SPE cartridges & columns

C18, a reversed phase, retains non-polar compounds from aqueous matrices. A hydrophilic-lipophilic polymer phase covers a broad range from polar to non-polar and tolerates running dry. Ion exchangers retain charged compounds. Silica, diol, magnesium silicate or alumina, the normal phases, retain polar compounds from non-polar solvents. Mixed-mode phases combine reversed phase and ion exchange for difficult matrices. Start from your analyte and matrix; compare phases in SPE cartridges and columns. Questions about a specific product?

The sorbent mass determines capacity: the amount of analyte and matrix the cartridge can hold is a fraction of that mass; check the product page. The column volume determines how much sample you can load at a time. Small cartridges suit small samples and low solvent use; larger ones suit bigger or dirtier samples. Test the load on a pilot sample first. See SPE and sample preparation. Unsure which one fits? Ask sales@luminixhealth.com.

A vacuum manifold with a valve per position lets you process several cartridges in parallel and control the flow of each. You also need a vacuum pump or water jet pump, plus adapters, caps and reservoirs to load larger sample volumes. Collection racks inside the manifold hold your tubes during elution. A trap between manifold and pump protects the pump from solvent vapour. Pumps are in vacuum pumps. Need advice for your set-up? Mail sales@luminixhealth.com.

A typical method runs through conditioning the sorbent, equilibrating it with a solvent similar to the sample, loading the sample, washing to remove matrix, drying if the method requires it, and finally eluting the analyte. Keep flow rates steady and do not let the sorbent run dry unless the phase allows it. Follow the method for your phase; see SPE and sample preparation.

An SPE cartridge holds a bed of sorbent. Bed mass, sorbent chemistry and volume are the specification. A 100 mg C18 cartridge and a 1 g C18 cartridge take different sample loads and different elution volumes. The method names all three.

Solid-phase extraction holds a compound on a sorbent while the rest of the sample is washed away, then releases it in a small volume. The sorbent, the bed mass and the solvents are the method. Silica, ion exchangers and polymer phases do different jobs. A flash column is the same idea scaled toward purification rather than trace cleanup. The molecules are on PubChem, named by IUPAC.
