What are some common causes of peak fronting? - WKB255705

Article number: 255705

ENVIRONMENT

Common causes include:

Mass overload (too much mass in each injection)
Column void due to packing material dissolution or bed collapse
Volume overload (too much sample volume injected)
Poor connection somewhere in the flow path between the injector and the detector:
- If using PEEK fittings, the tubing can slip if the PEEK finger-tight fitting does not grip the tubing strongly enough.
- If using stainless steel fittings, ferrule depth may be too short and a new connection may need to be made.
