![]() Stoddard Solvent StandardStoddard 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 separately. This standard is dissolved in methanol for analysis by either direct injection or purge and trap. View Product Information |
![]() Mineral Spirits Standards (Unweathered)We prepare our solutions from an equal volume blend of Type I, II, and III mineral spirits. View Product Information |
![]() Fuel Oil Degradation Mix (4 components)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.

![]() Fuel Oil #6 StandardThis fuel, sometimes called bunker C or residual, is a black viscous oil. Applications in which it may be used require the ability to preheat the fuel prior to pumping and burning. View Product Information |
![]() Fuel Oil #5 StandardFuel oil #5 is typically used in applications in which there is little or no preheating of the fuel prior to burning. A blend of distillate (fuel oil #2) and residual (fuel oil #6), the fuel oil #5 used to prepare this mixture has a kinematic viscosity of 106.5 at 38°C (100°F), measured using ASTM D-445. View Product Information |
![]() Fuel Oil #4 StandardFuel oil #4 is typically used in limited applications in which the fuel cannot be preheated prior to burning. The fuel is a blend of distillate (fuel oil #2) and residual (fuel oil #6) to meet ASTM viscosity specifications. Fuel oil #4 used to prepare this mixture has a kinematic viscosity of 21.9 at 38°C (100°F), measured using ASTM D-445. View Product Information |
![]() Used Motor Oil Composite StandardPrepared from an equal volume blend from five gasoline powered vehicles (belonging to Restek employees). After blending, a precisely weighed amount of the composite is added to a volumetric flask to produce the standard. View Product Information |
![]() Motor Oil Composite StandardPrepared 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. View Product Information |
