Figure 4From: Methodological modifications on quantification of phosphatidylethanol in blood from humans abusing alcohol, using high-performance liquid chromatography and evaporative light scattering detectionDose response curves. Dose response curves of the ELSD detector to phosphatidylethanol. The solid line represents the fitted mixed linear-exponential function y = a + bx - a exp(-dx). An expanded view of the low-amount area is given in the inset.Back to article page
