The Column: Tips &Tricks GPC/SEC: Strategies to Save Solvent
Tetrahydrofuran (THF) — a widely used solvent in gel permeation chromatography/size-exclusion chromatography (GPC/SEC) — is set to be classified as carcinogenic as proposed by the Committee for Risk Assessment (RAC). Analytical laboratories therefore need to find ways to reduce THF solvent use and waste, far beyond the demands of green chemistry. This instalment of Tips & Tricks presents different strategies to meet this goal. |
