CORESTA 2009 Reference Products - 2019 Analysis

TTPA Technical Document

July 2020 Ref. TTPA-219-1-CTR

The CORESTA Tobacco and Tobacco Products Analytes (TTPA) Sub-Group initiated an inter-laboratory study designed to assess the stability of the four CORESTA Reference Products (CRPs) manufactured in 2009. Participating laboratories reported the levels of nicotine, pH, moisture (oven volatiles), tobacco specific nitrosamines (TSNAs) in the CRPs using CORESTA Recommended Methods (CRMs). The data were evaluated for stability by examining trends over time in the analyte levels and measures.

The results from this 2019 stability analysis of the 2009 CRPs generally compared well to the stability analysis for the 2009 CRPs last conducted in 2015, thus demonstrating that the products are stable when held at the recommended storage conditions of −20 °C.
