THIOPHANATE-METHYL in air: METHOD 5606, Issue 1, dated 15 March 2003 - Page 5 of 6

Figure 1. This is a typical chromatogram for a sample of thiophanate-methyl. This shows the response for a spike of 348 μg/sample of thiophanate-methyl on an OVS-2 tube, extracted and analyzed by this LC method using the Kingsorb™ column. On the Synergi™ column, the retention time for thiophanatemethyl is 14.1 minutes.



Figure 2. This is a typical chromatogram of a liquid calibration standard. This sample was analyzed with the Kingsorb™ column. The retention time on the Synergi™ column is 14.1 minutes. NIOSH Manual of Analytical Methods (NMAM), Fourth Edition
