Solve your GC Pain Points.
As regulatory agencies drive LODs lower for active analytes, you cannot afford adsorption caused by flow path activity. For starters, active GC flow path surfaces can cause peak tailing and signal loss, preventing sensitive analytes from being detected. What's more, repeating or re-verifying suspect analyses wastes resources, hinders productivity and hurts your bottom line.  Learn More |
