Molecular Sieves

Molecular sieves come in different types such as 3A, 4A, 5A and 13X. The numeric values define the size of the pore and the chemical composition of the sieve. The ions of potassium, sodium, and calcium are altered in the composition to control the size of the pore. There are different numbers of meshes in different sieves. A molecular sieve with a smaller number of meshes is used to separate gases, and one with more meshes is used for liquids. Other important parameters of molecular sieves include the form (powder or bead), bulk density, pH levels, regeneration temperatures (activation), moisture, etc.
