3 Signs Your Glass May Be Causing Test Errors

SilcoNert coated glass Y connectors

If you're having problems getting adequate results from your GC or sample system, it may not be the machine, or your method.  It could be glass surface reactivity.  Here are 3 signs your glassware is not up to par.  

  • Reduced signal loss.  Losing sample compounds?  It could be adsorption/reactivity of the liner or other glass surfaces in the sample flowpath.
  • Peak tailing.  Reactive liners can interfere with resolution and peak quality.
  • Sample carryover.  Analyte (especially proteins) can stick to reactive surfaces, then contaminate other samples.

Vials, inlet liners, Y connectors and all reactive surfaces can be made inert and resistant to carryover by applying an inert coating like SilcoNert® 2000 or Dursan®; helping to achieve the lowest levels of detection, improved liner performance and inertness for common test methods and compounds:

  • Chlorinated pesticides (EPA 8081)
  • Semi-volatile Organics (EPA 8270)
  • OP pesticides
  • Ammonia NOx and SOx
  • Sulfurs

SilcoNert® and Dursan® improve system response by up to 50% compared to other glass deactivations.

SilcoNert prevents surface adsorption

SilcoTek® makes it easy to fix common activity related problems.  We offer quick glassware, vial, and liner deactivation service, the process easy!   You'll get a problem free inert flowpath in 10 business days or less.
