Abstract

Superficially porous particle (SPP) columns have gained considerable momentum over fully porous particle (FPP) columns among many chromatographers. However, despite several advantages, the SPP columns are not always been used effectively with traditional HPLC. The present study explores the possibility of reducing the runtime of HPLC methods using SPP column technology without compromising the efficiency of high-throughput analysis using conventional HPLC systems. An optimized method was developed by exploiting the advantages of SPP column technology and its effectiveness demonstrated in two separate SPP columns, Kinetex EVO C18 and Accucore C18. By altering method parameters such as flow rate, gradient time, and photodiode array (PDA) detector acquisition rate, we showed that an optimized method is more efficient than the regular method. The experimental results showed significant improvement in peak capacity, peak symmetry, theoretical plate numbers, and peak resolution for the SPP column within a short runtime of 7 min. We demonstrated that the present optimized method helped to reduce runtime by 50% and provide ~ 31% net organic solvent savings, exhibiting a greener approach to methods and method development.
