Dissolved gases in the solvent can cause bubbles in the flow path of pumps and detectors. Reliable chromatographic separation therefore requires degassing of the solvent. The semiprep 2-channel degasser DG 2.1S is equipped with two degassing chambers and can thus degas two solvents simultaneously. For integration into ASM 2.1L only. Not available as stand-alone device.
