Abstract
The invention provides a method of analyzing a liquid sample, comprising the steps of: passing near-infrared light through the sample, wherein the light travels in metal nanoparticles-added microfiber that is immersed in the sample; obtaining spectral information across a wavelength range of about 750 nm to about 1800 nm; and qualitatively identifying, and optionally quantitatively characterizing, one or more analytes in the sample. Near-infrared spectrophotometer carry out the method is also provided by the invention.
Claims8
A method of analyzing a liquid sample, comprising:
- passing near-infrared light through the sample applied onto a polytetrafluoroethylene (PTFE) surface, wherein the light travels in a microfiber, to which metal nanoparticles have been added, wherein the microfiber has a tapered section, which is immersed in the sample;
- obtaining spectral information across a wavelength range of about 750 nm to about 1800 nm;
- and
- qualitatively identifying, and quantitatively characterizing, one or more analytes in the sample.
A near-infrared spectrophotometer comprising:
- a light source generating near-infrared light to be guided through optic microfiber having metal nanoparticles-added section, wherein said section of the microfiber has a tapered configuration, a sample holder comprising a polytetrafluoroethylene (PTFE) surface for providing an interface between a sample and said metal nanoparticles-added tapered section of microfiber and analysis unit producing the spectral information.
