Abstract
A method for determining a physical property related to a charge of a constituent of a sample, from field flow fractionation measurements with an additional electrical field, comprising the steps of obtaining a first fractogram of a first sample and a second fractogram of a second sample, wherein the first sample and the second sample are samples of a same substance, the first fractogram has been generated using a first electrical field, the second fractogram has been generated using a second electrical field, and a strength of the first electrical field and a strength of the second electrical field are different from each other; determining, by using a first mapping, from a first intensity value of the first fractogram, a first value and determining, by using a second mapping, from a second intensity value of the second fractogram, a second value; and determining, based on the first value and the second value, a physical property related to a charge of a constituent of at least one of the first sample and the second sample; wherein the first mapping maps the first intensity value to the first value of a first bijective function over time and the second mapping maps the second inte…
