As there were no masses which were present in only a single sample set, a list of potentially identifying masses is generated for a given brand using the above-mentioned t-tests. A mass is deemed identifying of a brand if for that brand, the mean of the measured intensities is the largest among the five sample sets, and if the distribution of those intensities is statistically significantly different from the other four sample sets. The number of identifying masses are tabulated for each brand at each pH in Table . The distribution of identifying masses across each brand is generally good at an unaltered pH and positive ionization, however, there is only 1 identifying mass each for Glenfiddich 12 and Glenfiddich 18. At pH 7, the analysis appears to favor Glenfiddich 12, with 140 identifying masses. This may be due to the addition of salt from the pH buffer increasing the volatility of compounds in samples from that brand more than from other brands. At pH 10, the analysis appears to favor Gentleman Jack and Glenfiddich 18. At an unaltered pH under negative ionization, there is a vastly decreased number of identifying masses across all five brands
