Why An Inert Flow Path Is Critical To Reliable GC & HPLC Sampling And Testing

An inert flow path will prevent adsorption, contamination and loss of active and reactive compounds in gas chromatography and liquid chromatography sampling applications.  Without inert coatings like SilcoNert® and Dursan®, GC and HPLC systems produce inconsistent or substandard results.  Adding a GC coating or HPLC coating to the flow path will prevent surface to sample interaction, assuring the entire sample is analyzed.  


SilcoNert® and Dursan® Benefits

Uncoated active surfaces result in slow response, costly rework, and process failures. Non reactive surfaces like SilcoNert and Dursan give analysts confidence in the reliability of their sampling system results.  Gas chromatography and liquid chromatography coating benefits include:

  • Eliminate false positive or false negative results
  • Improve process control by eliminating delays in system response
  • Prevent retesting and rework
  • Assure product quality
