Supercritical Fluid Solubility Measurement System

Model: HPA-SM

The proposed FLOSN HPA-SM uses a dynamic saturation method for compatible low-volatility solutes in supercritical CO₂. A cooled feed pump, serial saturators, temperature-controlled pressure reduction and tandem collection traps support timed sampling with solvent totalization. Collected solute is quantified by a separately validated gravimetric or analytical method. The platform is designed for equilibrium-solubility method development, not a universal solubility detector.

Product Features

6 FEATURES

Serial Saturation Path

Two cartridges provide staged contact and a route for saturation-method checks.

Defined Collection Intervals

Solute collection and solvent totalization share the same accepted time window.

Heated Pressure Reduction

Transfer and back-pressure components are temperature controlled to manage deposition risk.

Tandem Recovery Checks

The second trap provides evidence for assessing breakthrough from the first.

Method-Specific Quantification

Validated weighing, chromatography or spectroscopy can quantify recovered solute.

Transparent Mass-Balance Basis

Reports distinguish recovered mass, CO₂ quantity, concentration basis and recovery corrections.
