CHROMABOND® HR-Xpert

The professional concept of innovative SPE phases.

The CHROMABOND® HR-Xpert concept comprises 5 polymer-based RP and mixed-mode ion exchange phases. Depending on the character of the analytes it offers suitable adsorbents and optimal methods for sample preparation, cleaning and concentration.

State-of-the-art spherical polymer:

• Particle size: 85 μm
• Broad spectrum of application with special suitability for enrichment of pharmaceuticals from biological matrices
• Ideal flow properties due to low content of particulate matter

Optimized pore structure and high specific surface:
• High loadability and outstanding elution properties in RP as well as mixed-mode
• Low solvent consumption
• Rapid, economical analyses

High purity adsorber material:

• Allows high reproducibility with extremely low blind values
• Reliable analyses at ultra trace level
• No method adaptation for new batches necessary
