The Analytical Scientist / App Notes / 2018 / Metal-Free LC with Dursan® Bio-Inert Coating

Metal-Free LC with Dursan® Bio-Inert Coating

Overview

A bio-inert flow path is required to manage the complex and reactive sample profiles that are common in today’s fast-paced analytical world. Modern LC systems feature an array of exotic materials to achieve bio-inertness, but they are significantly more expensive than instruments constructed with stainless steel flow path components.

Dursan® is a coating for stainless steel that provides equal or better bio-inertness than PEEK along with the durability of titanium. Dursan® is a simple and cost-effective solution for parts requiring bio-inert properties throughout the lab.

Key Features
  • Creates an iron-free bio-inert flow path to minimize unwanted protein interactions and maximize uptime
  • Increases system robustness under extreme salt and pH conditions
  • Improves bio-inertness of frits and other difficult components that cannot be treated by other methods
  • Enhances chemical compatibility, even with media like tetrahydrofuran (THF) that challenge PEEK
