Mineral Spirits

More Details
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

    This standard is manufactured using the Type 1 mineral spirit.

    Note: Cat.#s 31260 and 31261 are produced with CAS# 64475-85-0, a Type 1 Mineral Spirit containing the proper ratio of n-alkanes (higher proportion) and isoparaffins/cycloalkanes (lower proportion). Lots produced prior to March 2017 contained CAS# 8030-30-6, a C10-C13 isoparaffins odorless Mineral Spirit with >98% isoparaffins (branched alkanes/aromatics) and minimal n-alkanes.

Stoddard Solvent Standard

More Details
We offer this certified reference material for those who need to calibrate Stoddard solvent separately. This standard is dissolved in methanol for analysis by either direct injection or purge and trap.

Fuel Oil Degradation Mix (4 components)

More Details
Subsurface degradation of fuel oil spills can be estimated by examining the ratios of C17/pristane and C18/phytane.1 To assist in identifying these four compounds from the complex fuel oil analysis, we offer a product that contains these compounds for retention time determination.
