Different particle sizes are used for different kinds of column chromatography as the particle size is related to surface area. These materials have the ability to remove metal ions selectively from aqueous solutions. Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica gel packs or other products. In column chromatography, the stationary phase is most often composed of silica gel particles of 40–63 μm. A conventional adsorption chiller with silica gel as adsorbent and water as adsorbate has been analyzed numerically. Due to the lack of regulations for domestic water filtration products, no studies validate the manufacturer claims regarding the effectiveness of the filtration system.
