CromCarb™ Select

The Future of Reverse Phase Chromatography

High-efficiency, silica-free chromatography for small molecules, complex analytes, and method innovation.

Overview

Why the Next Generation of Chromatography Demands Pure Carbon (Put a carbon icon beside this)

As analytical and preparative demands intensify across pharma, chemicals, and environmental sciences, conventional silica-based reverse phase materials are reaching their limits.

CromCarb™ Select, built on cutting-edge graphitized carbon microbeads, overcomes the inherent weaknesses of silica phases — delivering robust chemical stability, exceptional polar and nonpolar retention, and unwavering reproducibility even under the harshest mobile phase conditions.

Derived from advanced NanoPak-C carbon platform technology, CromCarb™ Select empowers scientists to achieve sharper, faster, and more sustainable separations — unleashing a new era of chromatographic performance.

Technology Platform

Advanced Graphitized Carbon Microbeads — Built for Performance Without Compromise

CromCarb™ Select utilizes precision-synthesized all-carbon microspheres formed through a proprietary eco-friendly microfluidic process.
Key attributes include:

  • 100% Pure Graphitized Carbon Framework: No silica, no ion suppression risks

Performance Features

Performance Redefined by Carbon Innovation

No Phase Collapse Under Aqueous Conditions

  • Traditional silica C18 phases dewet and collapse in high aqueous environments.
  • CromCarb™ Select retains structural integrity — enabling full-range aqueous gradients and improved early-eluting compound resolution.

Outstanding Retention of Polar and Nonpolar Analytes

  • Harness π-π interactions, dispersion forces, and hydrophobic retention — in a single platform.
  • Ideal for isomer separations, highly polar pharmaceuticals, and complex impurity profiles.

Accelerated Method Development

  • CromCarb™ Select tolerates rapid pH swings and high-temperature gradients, allowing for aggressive scouting runs.
  • Enables faster scale-up and validation workflows.

Sustainable Separation

  • Lower solvent consumption due to faster equilibration and longer column life.
  • Supports green chemistry initiatives by minimizing hazardous solvent disposal.

Application Segments

Where CromCarb™ Select Excels

  • Pharmaceutical QA/QC: Consistent retention of polar impurities, degradation products, and isomers.
  • Environmental Analysis: High durability under complex soil, water, and biological extract matrices.
  • Fine Chemical Separations: Process-resilient chromatography for intermediate purification and quality assurance.
  • Lipidomics and Metabolite Profiling: Retains nonpolar lipid species and polar metabolites simultaneously.

Example:
GLP-1 analog separations under pH 8.5 mobile phases demonstrated >20,000 plate counts with CromCarb™ Select — outperforming traditional silica columns over time​.

Commercial & Operational Benefits

Beyond Performance — Building Sustainable, Scalable Workflows

  • Extended Column Lifespan: Carbon structure resists acid/base and temperature damage — 2x–5x longer life than silica equivalents.
  • Lower Total Cost of Ownership (TCO): Fewer replacements, lower solvent waste, reduced maintenance costs.
  • Scalable from Analytical to Preparative: Available across formats — HPLC, Flash, Prep — simplifying technology transfer.
