Finally a simple method for the realitive purification of NOS

Well im not sure how much everyone here will respect this, im sure at least someone will...

two older friends of mine have spent many years working on the ulitmite method for home purification of racing grade nitrous oxide "nitrous plus." It contains technical grade N2O and SO2. The original design was massive, 6 stages of chemical purification at a high pressure, first 4 stages were NaOH then a bicarb and finally a distiled h2o column. the nitrous that came out was very clean as far as we could tell, in other words it smelt perfectley clean, had no after effects etc.

well i was introduced to the project and i had to make some improvments on it. the high pressure was combined with co2 to recondense the nitrous (after a moleculer sieve for water removal) back into clean nitrous tanks for future use. this was a very elaborate set up that cost a lot to make.

so one day a light bulb clicked on in my head. and this is what i came up with. i want to make it very clear that i have not done any checmical analysis on the product, i dont know its true purity, either way im totally and completley happy with the results. at least 20lbs of nitrous have been done using this technique with no problems.

i took a gas mask filter and pushed it up against the nozzle of the tank. i then put a plastic bag over the output of the filter and SLOWLY filled it up. success! and it tasted perfect, not a complaint!

I went ahead to make the ultra simple $7 version (im well aware of possible improvments, im not discussing the radiator version with the regualtor and so on). I took a garden hose quick connect, a gas mask filter and a barb w/ thread.

and this is what i got.


a littel bit of epoxy and the whole thing came together in the 5 minutes it took for the epoxy to set. its a truly beautiful set up that anyone could make.

i just wanted to share it with everyone and ask if there are any possible contaminets that could be produced by the purification process.

I consider NOS a truly madscientist drug, mostly because of the experience i have had with it lol. im sorry if this thread angers anyone, or if ive overlooekd some dangerous checmial reaction that will eventually kill me and anyone who trys this

inother words, dont anyone try this at home!

The whole point of amateur experimentation is to try things at home. You can tell us not to but I guarantee you that someone will.

How much gas can be processed with a single filter? It seems like this would be a rather expensive purification method, but I guess that would depend on the concentration of sulfur oxides in the original gas.

definetley not an expensive method! thats the whole point! THe filters cost anywhere from 5-15 american dollars, the quick connect is a little over a buck and the barb fitting is 1 or 2 more dollars.

my friend (who does nos much more than i) has goen through easily 80lbs of nitrous in one weekend with one filter with out any problems. hes been using the same one since the begining and there is no detectable difference in the quality of the product!

the concentration of SO2 is 100ppm. the bottle reads that exactly and ive never heard of them putting h2s in the bottles, i would think legaly they would have to change the label on the bottle anyway. NEVER BREATHE IN THE FIRST BALOON! ALWAYS TEST IT BY SMALL SMELLS FIRST!!!!

NOS's web site has a number you can call to find your nearest distributor. a bottle cost about $50 on craigs list and a 10lb refill is around $50. 10lbs will last one person at least 4 hours of continuous use. each punching bag is only like 1/10 of a lb (that would be about 1 mole of gas) so 10lb can do roughly 100 ballons.

i had zero problems with the NaOH method, trust me it was beautiful. i think my friend still has it ill take pictures of it but it may be in pieces. we did use very fine bubblers at the bottom of each 8 foot by 2inch column.

i have yet to open a filter up to see its condition because ive felt no need to. as soon as there is a decrease in quality i will take a look.

im guessing making your own N2O from ammonium nitrate is far more expensive and in large quantities, far more suspicious...

Are you telling me a human inhales half of a normal body weight worth of nitrous through a weekend? That cannot be good pure or not...

Anyways, if you would do something scientific to prove the purity of the gas it might be more accepted around here, like scrubb it and test the scrubber solution for sulfides/sulfites and perhaps change the angle towards purifying nitrous gas and not the actual end usage of such a purified gas. This is as I view it sort of a "how to aquire illicit drugs thread" and as such do not really fit the forum. Though that is just my opinion and I am not the one to request or impose (nor am I able to) censorship on anything as long as it has a scientific "red thread" interwoven...


BTW I feel that there is an increase in direct drug (illicit) related threads popping up lately and though I find the subject very interesting/fascinating I cannot avoid thinking that this might attract unwanted attention from certain swimming individuals...


Edit: HAHA, I saw it now, when I noticed the No. of views that this thread is ancient..

Anyhow, my rant still stands
