Description:

The PL-GPC 220 is an integrated GPC/SEC system that features unbeatable reproducibility for any application, across the entire operating range. An extremely powerful platform, the PL-GPC 220 runs almost all polymer, solvent and temperature combinations, with full automation and advanced detection, from ambient up to 220 °C.
The PL-GPC 220 is designed 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. The solvent module incorporated within the PL-GPC 220 provides a safe, controlled environment to manage solvent and waste. The PL-GPC 220 solvent delivery module houses Pump with integral degasser. The solvent delivery module is temperature-controlled to 30 °C, which ensures efficient, continuous and reproducible solvent delivery, even if the solvent is viscous or solid at near-ambient temperature. The multi-heater, forced-air oven within the PL-GPC 220 is extremely stable, and accurately controls the temperature to less than 0.05 °C per hour. This minimizes detector baseline drift, ensuring the reproducible retention times so important in GPC. The oven in the PL-GPC 220 comfortably holds six, standard 300 mm, GPC columns. The oven opens at a convenient angle to provide easy access for changing columns and the injector loop, delivering comfortable and safe operation. The improved Refractive Index (RI) detector includes an enhanced photodiode and uses fiber optic technology to maximize sensitivity while minimizing baseline drift and noise, vital for good GPC/SEC. This RI detector delivers outstanding signal-to-noise ratios, even at 220 °C. Dual-zone heated autosampler accommodates 39 samples in industry-standard 2 mL vials. Injection precision is better than 1% RSD with no cross contamination between samples, and without the need for rinse vials. The PL-GPC 220 autosampler design features dual-zone heating to minimize thermal degradation. The hot and warm zones are independently programmable from ambient to 220 °C. Integral sensors monitor the system constantly. Vapor sensors are fitted in both the solvent module and column oven. The sensors can be programmed for sensitivity according to the solvent in use.
