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 a number of the analytes and test conditions used in Shelf Life studies for tobacco products for one testing condition at one timepoint and one replicate.

Row 1:Shows the LBTEST of Product Moisture which reflects the percentage of moisture in the substance for the condition noted in LBTSTCND which is Condition 1 (X°C/ Z% RH). Product Moisture is sometimes referred to as "Oven Volatiles".
Rows 2-12:Show the analytes used in testing.

Please add a row column to your dataset.

*DWB=Dry weight basis. The DWB normalizes the results since starting moisture may vary.


Make sure LOQ is in the dataset - it is important.


A Shelf Life study dataset would shows analytes done in different test conditions with replicates over time points.  In the interest of brevity for this example, only moisture content using the TEST of Product Moisture (also known as Oven Volatile) percentage is shown in a sample of timepoints in two conditions with replicates.

Rows 1-9:Show the LBTEST of Product Moisture for Condition 1 (X°C/ Z% RH) which is shown in LBTSTCND. The sample of various timepoints that may be used in the testing for product moisture is reflected in LBTPT. The LBTPTNUM shows the numerical version of the planned timepoint. The REPNUM shows the incidence number of a test that is repeated within a given timeframe for the same test.
Rows 10-18:Show the LBTEST of Product Moisture for Condition 2 Condition 2 (A °C/ B %RH) across the same timepoints shown for Condition 1. The LBGRPID is used to tie together a block of related records in a single domain.
