💨 Van Deemter Equations (Helium / Hydrogen Carrier Gas Linear Velocity 30-45 cm/sec, Holdup t0)

GC Carrier Gas Linear Velocity Calculator

Optimize capillary gas chromatography carrier gas mobile phase linear velocity (u in cm/sec) and holdup void time ($t_0$) using the Van Deemter equation: evaluate Helium (optimum 30 to 40 cm/s) versus Hydrogen carrier gas (optimum 45 to 60 cm/s for 2x faster run times), calculate inlet head pressure (PSIG), and chromatography throughput profits.
