Combining the best of the on-line and off-line SPE worlds. Off-line SPE (Solid Phase Extraction) provides cartridge refreshment for every sample, avoiding the risk of retention change and carry-over. However, limited pressure resistance prohibits the use of small sorbent particles. Off-line elution of the sample requires collection and reformatting (often including evaporation and reconstitution) into autosampler vials or wells. And finally… injection into the LC system! It also requires at least one manual transfer of collected samples from the SPE robot to the LC system.
On-line SPE (or column switching, or 2D LC) permits use of small sorbent particles for efficient SPE plus elution of the sample directly into the LC system by the mobile phase. Maximum SPE efficiency plus maximum SPE-LC automation. But…column switching does not allow frequent automated refreshment of the SPE column or cartridge. The Spark ACETM eliminates this shortcoming. It selects a fresh cartridge as often as you want andseals it against the pressure of your LC system for on-line elution. ACETM combines the flexibility of off-line SPE with the performance and automation of on-line SPE.
