Retention Time Markers
25 µg/mL each in methylene chloride, 1 mL/ampul
cat.# 31200 (ea.)
n-Hexane (C6) (110-54-3)
n-Decane (C10) (124-18-5)
n-Dodecane (C12) (112-40-3)
n-Tetracosane (C24) (646-31-1)
n-Octacosane (C28) (630-02-4)
n-Triacontane (C30) (638-68-6)
n-Tetracontane (C40) (4181-95-7)
Used during initial sample screening to determine retention
time windows for each petroleum product. Gasoline generally
elutes in the window from C6 to C10 (or C12), and diesel fuel
from C10 (or C12) to C24 (or C28). Retention above C24 (or
C28) indicates oil or lubricant contamination.
