Agilent has designed the PL-GPC 220 for truly unattended operation. The system gradually heats to the analysis temperature while the pump maintains a low flow of solvent through the column. Once the set temperature is reached and stable, the pump ramps gradually to the full analysis flow rate. at which point the PL-GPC 220 automatically purges and zeros the RI detector. Detector output is monitored and, when stable, the autosampler loads and injects the first sample. Once the run sequence is complete, the flow rate can be automatically reduced to conserve solvent. The PL-GPC 220 system for polymer characterization up to 220 °C features intuitive, comprehensive PC software control for fully flexible system management. With safety a prerequisite, our instrument control allows location of your PC outside of the laboratory.
