Scientific Background

Efflux solves mechanistic models of liquid chromatography by combining mass-balance PDEs for column transport with kinetic or equilibrium binding models. This section covers the mathematical foundations behind each component of the simulation.

Mechanistic Modeling

An overview of mechanistic chromatography modeling. What it is, why it matters, and how Efflux uses first-principles PDEs to predict separations.

Unit Operations

The building blocks of a chromatography simulation. Sources, columns, reactors, and detectors - and how they connect.

Column Models

Mathematical models describing solute transport and separation in chromatography columns, from detailed mechanistic to simplified representations.

Binding Models

Adsorption isotherms and kinetic models governing how solutes interact with the stationary phase.

Simulation

DAE formulation, time integration, phase-based simulation, and how the solver assembles and advances the system.
