ULBON HR-TGC1, Phenylmethyl silicone

Fused silica columns consisting of high purity silica inner surfaces and polyimide outer coatings are widely used as capillary columns. However, these columns were not capable of withstanding high-temperature analyses required for compounds with boiling points higher than 350°C, and were also prone to breaking. Columns with high-temperature polyimide coatings and exterior aluminium coatings have been developed to compensate for these drawbacks, but have been unable to provide heat resistance at analytical temperatures higher than 380°C as well as resolve breakage problems during use.
As a capillary column designed for high-temperature analyses, we recommend a completely internally inert stainless steel column which provides levels of performance equivalent to or surpassing fused silica columns. This product employs stainless steel columns with inner and outer diameters of 0.25 and 0.5 mm, can be subjected to analytical temperatures higher than 400°C, and provides excellent mechanical strength. The ULBON HR TGC-1 is an inert, heat-resistant stainless steel capillary column designed specifically for high-temperature analyses.
