 METHAMPHETAMINE. . .on Wipes by Liquid-Liquid Extraction: METHOD 9106, Issue 1, dated 17 October 2011 - Page 23 of 31

Figure 1. Typical chromatograms of chlorodifluoroacetyl derivatives by GC-MS in scan mode

Figure 1a. Extracted ion chromatogram for m/z 156 (155.70 to 156.70). Figure 1b. Extracted ion chromatogram for m/z 170 (169.70 to 170.70). Figure 1c. Total ion chromatogram (TIC). GC Peak Identification: See Table 10 for identification of numbered GC peaks. (But note that retention times in Table 10 do not correspond to those in Figure 1 because a different DB-5 column was used.) GC-MS Conditions: See p. 9106-1 for GC-MS conditions.
