Mineral Spirits Standards (Unweathered)
There are four general types of mineral spirits, classified
according to boiling point range (BPR):
• Type I (Stoddard solvent) BPR 149–182 °C
• Type II (high flash point) BPR 177–196 °C
• Type III (odorless) BPR 149–196 °C
• Type IV (low dry point) BPR 149–174 °C
We prepare our solutions from an equal-volume blend of
Type I, II, and III mineral spirits.

Stoddard solvent (8052-41-3)
Stoddard Solvent Standard
Stoddard solvent is also known as Type I mineral spirits,
Texsolve S, or Varsol® 1 mineral spirits. We offer this reference
material for those who need to calibrate Stoddard solvent sep-
arately. This standard is dissolved in methanol for analysis by
either direct injection or purge-and-trap.
50,000 µg/mL in methylene chloride, 1 mL/ampul
cat.# 31464 (ea.)
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.
50,000 µg/mL in methylene chloride, 1 mL/ampul
cat.# 31465 (ea.)
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.
