Supercritical and Near Critical CO2 Micronization
Supercritical and Near Critical CO2 Micronizer and Atomizer
Micronization systems are designed to produce small, very small particles and nanoparticles. The change in size depends on the technology used. Near-critical Expansion Atomization (NEA) produces 10 to 50 micrometer-sized particles, while Particles from Gas Saturated Solutions (PGSS) and Supercritical Anti-Solvent (SAS) can produce nanometer-sized particles. Supercritical Assisted Atomization (SAA) is a version of SAS that counteracts the decrease in temperature during expansion.
