With the GC column PRECIX you can expect the same outstanding quality as with Hamilton's established products like the world-famous MICROLITER™ syringe. The quality assurance starts from the very beginning. Only the best fused silica tubing is chosen. The inner diameter has an extremely narrow tolerance.
Then the capillaries are subjected to hydrothermal treatment. This is to ensure that the surface has a high and uniform density of silanol groups, which is critical for the subsequent manufacturing steps. In the second step the surface is deactivated. The third step involves bonding and crosslinking. HAMILTON uses extremely pure polymers for its phases in order to ensure efficiency, reproducibility, stability and minimal bleed. The olymers are carefully fractionated so as to eliminate low molecular weight
