Varian cary 50 software1/27/2024 ![]() ![]() NameĪgilent Technologies Cary UV-Vis Spectrophotometerģ0 × 35 mm, 1200 lines/mm, blaze angle 8.6° at 240 nm It has a high-performance R928 photomultiplier tube, tungsten halogen visible source with quartz window, and deuterium arc ultraviolet source (Figure 1). Hardware and Materials The Varian Cary 100 is a double-beam, dual-chopper, monochromator UV-Vis spectrophotometer, centrally controlled by a PC. ![]() The system measures analytes in interstitial water obtained from sediment cores using standard colorimetric methodology. IODP’s Agilent Cary 100 double-beam UV-Vis (ultraviolet–visible) spectrophotometer is ideal for shipboard routine and research laboratory work. Beer’s law, expressed for liquids, can be represented as an equation, where A = absorbance, k = an experimentally determined constant, b = path length, and c = concentration: A = kbc. The principle of Beer’s law is that passing light of a known wavelength through a sample of known thickness and measuring how much of the light is absorbed at that wavelength will provide the concentration of the unknown, provided that the unknown is in a complex that absorbs significantly at the chosen wavelength. ![]() Introduction The principles of spectroscopic analysis rely on Beer’s law.
