Part 1: Determine TR'

Build a methanol-based mixture from equal-concentration stock solutions of 1-pentanol, 1-hexanol, 1-heptanol, and 1-octanol. The app generates a synthetic GC trace with an air spike reference, a methanol solvent front, and retention data for the selected analytes.

Part 1

Prepare the injection

Do not exceed 10 mL total.

Every stock solution is 50 mM in methanol. Turn individual solutions on or off, adjust their relative mix parts, and then inject the combined sample.
