base-line technique
base-line technique [ANALY CHEM] A method for measurement of absorption peaks for
quantitative analysis of chemical compounds in which a base line is drawn tangent
to the spectrum background; the distance from the base line to the absorption peak
is the absorbence due to the sample under study. { ba¯s lı¯n tek ne¯k }
