upon review of the following article Measuring Nitrogen Gas in Beer by Karl Ockert

http://www.mbaa.com/brewresources/brewpedia/BrewPosts/A%20way%20to%20measure%20N2%20in%20beer.pdf

as well as review of past discussions on the topic i have a few detailed questions

1. the article mentions using 23psi head pressure, nitrogen, and time. forum comments mentioned the same thing but pressures varied. Is it standard practice to carbonate the beer to around 1.8 to 2.0 VOL. C02 ahead of this process?
2. About how long does the above infusion process take at the mentioned 23 psi? does the process occur faster at higher pressures? (above 30psi was mentioned)
3. In the articles calculation section, it mentions 24.1 as the adjusted molar volume yet in the calculation examples its shown as 22.4 which is correct?

thank you in advance.

We do quite a bit of nitrogenation in our brewery. What we found that works the best is getting the beer as cold as possible (~31F-32F), pressurizing headspace to ~25 psi, and then sending nitrogen through carbstone to achieve 30 psi head pressure. The low temp and the high pressure do wonders. All of our tanks are 2 bar working pressure.

Also, forgot to mention that we infuse with pure nitrogen instead of beer gas.
