Notes

• Reconstructed chromatogram from select ions.
• Propargite isomers are only slightly resolved with this method, so they are treated as one peak, but individual retention times are 20.40 and 20.42 min.
• The reference standard is also available as part of Restek’s 200+ compound GC multiresidue pesticide kit (cat.# 32562).
