Design of a novel field-portable fluorescence spectrophotometer

摘要

The two monochromators of this instrument (excitation monochromator and emission monochromator) have been designed with a specific optical system which has higher transfer energy. All the parts of this instrument have been placed in the inverse plane (33 $MUL 21.5 cm), which makes the instrument compact and installment easy. The design also provides a novel idea to solve the contradiction between system energy and limited power, it only takes a little power to complete most of the fluorescence analyses. An internal microprocessor utilizes chemomtric analysis techniques to determine the concentrations of target analyses in a complex chemical matrix. Typical analysis techniques include multivariate linear regression and principal components analysis.
