FTIR Spectrometer FTIR Spectrometer . Double Beam: There are two light sources, two cuvettes, and two detectors. SPECTROSCOPY Light interacting with matter as an analytical tool . Single Beam Spectrophotometer Slideshare. A single beam spectrophotometer measures the relative light intensity of the beam before and after a test sample is inserted. Performance And Specifications Of Spectrophotometer . Single beam is used for quantitative analysis, while double beam is used for qualitative analysis. The spectrophotometer is an instrument which measures an amount of light that a sample absorbs. When light passes through a solution, a certain fraction is being absorbed. The light travels in one direction and the test solution and blank are read in the same. The concentration of an analyte in solution can be determined by measuring the absorbance at a single wavelength and applying the Beer-Lambert Law. Single and double beam in struments.

Single-beam UV-Vis spectrophotometers can measure in the wavelength range 190 to 750 nm (although some go up to 1100). The key difference between single beam and double beam spectrophotometer is that in single beam spectrophotometer, all the light waves pass through the sample whereas, in double beam spectrophotometer, the light beam splits into two parts and only one part passes through the sample.Spectrophotometers are analytical instruments used to quantify the analytes in a given sample using a light beam. A single beam spectrophotometer measures the relative light intensity of the beam before and after a test sample is inserted. Optical Instruments Single beam. SINGLE BEAM SPECTROPHOTOMETER. Single channel sensors will, at best, refer their internal energy signal transmission towards a reference point external to the sensor itself, like a known calibration gas mixture or the natural fresh air baseline.
