Shelf life study has a protocol and provides the results of shelf life studies of tobacco products over time with different conditions and analytes. Generally there are many conditions with at least two with varying temperature, humidity, etc.
The initial table shows the all the analytes and test conditions.

*DWB=Dry weight basis. The DWB normalizes the results since starting moisture may vary.
Make sure LOQ is in the dataset - it is important.
The shelf life study dataset shows analytes done over replicates over time points. In the interest of brevity in an example, this only shows the moisture.
