OK.. scouring this damnedable report to figure out what they're trying to say about TSNAs, I *think* that they tested for each one at varied detectable levels. For instance, N-nitrosoanabasine (NAB) was detectable at 21 ppb. They are essentially saying that the njoy cartridges had at least 141 parts per billion TSNAs. Oddly, the control in the tests (the Nicotrol inhaler) shows no results at all. According to the key, this means that the sample was not available for testing. There doesn't seem to be any explanation given for its absence.
So, according to this report, njoy's cartridges contained at least 141Ng TSNAs, while Health New Zealand found 8Ng in 16mg nicotine solution from Ruyan. That's a huge disparity, especially taking into account that the Smoking Everywhere cartridges were found to contain anywhere from 0Ng to 99+Ng TSNAs. It's pretty obvious that the liquid from each company is different.
However, to maintain perspective, 1230 ppb TSNAs in unburned cigarette tobacco.
