Core Shell Columns

Maximize LC Separation Performance with Core Shell Technology

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 g improving separation and detection
Faster separation without sacrificing performance g maximizing laboratory productivity and reducing cost of analysis
Increased sample throughput g reducing overall analysis time
Superior ruggedness g reducing cost of analysis
Excellent reproducibility g 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.

Prominence Prominence-i plus Nexera XR Nexera-i plus Nexera X2
LC System HPLC UHPLC-like UHPLC
Particle size 2.7 µm & 5 µm 2.7 µm 1.8 µm & 2.7 µm
Column I.D. 4.6 mm (3.0 mm) 3.0 mm (2.1 mm) 2.1 mm
Column Length 100-250 mm 50-100 mm 150 mm
