Comprehensive Solution for Increasing
Bioseparation Efficiency
Adsorption of biomolecules can occur not only within instruments, but also in vials, columns, and other equipment Selecting Analytical Columns Based on Target Components and Objectives
used during sample preparation. Shimadzu offers support for resolving such issues with products that feature unique
Shim-pack Series Columns
™
technologies for inhibiting adsorption.
Analyzing biomolecules, such as proteins and nucleic acids, requires using columns intended for a variety of separation
modes. In particular, samples sensitive to metal ions require a column that is optimized to reduce adsorption.
Shimadzu offers columns optimized for a wide variety of molecules.

TORAST-H Bio Vials
Biomolecules are most likely to adsorb to vials they contact the longest. TORAST-H Bio vials offer exceptional resis-
tance to adsorption by biomolecules, which helps maximize recovery rates from valuable samples and increase
sensitivity for analyzing trace components.
