Helium in the Williston Basin?

The Williston Basin is known for its oil and gas reserves. But helium? “We know that there’s helium there in the Basin,” said state geologist Ed Murphy. “That’s from what little records we have on that.” Murphy said the Canadians have much more information on this. “They’ve got economic quantities of helium, produced in the 1960s and 1970s,” Murphy said. “They’re back in now with a big drilling program.” Murphy said that program is centered on southern Saskatchewan. “And we’re saying, ‘Let’s take a look at North Dakota,'” Murphy said. The Survey has put out a report, to guide industry, if it was to come to North Dakota. “We said, ‘Here’s the area that looks the most promising,'” Murphy said. Murphy said helium was reported to be in short supply, because of Middle East embargoes. He said the helium market is very volatile — but it could be an opportunity for some companies.

Influence Of Low-vacuum Helium Cold Plasma Pre-treatment On The Rooting And Root Growth Of Zoysiagrass (Zoysia Willd.) Stolon Cuttings

The influence of low-vacuum helium cold plasma treatment on the rooting percentage, root growth and physiochemical properties of zoysiagrass stolon cuttings was studied. Zoysiagrass stolon cuttings were pre-treated with 0, 100, 200, 300 and 400 watts (W) of cold plasma for 15 seconds. The cold plasma positively stimulated rooting and improved the root growth of the zoysiagrass stolon cuttings, and the 300 W treatment produced the best effect. The rooting percentage and root growth parameters, including the root length, total root surface area, total root volume, average root diameter, and root dry weight, significantly improved in response to the cold plasma treatment. In addition, the water uptake and relative conductivity of the stolon cuttings increased significantly in response to the cold plasma treatment. The results revealed that cold plasma-stimulated rooting and root growth appear to be a consequence of the improvement in permeability and water absorbing capacity of zoysiagrass stolon cuttings. The results of the present study will provide inspiration and support for the application of cold plasma in the vegetative propagation of plants.

Helium Depth Profile Measurements Within Tungsten Coatings By Using Glow Discharge Optical Emission Spectrometry (GDOES)

In the present paper results concerning the implementation of the Glow Discharge Optical Emission Spectrometry (GDOES) for measure the He depth profile within W coatings are given. The He emission line situated at 587.5 nm was used in this respect. W coating containing He up 10 at.% and with thickness of 5 μm have been obtained by Combined Magnetron Sputtering and Ion Implantation (CMSII) method. The coatings structure and morphology was investigated using Scanning Electron Microscopy (SEM) measurements. The He retention within the coatings was evaluated by using Thermal Desorption Spectroscopy (TDS). Time-of-Flight Elastic Recoil Detection Analysis (TOF ERDA) measurements has been used to determine chemical composition of the coatings. Results of TOF-ERDA measurements results were used to calibrate the GDOES equipment. Using these data the GDOES depth profiles of the He within W coatings have been obtained.

Testing Diffusion of Cosmic Rays In The Heliosphere With The Proton-to-helium Ratio Data From AMS

After six years of continuous observations in space, the Alpha Magnetic Spectrometer experiment has released new data on the temporal evolution of the proton and helium fluxes in cosmic rays. These data revealed that the ratio between proton and helium fluxes at the same value of rigidity \R=p/Z (momentum/charge ratio) is not constant at \R≲,3,GV. In particular, the ratio is found to decrease steadily during the descending phase of Solar Cycle 24 toward the next minimum. We show that such a behavior is a remarkable signature of the
β×λ(\R) dependence in the diffusion of cosmic rays in heliosphere, where β is their adimensional speed and λ(\R) is their mean free path, a function of rigidity for all nuclei. This dependence is responsible for distinctive charge/mass dependent effects in the time-dependent modulation of low-rigidity particles.

Addressing the Helium Shortage…Again

Many times I feel like the same problems are presented to me again and again; Problems that were solved years ago. It must have something to do with getting older. Noooo! Please, let me elaborate and start this blog post off in a more positive manner: familiar problems rise to the surface from time to time and it is, in fact, very nice to have the solution at hand. One reoccurring issue is helium supply in the laboratory. We are all aware that helium is a carrier gas for many applications in GC and GC-MS. To put it bluntly: no helium means no analysis, which is practically a nightmare for all laboratories. This year we are, again, facing a helium shortage and have already seen letters from providers with a warning that their supply might be delayed. According to the industry, it may become a continuous problem considering helium is one of the elements considered to be in danger of complete depletion. In fact, helium is mined as a byproduct of uranium and cannot be produced or manufactured. There are only three major sources of helium in the world, and in the past the industry experienced a problematic supply from time to time. In 2012, there was a global helium shortage that was flagged across the laboratory world. Since then, a new possible source was discovered and it was back to business-as-usual. It is convenient to play the blame game in such matters. We ask the question, “Who is using all this precious helium?” The normal consumer only knows helium as a gas used for inflating balloons. One might wonder if there has been a craze for children’s balloons recently. The answer is a bit more complicated: Helium is used for diagnostic purposes and is an important element to perform MRI . I am sure we all can agree that medical images are a key aspect for public health and until there is a good alternative for helium use in advanced medical imagery, we will have to continue using helium in MRI scanning. So, we need to look to our own industry for helium alternatives as a carrier gases. One alternative is switching to hydrogen as a carrier gas. The main benefit is that hydrogen allows for fast chromatography and you can potentially speed up your analysis. One of the other great things about hydrogen is that it can be produced in the lab. The downside, however, is that hydrogen is quite explosive and extra measures need to be taken to prevent accidents from happening in the laboratory. But these matters can be solved by modern electronics. So why are we not seeing hydrogen being used in the lab all the time? The answer: method transfer. Most of the existing methodology is based on helium use. Switching to hydrogen would require all the methods to be re-optimized and re- validated. Additionally, when you are using a mass spectrometer, sensitivity drops due to the fact that hydrogen is, simply put, a smaller molecule and is more difficult to pump away in the vacuum of the MS.

Another alternative is using the Thermo Scientific Helium Saver.

Here’s how it works: the carrier gas in the separating column is still helium, but the gas that is needed for flushing the injector is nitrogen. The result? No need for method transfer, no loss of sensitivity for the MS, and a huge helium savings. The principle is as simple as it is elegant and the savings on gas is tremendous. For most applications the carrier gas flow is 1-2 ml/min and the split flow is 25-50 ml/min, leading to a helium consumption of at least 26ml/min. With the helium saver, the consumption is only the carrier gas flow so it uses 25 times less as in most standard applications.
