      So, what exactly is a column volume in flash column chromatography and how is it determined?

      In many of my previous posts I have used the term column volume, typically abbreviated as CV, as a value used to help determine separation quality and loading capacity.  However, I recently was asked a question about this topic from a chemist who understands the column volume concept but wanted to better understand its definition and how it is determined.

      In this post I will explain what a column volume is and how it is determined empirically.

      Sfär Stands for Spherical, Biotage® Stands for Quality 

      Biotage developed and introduced pre-packed columns for flash purification in 1994. Today our broad selection of columns enables professionals to choose the solution which best suits their purification needs.

      Sfär is the Swedish word for "sphere", and the name of our columns reflects the fact that we have made spherical silica a standard due to its higher surface area and higher loading capacity. Reliable and flexible, Biotage® Sfär columns deliver larger loading capacities, tighter elution bands and purer fractions than traditional flash columns.
      Biotage® Sfär is a complete portfolio of flash columns, available in a large variety of sizes from 5g to 350 g and in a range of media types, so you can purify milligrams to multi-grams of your valuable compounds quickly and easily.
