In gas chromatography, inert surfaces in the flow path from the inlet through the column to the detector are essential for achieving good peak shapes, low-level detection, and accurate results for active analytes. Active analytes that stick to exposed silanols and other chemically active sites in the flow path include: organic acids and bases, sulfur species, alcohols, amines, aldehydes, phenols, and pesticides. Accurate and reproducible measurements of these analytes play important roles in international commerce, product quality, environmental preservation, and human health risk assessment for consumer products and foodstuffs.

A flow path diagram is a very useful tool in understanding where and how a lack of inertness can negatively impact chromatography. Remedies for avoiding potential pitfalls in the various sections of the flow path are displayed with a flow path diagram as the backdrop. Five tips for achieving the most inert GC flow path possible are discussed. Recent innovations and new tools enabling further inert flow path enhancement are covered.

Participants Will Learn:

• Inertness: what it means and where it is most important

• Flow path diagram, activity focal areas

• Five tips to optimize inertness

• Inertness testing and its significance

• Real life examples showing the importance of inertness

• Essential tools for your inert flow path
