Notes	A mixed standard was prepared in 1 mL hexane (see peak list for nominal concentration of each component). For cleanup, a Florisil tube (cat.# 24034) was first conditioned with 6 mL hexane. The 1 mL standard was then loaded on the tube and eluted with hexane:acetone (90:10), collecting 10 mL of eluent. The eluent was then concentrated down to 1 mL and analyzed.
