Abstract: ABSTRACT Non-static light-detector pair based variable Trapezoid like path length continuous system The present invention relates to a system for measuring absorbance and scattering in a sample solution, comprising: a monochromatic light source [100] directing light through the sample; a primary photodetector [101] positioned along the same optical axis to measure transmitted light intensity and calculate absorbance; a secondary scattering detector [102] positioned perpendicular to the optical path to measure scattered light; and a control mechanism [103] for synchronizing the movement and positioning of the light source and detectors. The system utilizes a trapezoidal glass tube [104] designed to allow a variable path length, providing different optical depths for light interaction with the sample. The light source and detectors can be adjusted to vary the path length, ensuring accurate and synchronized measurements. Continuous data collection enables the analysis of the absorbance-path length relationship, detecting nonlinear behaviors. This improves analyte concentration quantification in complex solutions and compensates for sample heterogeneity, ensuring more representative measurements across diverse applications.
