Thanks, I did know that is important, but I was curious about the numbers after some posts and thought I'd pass it on if anyone was interested in nerding out on the maths - looks like it was just me - lol.
I tried to compare A4N impurities to our main competitor, but there is no available information on their website or in relevant anns.
Interestingly, they only reach 5N if you round up to 3 decimal places - their impurities were at 12.3ppm on their best sample, which in reality is 99.99877%. So strictly speaking, despite the grandstanding by some, they are still at 4N also.
But maybe that's how it's done in the industry - A4N has done the same rounding up on this table below from last year. The exact level here is 99.997556%.
