The Waters Alliance 2695 HPLC Separation Module is a high-performance liquid chromatographic system with a quaternary, low-pressure mixing pump and inline vacuum degassing. It is designed for in-vitro diagnostic testing to analyze a variety of compounds. The Waters 2695 HPLC System features quaternary blending with a fixed delay volume for consistent results, regardless of the systems back pressure.  Waters 2414 Refractive Index Detector is well-suited to analyze compounds that are without strong UV chromophores, fluorophores, or electrochemical or ionic activity. RI detectors are used to analyze carbohydrates and lipids and in polymer analyses by gel-permeation or size-exclusion chromatography. It measures changes in the bulk properties of the solvent and the solutes under investigation, exploiting the improbability that solvents and solutes would share the identical refractive index.
