Development, production and international distribution of vials and bottles for chromatography and the pharmaceutical and industrial sectors.
In LC and LCMS separations, tailed peak shapes with basic compounds at high concentrations is a problem commonly observed when low ionic strength mobile phases, such as those using formic acid are employed. A way to improve the peak shape and sample load capacity is to use a stationary phase containing a positive charge. Application examples demonstrating the impact of HALO® positively charged surface (PCS) stationary phases will be presented for small molecules. In addition, the selectivity differences between HALO® PCS C18 and HALO® PCS Phenyl-Hexyl will be highlighted.
