Table 2.
Analyte properties including structure, vapor pressure (VP; at 25 °C), relative sweetness to sucrose, drift times, and reduced mobilities for 50 ng deposits of specified sugar alcohols at base case instrument conditions (Table 1). Drift times and reduced mobility values represent the preliminarily assigned chloride adducts. Vapor pressures were estimated using EPI Suite v4.11, US EPA, 2014.
