- aThe number of species with CVs greater in the respective method or ion
- Note that comparison for ions were made using peak areas, while those for smooth versus not smoothed utilized peak heights. Note that negative ion mode had an injection with a different volume than the remaining injections, and hence this could be the reason for increased CV as compared to positive ion mode
