NMR Spectroscopy

Hi sakis1,

Thank you for posting your tips to learn about the NMR that you use on your pistol.
I read your all the websites that show images where you say "look at google images for NMR.
I found that all the images showed powerful magnets that are used to create a very strong magnetic field to put unknown samples into so the NMR can be measured.
What I read from the links you showed, the only way to obtain a strong enough magnetic field to detect NMR frequencies requires using a superconducting magnet to make a 12 Tesla or more field field to insert a sample into. Liquid nitrogen and liquid helium are required in order to cool the solenoid coils cold enough to create the superconducting electromagnet so it can reach a large current flow to create this enormous magnetic field.
Of course, the superconducting magnet wire is usually a copper clad niobium-titanium alloy, because ordinary copper wire does not work.
I can see from your google NMR images that a computer is used to make calculations from the MHz data taken from the sensors in the NMR cyrogenic chamber.
The final calculation can identify what element was present from the precession data.
See below for some images I found when I made the google NMR image search as you said.

I had no idea that you have found a way to miniaturize a superconducting solenoid to generate intense magnetic fields strong enough to perform NMR spectrometry.
This is quite a feat.
This magnetic field is only 200,000 times stronger than the earth's natural field, but it should be strong enough to give adequate results for NMR spectroscopy.
It seems even more amazing that you have been able to identify buried samples without placing them into the 12 Tesla superconducting field on your PD first.


What I am wondering are three questions:
1. How do you keep the liquid nitrogen and liquid helium cold long enough for treasure hunting so your superconducting coil can maintain the 12 Tesla field?
2. What power source do you use to drive your superconducting magnet?
3. How did you manage to get buried treasures to precess when they are not first placed inside the 12 Tesla magnet cavity on your PD?

Best wishes,
J_P

Hi humhum,
These are very interesting links that explain NMR and NMR measuring instruments.
In your first link, I see a lot of good information about hydrogen resonance in various organic compounds that can be found when using a superconducting magnet to create a 2.35 Tesla magnetic field.

Your second link shows a portable NMR sensor made by researchers from the Berkeley Laurence Laboratory, University of California, and the Institute for Technical Chemistry in Germany.
They found a way to arrange a large Neodymium-Iron-Boron rare earth magnet produce a 0.2 Tesla magnetic field that could detect NMR.
It is good they were able to produce a 0.2 Tesla field, or it wouldn't work, according to the researchers.
“The variations within the magnetic fields of previous portable NMR devices are usually orders of magnitude too large to detect chemical shifts,”

Your third link shows another portable NMR sensor used by scientists near the north pole.
Since they are only looking for structural details of ice, they are not using equipment to identify the hydrogen in the ice.
They are trying to make images more like an MRI image that show the brine pockets in the ice samples they placed inside the coil of their Tecmag-Aries NMR system.
This Tecmag Aries MNR sytem can make images using only a 0.03 Tesla magnetic field, when you are using their software to display it on a computer.
The decay times look roughly similar to what we see on a proton magnetometer for distilled water to precess.

Do you think any of these articles show equipment that you think sakis1 connected to his PD using the metal locator circuit above?

Hi humhum,
I am reading the book where your first image came from [E. Buxbaum,
Biophysical Chemistry of Proteins: An Introductionto Laboratory Methods,
DOI 10.1007/978-1-4419-7251-4 34,© Springer Science+Business Media, LLC 2011].
On page 306, they say this works in superconducting magnetic fields.
"...nuclei with j ≠ 0 have a magnetic moment uN and can orient themselves parallel or antiparallel to an external mag-netic field (with a strength B0 of several Tesla), similar to a compass needle in themagnetic field of the earth. External magnetic fields are generated in superconduc-tive coils (Nb-alloys), cooled by liquid helium. The sample, however, is insulated from the cryogenic fluid and usually kept at room temperature...
... With the magnetic field strength cur-rently available (several Tesla), this LARMOR-frequency is in the order of several100MHz (500MHz at 12T is typical for current instruments)".

The magnet image they show is not a super conducting magnet coil that is used in the NMR spectroscopy.
They show this simple horseshoe magnet only to show which direction the magnetic field is pointing.
But the magnetic field they require has a strength of several Teslas or more.
They are talking about 9-12 Tesla fields that are created with superconducting magnets to produce 100-500MHz NMR frequencies.

To give you an idea,
The magnets that are used for holding papers the side of a refrigerator usually have about 0.05 Tesla field strength.
But 1 Tesla minimum field for NMR.
1 Tesla is 20 million times stronger than the earth's field, and it will cause all ferrous things near to become stuck to the magnet so you will have a very hard time to remove them.
But 1 Tesla magnetic field is not good for high resolution identification of samples. It is usually used for MRI imaging.
You need stronger magnetic fields which are carefully controlled for homogeneity to perform NMR spectroscopy.
This makes me think sakis1 did not use the equipment in this article, because I do not think sakis1 has a magnetic field anywhere near even 1 Tesla on his locator.

Your second image shows a bar magnet and some coils and a sample.
Is this sample the treasure that sakis1 recovered?

hi j_p

Hi kahyal,
The question I am asking is about this image you posted:



My question is about the sample we see at the left side marked yλIKO.
I wonder if you think this sample is some treasure that sakis1 recovered.

It is hard for me to understand how sakis1 was able to detect this treasure from long distance when I see the treasure is secured in a position at the NMR sensor that he added to his PD.
I am wondering how he detected this treasure from a long distance if it was secured in a position at the NMR coil where NMR measurements can be made.
We can read from your links above that NMR cannot work unless the sample is placed at the location of the NMR coil where we find a very powerful magnetic field.
It appears to me that maybe he already found a treasure and put it on the PD.
Is this correct?

But I also have a second question:
Is this really an NMR sensor?
I see only a bar magnet which cannot develop a strong enough field to measure NMR frequencies, even when you put the sample next to it.
Does this bar magnet have other parts we don't see in the image to create a magnetic field of several Teslas strength?

NMR or MRI

Exactly this

[COLOR="rgb(65, 105, 225)"]does not change anything, as much for the NMR is the functionality in MRI[/COLOR]

look at google images for NMR

!!

Maybe Sakis1 say this theory :

Hi humhum,
I do not think this is the theory that sakis1 says his PD can locate long distance with.
What this image shows is how to solve a sparking problem when you make MRI images to study how cell phone batteries perform.
It has nothing to do with remote locating.



The image you posted is from Argonne National Laboratory, which shows how they solved the problem of sparking that can destroy the NMR coil and the sample inside it when a laboratory tries to make an MRI image of a battery cell.
This image shows a high strength magnetic field solenoid with a small battery placed inside it that has a problem of sparking at the coil which destroys the coil and the battery.
Their solution is to position the battery being tested in a sealed metal disk-shaped container with a second circular metal sensor disk at the opposite end of the apparatus.
This testing is done to determine the cyclic insertion and extraction of lithium in a carbon mixture that is currently used in commercially available lithium-ion batteries by 7Li NMR spectroscopy under actual operating conditions.

We see how sakis1 said his modification can be explained by looking at the google images for NMR and MRI.
But all of the NMR and MRI images I see require a strong magnetic field that cannot be produced by the 9v batteries we see in a portable pistol locator.
NMR and MRI detectors require very high magnetic fields that are not found from common magnets.
This makes me think that the modification sakis1 made is not working from NMR principles.
I think his modification is working from a different principle than MRI or NMR.
Maybe sakis1 can show us more about his modifications so we can see some details to know what he did to change from the original metal locator that I posted above.
