According to the inert gas megathread:

You will need to keep the inert gas flowing at 15 liters per minute (Lpm) for 40 minutes to be confident of ending your life —in other words, you'll need a minimum of 600 liters of inert gas.

Use Boyle's law to calculate the volume of gas in the 2 L cylinder when expanded to atmospheric pressure:
(200 bar * 2 L)/1.013 bar = 394.86 L

The 2 L cylinder is too small by about 200 L. You would need a 4 L cylinder minimum.
