Problems solved by technology

This makes it often difficult to obtain a strict correspondence between the interaction and the material structure by performing titration calorimetry and spectroscopic measurement separately.
So far, there is no instrument at home and abroad that can realize the combined measurement of thermal signals and multiple spectra

Abstract

The invention relates to a heat power measurement device with visible-ultraviolet, fluorescent and Raman spectrum measurement. The measurement device is characterized by comprising a heat measurementsystem, a full-spectrum measurement system and a data acquisition and control system, wherein the heat measurement system is used for measuring titration heat released in a titration process; the full-spectrum measurement system comprises a visible-ultraviolet excitation system, a fluorescent excitation system, a Raman excitation system, a lens system, an optical grating and a multi-channel spectrometer. According to the heat power measurement device provided by the invention, three spectra including visible-ultraviolet, fluorescent and Raman spectra are integrated and optimized with heat measurement; the three spectra share one spectrometer and part of an optical channel, so that a spectrum system is effectively simplified and the cost is reduced.

Description

technical field [0001] The invention relates to a thermal power measurement device, in particular to a thermal power measurement device with visible-ultraviolet, fluorescence and Raman spectrum measurement, involving weak interactions between molecules such as biological macromolecules and molecular self-assembly and other solution reaction systems field of research and application technology. Background technique [0002] Thermal power measuring devices (ie, calorimeters) are widely used in scientific fields such as physics, chemistry, and biology, as well as technical fields such as oil exploration, petrochemicals, and secondary batteries. Among them, the isothermal titration calorimeter is especially suitable for the study of biological systems and weak interactions between molecules. Due to the complexity of this type of system, measurements such as visible-ultraviolet, fluorescence, and Raman spectroscopy are generally supplemented to obtain material structure informat...
