Last month, this company launched a new range of SOLA solid-phase extraction (SPE) cartridges and plates. SOLA combines polyethylene frit materials and stationary phase components into one, uniform entity. As a result, these cartridges and plates deliver “superior” reproducibility, recovery and sensitivity, and reduce the levels of contaminants and extractables within the eluate, says the manufacturer. The uniform stationary phase of SOLA cartridges and plates is said to be a significant advancement on traditional SPE formats, in which loosely packed, powdered silica or polymeric materials are positioned between two polyethylene frits. This new, robust design eliminates issues such as voiding, channeling and packing inconsistencies, says the company. — Thermo Fisher Scientific Inc., Atlanta, Ga.
