Semi preparative columns with inner diameters of 6 – 8 mm are the ideal choice when scaling up from analytical HPLC to preparative chromatography. They provide higher loading capacity than standard analytical columns while maintaining excellent resolution and reproducibility. This makes them perfectly suited for method development, compound purification in milligram to low-gram scale, and preparative workflows where sample availability is limited.
Dr. Maisch semi prep columns combine robust hardware with high-quality stationary phases, ensuring sharp peak shapes, long lifetime, and cost-efficient operation. They serve as a reliable intermediate step between small-scale analysis and large-scale preparative runs, allowing laboratories to optimize methods before transferring them to full preparative hardware.
Flexible options for scale-up. Our semi preparative columns are available in standard inner diameters of 6 mm, 7.8 mm, and 8 mm, offering the ideal balance between loading capacity and resolution. Designed as a bridge between analytical and full preparative formats, they provide reproducible performance across a wide range of purification tasks.
Optimized performance at mid-scale. Our professional packing service ensures uniform bed density, sharp peak shapes, and reproducible results for semi preparative columns (6 – 8 mm ID). By extending column lifetime and minimizing downtime, we provide a cost-efficient solution for reliable scale-up and purification workflows.
