A Zero order absorption spectra of Blank plasma (….), 4 and 12 µg/mL ASP in methanol (black) and in plasma (red). And 2 and 4 µg/mL ROX in methanol (black) and in plasma (red). B Ratio spectra of 4 and 12 µg/mL ASP in methanol (black) and plasma (red) using ROX 20 µg/mL as divisor. And 2 and 4 µg/mL ROX in methanol (black) and plasma (red) using ASP 36 µg/mL as divisor. C ¹DD of 4 and 12 µg/mL ASP in methanol (black) and plasma (red) using ROX 20 µg/mL and ¹DD of 2 and 4 µg/mL ROX in methanol (black) and plasma (red) using ASP 36 µg/mL as divisor.
