LIQUID CHROMATOGRAPHY DETECTOR

摘要

Sapphire is a universally compatible, four-channel liquid chroma-tography detector. Sapphire features a revolutionary sapphire and quartz composite variable path-length flow cell, which allows concurrent measurement of ultraviolet (UV) absorption at 250 and 280 nm, refractive index, and conductivity. Sapphire's innovative design allows an unprecedented 0.001-100 A.U. UV detection range when normalized to a 10 mm path length. Deep UV LED light sources eliminate warm-up associated with traditional lamps and extend lifetime. Data is visualized in real-time on a four color integrated color monitor, and is USB-exportable. Sapphire is designed for purification of proteins and other biological materials as well as for FLASH chromatography.
