Automated GX-271 GPC Clean-up System provides an affordable solution for laboratories performing residue analysis of complex matrices such as fatty foods, soils, sludge, animal and plant tissue. The system features a direct injection module and a fraction collection valve located on the Z-arm, increasing efficiency by reducing sample carryover and post valve dead volume. The system is controlled with TRILUTION LC Software, which offers pre-programmed methods specific to GPC post-extraction clean-up processes.
