Reagents for the determination of silica in water samples.

Supplier: Agilent

Pre-aligned fused-silica capillaries from Agilent Technologies are designed and optimised for ease of use and reliability. All capillary ends are cut to a smooth, mirror-like finish. In addition, the polyimide outer coating is removed from the ends. These processes ensure minimal sample adsorption and help maintain sharp peak shapes. All capillaries have a pre-made detection 'window' and a built-in alignment stopper that allows rapid and precise insertion in the alignment interface.
