers

Modern science calls for modern equipment to detect light waves, radiation, minerals, and a whole lot more. Meanwhile, benchtop NMR spectrometers and boron NMR devices can help geologists study rocks and their pores. This is a popular and effective analytical method today, with “NMR” standing for “nuclear magnetic resonance.” This technology is also useful in the field of medicine, such as MRI machines in hospitals. Boron NMR devices are a fine option for studying the presence of boron in rocks and minerals, and many of these boron NMR devices are small enough to fight right onto a desktop. What else is there to know about these remarkable devices?

All About NMR Machines

This whole field of science was launched in 1946, when Felix Bloch and Edward Mills Purcell demonstrated NMR technology for the first time, and in 1952, they shared the Nobel Prize for their accomplishment. During the 1950s, commercial spectrometers were built, and widely used to become a vital tool for research chemists. And ever since the 1960s, superconducting magnets have been essential components for these devices, replacing earlier conventional electromagnets. NMR spectrometers, such as boron NMR sensing devices, can range from 60 up to 100 MHz whenever they are using permanent or electromagnets, and this work is essential for the huge drug development industry. Chemists must use portable and desktop NMR devices to help make breakthroughs in chemistry, and boron NMR devices, among other NMR spectrum sensors, can help.

These spectrometers are also quite useful for studying rock core samples, but it should be noted that NMR spectroscopy does not actually replace other analysis methods; more often, they are used side by side. Mercury porosimetry should be performed on the rock samples, and multiple accurate readings can be taken with devices such as NMR spectrometers. When used together, these methods allow a geologist to accurately gauge and analyze the details of the rock’s pores and the fluids involved. No other methods can analyze and collect data on the behavior of liquids in side a rock like this, and the geologist using these devices will know how much fluid will flow through the rock. This is a vital reference for knowing how much oil will flow through the rock and how much will instead be contained by capillary pressure. Better yet, these devices require little training to use, and are accessible for anyone to use during rock studies.

During this process, the sample is placed in a magnetic field, and then and a brief pulse of radio frequency (RF) energy will excite it. This will generate NMR signals from the liquid, may it be oil or brine. That signal will soon fade away, and that relaxation time is known (or decay rate) is known as the T2. Right after the pulse is made, the signal’s amplitude demonstrates how much fluid is present, and the liquid’s environment is measured by the T2. Some liquids, such as heavy oils or partially bound water, might have similar T2 values, but scientists can tell them apart with their differing diffusion characteristics. So, it is important to collect both T2 and diffusion rate data.
