Latest Patents

Masao Hashimoto holds a patent for an atomic absorption spectrophotometer. This invention describes an absorption profile that indicates a relationship in atomic absorption spectroscopy between the absorbance of a desired element and time. The key feature of this invention is that the half-width of the absorption profile remains constant, regardless of the concentration of the desired element in a sample. This allows for the half-width of the absorption profile to be determined in advance from data obtained by measuring a standard sample. The spectrophotometer calculates the true peak value of an absorption profile by using the time width of the profile at a predetermined absorbance and the previously determined half-width.
