New Integrated GPC System: affordable and reliable Polymer Characterisation PL-GPC 50 Plus

The new, enhanced PL-GPC 50 Plus is a high resolution, cost effective integrated GPC system designed for operation from ambient to 50°C. The standard system comprises a precision solvent delivery system, a sample injection system, a high performance differential refractive index detector and a column oven, with fully integrated software control. For maximum flexibility and applicability, a choice of system enhancements is also available, modules for:

The enhanced PL-GPC 50 Plus platform enables fully integrated triple detection, including refractive index (PL-RI), viscometer (PL-BV 400RT) and light scattering (PL-LS) detectors. Additional detector options (UV and ELSD) and combinations are available, supported with integrated software control and processing.

Designed for Ease of Use
The PL-GPC 50 Plus features onboard PC-based system control and Cirrus™ data acquisition and analysis software - everything you need to get up and running in one integrated package. The simplicity of the PL-GPC 50 Plus design and the intuitive interface make it extremely easy to operate. This, combined with high performance and reliability, makes the PL-GPC 50 Plus the ideal choice for any laboratory.

Advantages Over A Modular System
The PL-GPC 50 Plus integrated system has several advantages over a modular system in that it is easier to operate and control, and is highly stable and very robust to changes in ambient conditions. A comparison of the baseline drift of the PL-GPC 50 Plus at 40°C and a typical modular system at room temperature demonstrates that the drift of the PL-GPC 50 Plus is less than 1mV in 4 minutes compared to a drift of nearly 3mV on the modular system resulting from changes in the ambient temperature of the laboratory.

Versatility and Performance
For optimized performance, the system is designed to significantly reduce extra column dispersion and band broadening effects, thereby maximizing resolution and accuracy for the GPC separation. The PL-GPC 50 Plus can accommodate up to four regular 300mm GPC columns with easy access for column exchange via the hinged front panel. The RI detector exhibits both high sensitivity and excellent baseline stability for a wide variety of organic GPC and aqueous based eluents.

Excellent Reproducibility
The flow rate precision of the solvent delivery system is fundamental to achieving the most reliable GPC data. The PL-GPC 50 Plus delivers flow reproducibility of better than 0.07%, resulting in repeatable calibration curves and accurately calculated polymer molecular weight data.
