About Dionex SolEx SPE Cartridges

Dionex SolEx SPE Cartridges extract organic pollutants from a liquid sample off-line using a solid-phase adsorbent. The cartridges employ a variety of chemistries depending on the application. The silica- or carbon-based absorbents are bound or encapsulated in a membrane filter (called disk format), or packed in a cartridge (syringe bodies). Water (ground, waste, and drinking) is the most common liquid sample extracted, but these SPE cartridges are also used to extract contaminants from milk, fruit juices, urine, and other matrices. These cartridges are designed for use with Dionex AutoTrace 280 SPE system or other SPE instrumentation and vacuum manifolds.


Silica-Based or Polymeric-How to Choose?

The decision to choose polymeric or silica-based stationary phase products for SPE is generally guided by pH requirements and relative retention of targets and matrix on the phase. Bonded silica products have a safe operating range generally pH 3-8. The bonded silica phases are generally non-aromatic which means that highly aromatic targets can be more easily eluted with organic solvents. Highly polar targets are generally not well-retained and selectivity among species containing aromatic rings can be limited. These silica phases are generally not mixed-mode.
