Fast Separations for High Turnaround or When Analyzing Many Samples
• Analysis in less than ten minutes saves time • Significantly increased sample throughput improves efficiency • Reduced solvent consumption and disposal costs saves money Two key parameters can be varied to reduce the analysis time of an experiment. Column length can be reduced or eluent flow rate increased. Using both methods, PL Rapide columns provides significantly increased sample throughput compared to a conventional GPC/SEC column set. Rapid GPC is an excellent tool for screening polymer MWD for trend analysis. Short PL Rapide columns reduce analysis times while maintaining the excellent solvent compatibility and mechanical stability of all GPC columns from Varian. PL Rapide columns are ideal for high speed applications such as high throughput screening, process monitoring, or tracking changes in MW distributions, where time is the most critical factor in the analysis. Packed with high quality gels, these columns cover the complete spectrum of molecular weights and are available for the analysis of both organic and water soluble polymers. Key features include high pore volume and high resolution packing materials, no special system requirements, choice of molecular weight resolving range, wide solvent compatibility, and excellent mechanical stability. PL Rapide is available in L, M and H versions for low, medium and high molecular weights. The F version is for flow injection analysis.
