and troubleshooting the Waters 2414 Reflective Index Detector. It also includes appendices for safety warnings and specifications. Intended use of the Waters 2414 Refractive Index Detector The 2414 Refractive Index (RI) Detector is designed for high-performance liquid chromatography (HPLC) applications. It provides sensitivity, stability, Each of these detectors has its advantages and disadvantages. This instalment of Tips & Tricks compares the RI to other concentration detectors and provides practical tips when using it. How Does an RI Detector Work? In general, RI detectors respond to a change of the refractive index, n. Most detectors are differential refractometers.not only from the detector (specification) but also can be attributed to other system influences such as electronic considerations and smoothness of flow. Signal is defined as the response of a detector to a given concentration of a compound in the detector cell. With differential refractive index detectors, the response is dependent on the2414示差折光(ri)检测器专为科学家实现高灵敏度、稳定性和重现性而设计，是对uv吸收有限或无uv吸收的组分（例如醇类、糖、糖类、脂肪酸和聚合物）进行分析和定量的理想解决方案。
The R-400 differential refractometer measures the deflection of a light beam due to the difference in refractive index between the sample and reference liquids in a single-compact sample cell. The refractive-index detector detects all substances that have a significantly different refractive index from that of the mobile phase. The first instrument incorporating the concept of differential light scattering with component detectors at several angles was a device [34] built and tested for the Food and Drug Administration in 1976 to detect antibiotic residues in meat products. David T. Phillips, who directed much of the instrumentation developed for this project .This detector is a differential refractometer that measures the deflection of a light beam due to the difference in refractive index between the liquids in the sample and reference cells of a single flow cell. A beam of light from the lamp passes through a flow cell which is separated diagonally into sample and reference cells.
