YSI ColorimetersA new line of single and multiparameter colorimeters March 14, 2013 Presented by Laura St. Pierre
What is a Colorimeter?A Colorimeter measures light absorbance at a particularwavelength. gThe term photometer and colorimeter are often inter-changed. gThe term ‘photometer’ includes instruments that canmeasure scattered light intensity, absorbance orfluorescence.A spectrophotometer measures light absorbance acrossmultiple wavelengths per measurement.
How does a colorimeter work? Beer’s Law Simply stated: There is a logarithmic relationship between the light g p g absorbed when passed through a colored medium to the amount of colored substance in the light’s path and the length of that path.
How does a colorimeter work? The amount of light passed through a colored medium can be expressed as either Absorbance or as % Transmittance YSI uses absorbance but provides a direct readout measurement.
How does a colorimeter work? Summary Light passes through a reacted sample and is absorbed in amounts proportional to the p p concentration of the analyte you are testing. The colorimeter measures the absorbance and displays it as a concentration.
