NPS

NPS is a common abbreviation referring to a Non-Polar Solvent.

Non-polar solvents are solvents comprised of molecules with insignificant electromagnetic properties. This regards the use of solvents in terms of their miscibility in relation to one another and the solubility of solutes in relation to solvents. Generally, like dissolves like, as in solvents are miscible in similar solvents.

In extraction, non-polar solvents are generally characterized by their ability to dissolve freebase alkaloids and separate from water, as water is a highly polar solvent.

Commonly used non-polar solvents in extraction include:

• Naphtha
• Xylene
• Toluene
