Pure CO/carbon monoxide gas cylinder seems ideal

I was set on SN but high ppm concentration CO in a small tent seems ideal

If I get a 5L or similar small tank of 99. 9% pure CO gas,that's basically a million ppm which seems like more than enough to almost immediately CTB painlessly in a small,sealed tent without the need for burning charcoal and the stress that would cause me

Can anyone chime in here if I'm missing something? Its 600 bucks for the cylinder and another 400 for the 10,000 ppm 707 co monitor but that seems more than worth it
10000 ppm calibration gas seems almost as effective and is much cheaper , a 103 liter tank of 10k ppm would surely be adequate for filling even a larger space for enough time to CTB

Seems pretty straightforward to aquire CO at a high PPM providing you don't need it delivered, delivery from the online retailers seems to require a legit business address but it may be possible to skip that by picking up in person from places that sell it

10k ppm should be pretty damn lethal, very quick and painless (12k ppm supposedly kills in 3 minutes) and you can get large amounts of it for barely 100 bucks. I'll update if/when I pick up my tank
