We report the results of an experimental study of the effect of a dilute silica network on liquid-gas critical phenomena in carbon dioxide (CO₂). Using small-angle neutron scattering, we measured the correlation length of the density fluctuations in bulk (ξbulk) and confined CO₂ (ξconf) as a function of temperature and average fluid density. We find that quenched disorder induced by an aerogel suppresses density fluctuations: ξconf loses the Ising model divergence characteristic of ξbulk and does not exceed the size of pores in the homogeneous region.
