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.

Motor oil composite (64742-65-0)
Motor Oil Composite Standard
Prepared from an equal-volume blend of 5W30, 10W30,
10W40, and 20W50 motor oils. After blending, a precisely
weighed amount of the composite is added to a volumetric flask
to produce the standard.

Used motor oil composite (64742-65-0)
Used Motor Oil Composite Standard
Prepared from an equal-volume blend from five gasoline-
powered vehicles (belonging to Restek employees). After blend-
ing, a precisely weighed amount of the composite is added to a
volumetric flask to produce the standard.
