96-Sample Parallel BioSPME-DART-MS Platform for Rapid Screening of Fentanyl and its Analogues in Biofluids
Solid-phase microextraction (SPME) with biocompatible coating material is highly compatible with ambient mass spectrometry (AMS), such as direct analysis in real time (DART), for improving sensitivity and reducing matrix effects. However, the practical throughput of SPME−DART-MS remains limited by the mismatch betwee...
