ASTM D2887-12 Calibration Standard (20 components)

More Details
Designed to serve as a column resolution text mixture, as well as a calibration mixture for retention time (RT) versus boiling point (bp) calibration.

D2887 Calibration Mix (17 components)

More Details
These calibration mixtures are made with pure, highly characterized neat material and are prepared using NIST-traceable balances and weights. Each ampul is supplied with a data sheet indicating the exact concentration and a sample chromatogram.

NOTE: The D2887 Calibration Mix is a weight/weight % blend of short-, medium-, and long-chained alkanes that requires special handling to ensure accurate transfer and analysis. Restek recommends heating the sealed ampul for 3 minutes at 100 °C (212 °F) to completely liquefy the sample. Invert the ampul several times to homogenize the contents and then open, transfer, and dilute (per your application) within 1 minute of heating.

Polywax Standards

More Details
Supports ASTM Methods D2887, D6352, D7169, D7398, and D7500.

These high molecular weight hydrocarbon waxes are useful for simulated distillation and other high-temperature GC work.
