Estimation of Ion Competition via Correlated Responsivity Offset in Linear Ion Trap Mass Spectrometry Analysis: Theory and Practical Use in the Analysis of Cyanobacterial Hepatotoxin Microcystin-LR in Extracts of Food Additives

Figure 2

Linear and exponential fittings of concentration-response dependence for the peak area of the pure MCYST-LR molecular ion of m/z 995 [M + H]+. The red stars indicate the peak areas evaluated by automatic analysis from raw measurements, the blue dashed line indicates the linear function fitting, and the green solid line indicates the exponential fitting function.
