Title: Paul E Larson: Innovator in Spectrophotometric and Nephelometric Technologies

Introduction

Paul E Larson is a notable inventor based in Fort Collins, Colorado. He has made significant contributions to the fields of spectrophotometry and nephelometry, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of Larson's latest patents is a "Method for Spectrophotometric Compensation for Colorimetric Reagent." This method addresses the error in the amount of indicator added to a sample during bleaching chemistry analysis. It involves a reagent system that includes an indicator and a dye in specific relative amounts. This ensures that the indicator at one wavelength and the dye at another wavelength exhibit the same absorbance at zero concentration of the parameter of interest. The method compensates for errors by measuring the decrease in absorbance at the measuring wavelength after the indicator reacts with the parameter of interest, compared to the absorbance at the reference wavelength.

Another significant patent is the "Low Turbidity Nephelometer." This improved nephelometer features a transparent cell designed to contain a liquid sample, along with a light source and a detector. The design reduces stray light reaching the detector, enhancing measurement accuracy. The cell is characterized by the illuminating light beam or the detected light passing through the cell wall face at an acute angle to the normal of the cell wall face.
