Fig. 4From: Simultaneous quantification of artesunate and mefloquine in fixed-dose combination tablets by multivariate calibration with middle infrared spectroscopy and partial least squares regressionPlots of reference content versus predicted content of artesunate (ARS) and mefloquine (MFQ) determined by multivariate calibration model. Samples of calibration set are represented by black circles and validation set by red down triangles Back to article page
