Shim-pack Velox LC Columns

Maximize LC Separation Performance with Core Shell Technology

Shim-pack Velox LC Columns

Designed to maximize performance of LC systems, Shimadzu's Shim-pack Velox columns with core shell technology enable you to achieve increased separations and faster analysis times on any LC platform. Whether developing a high efficiency LC separation method, transferring an existing method for increased throughput while maintaining resolution, or are trying to improve the resolution of a complex separation, Shim-pack Velox columns will satisfy your needs.
Column ruggedness is critical to any LC analysis and Shim-pack Velox core-shell columns deliver excellent column lifetime for even the most challenging sample matrices.

Shim-pack Velox column will deliver

  • Increased resolution with maximum efficiency → improving separation and detection
  • Faster separation without sacrificing performance → maximizing laboratory productivity and reducing cost of analysis
  • Increased sample throughput → reducing overall analysis time
  • Superior ruggedness → reducing cost of analysis
  • Excellent reproducibility → maintaining analysis and data integrity

Column Selection Guide for Different LC Platforms

Column particle sizes and column volumes affect chromatography results significantly if the column configuration does not match the LC system. As column particle size is reduced, or the column volume (ID and/or the length of the columns) decreases, the necessity for a lower dispersion system is increased.
Choosing the optimal column configuration for your LC system allows you to achieve improved chromatography. 
The following table summarizes the starting recommendations of column configuration for each LC system.
