Описание: High-temperature Gas Chromatography applications using fused silica columns can be problematic for applications that run above 360°C. Even if a phase is stable enough to maintain extended periods of time above 360°C, the polyimide coating on fused silica will eventually burn off, causing the column to become brittle. We will examine what affect temperatures above 360°C will have on the integrity of the column phase and brittleness of the column over extended periods of time. We will also look into strategies for more efficient and successful high-temperature applications, such as utilizing metal columns, and how long they are able to operate at temperatures up to 450°C and still maintain their integrity. We will also discuss how selection of the right consumables and maintaining a leak-free system is especially important in high-temperature GC applications, and how to pick the right ones to have a successful and robust GC analysis.
