Webpheophytin. In environments with high chlorophyll b concentrations, we strongly recommend using the Welschmeyer (non-acidification) method. High concentrations of chlorophyll c can result in a slight overestimation of chlorophyll a and an underestimation of pheophytin a sometimes even resulting in negative pheophytin readings. WebPheophytin, a natural degradation product of chlorophyll, has an absorption peak in the same spectral region as chlorophyll a. It may be necessary to make a correction when pheophytin concentration becomes significantly high. "Corrected" chlorophyll a refers to the method with the pheophytin correction.
