Solid Phase Extraction (SPE) remains one of the most trusted techniques for isolating, purifying, and concentrating analytes prior to chromatographic analysis. As a result, labs across environmental, pharmaceutical, and food‑safety sectors rely heavily on consistent, high‑performing cartridges. Macherey‑Nagel’s C18 SPE cartridges, distributed through Sorbtech, are specifically engineered to deliver exceptional reliability, purity, and extraction efficiency.

Moreover, these cartridges are built on high‑purity silica and optimized octadecyl (C18) chemistry, which together ensure strong hydrophobic retention and stable reversed‑phase performance. Therefore, whether your workflow involves complex matrices or routine QC samples, these cartridges offer the dependable results modern labs demand.


Engineered Silica and Optimized C18 Chemistry for Strong Retention

Macherey‑Nagel C18 cartridges are manufactured using high‑quality silica that offers excellent surface area and uniform particle distribution. Consequently, analytes interact consistently with the sorbent, producing reliable retention and predictable elution profiles.

The octadecyl‑bonded (C18) phase provides robust hydrophobic interactions, making these cartridges ideal for trapping:

  • Non‑polar molecules
  • Hydrophobic organic compounds
  • Pesticides and environmental contaminants
  • Lipophilic pharmaceuticals

Additionally, because these cartridges are designed to accommodate secondary interactions with moderately polar analytes, they deliver enhanced flexibility and better selectivity across mixed‑composition samples.


Versatile Cartridge Designs for Flexible Lab Workflows

Macherey‑Nagel offers their C18 SPE sorbent in multiple cartridge formats, allowing seamless integration into nearly any lab environment. For instance, the Chromabond® column‑style versions support traditional SPE manifolds, while the Chromafix® Luer‑tip cartridges are tailored for positive‑pressure workflows.

Furthermore, these cartridges are available in a wide range of sizes, including:

  • Compact cartridges for small‑volume samples
  • Medium‑volume formats ideal for routine testing
  • Large‑volume, high‑capacity cartridges for environmental and industrial applications

As a result, laboratories can choose the exact volume, sorbent mass, and format needed for their workflow — from manual syringe‑based extraction to automated robotics‑driven sample prep systems.


Ideal Applications for Macherey‑Nagel C18 SPE Cartridges

Because these cartridges deliver strong reversed‑phase retention and high‑purity silica performance, they excel in demanding analytical situations. To illustrate, C18 SPE cartridges are well‑suited for purifying and concentrating a broad range of analytes, including:

  • Environmental pollutants (PAHs, PCBs, pesticides)
  • Pharmaceutical ingredients and metabolites
  • Drugs of abuse and toxicology markers
  • Vitamins, preservatives, and food additives
  • Hydrophobic compounds requiring selective reversed‑phase purification

Ultimately, these capabilities make Macherey‑Nagel C18 SPE cartridges a versatile, go‑to option for laboratories requiring both sensitivity and reproducibility.
