Capillary for analytical chemistry transparent to ultraviolet light

[0026] In general, the preferred embodiment, depicted in FIG. 1, is a fused silica capillary presenting a bore 10 diameter in the range of approximately 1 μm to approximately 500 μm, a glass wall 20 with a thickness ranging from approximately 25 μm up to approximately 500 μm that is coated with approximately 10 μm to 50 μm of plastic cladding polymer 30 that is polymerized from solutions comprised of the of the following formulations: [0027] (a) monomer A, 10-80% by weight, or preferably 30-60% by weight: [0028] (b) monomer B, 0-70% by weight, or preferably 30-60% by weight; [0029] (c) methyl methacrylate, 0-90% by weight, or preferably 40-70% by weight [0030] (d) a free radical initiator, 1.0-3.0% by weight, preferably 1.5-2.0% by weight; [0031] (e) an adhesion promoter, 0-3.0% by weight, preferably 0.5-2.0% by weight; and [0032] (f) an antioxidant, 0-3.0% by weight, preferably 0.025-0.05% by weight.
