2. ULTRA-ALLOY™ STAINLESS STEEL CAPILLARY COLUMNS: The inertness of Ultra ALLOY™ stainless steel columns matches that of fused silica and is derived from a patented, multi-step manufacturing process which utilizes a five-layered pretreatment of the inner surface of the stainless steel. High temperature stability Highly inert deactivated inner surface Exceptional mechanical durability-cannot break! Perfect for field use or high vibration situations Can be tightly coiled (3 inches) for portable GCs Ideal for use in small, field portable GCs Each layer is chemically stable at elevated temperatures and has equaled to, if not superior, mechanical properties to that of the steel tubing. The layers are less than 0.01 microns thick and are chemically bonded together. Stationary phases are then easily bonded to this stable inert surface resulting in superbly deactivated columns which compare directly to fused silica columns.
