Dry nitrogen is purged onto the surface of heated samples to rapidly evaporate and separate organic solvents, realizing oxygen-free concentration and protecting sample purity. The integrated heating block rapidly heats samples to target evaporation temperature; nitrogen flows through the gas manifold and stainless steel needles to blow across liquid surfaces for accelerated solvent evaporation and sample concentration.
