SPE vs. SPME — Choosing the Right Method
2026 labs often choose between traditional SPE and its miniaturized cousin, Solid Phase Microextraction (SPME).
Traditional SPE: Best for large volume samples and where high concentrations of the analyte are needed. It uses cartridges or 96-well plates and is ideal for pharmaceutical quality control.
SPME (Microextraction): Uses a tiny coated fiber to "sip" analytes from a sample. In 2026, this is the preferred method for Headspace Analysis (smells and flavors) in food science and on-site environmental testing using portable devices.
