Capillary Column

In the most basic level, a capillary column is composed of two parts - the tubing and stationary phase (Figure 3). Fused silica and stainless steel are the primary tubing materials. There are numerous stationary phases. Most are high molecular weight, thermally stable polymers that are liquids or gums. The most common stationary phases of this type are the polysiloxanes (sometimes incorrectly called silicones) and polyethylene glycols. The next most common type of stationary phases are small, porous particles composed of polymers or zeolites (e.g., alumina, molecular sieves).
