Effect of different solvent compositions for acylcarnitine analysis in serum and in blood; 80 % methanol with 0.1 % formic acid (blue, circles), 80 % acetonitrile with 0.1 % formic acid (red, squares), and 80 % acetonitrile (green, triangles) were tested for a serum and b blood samples. The effect of organic solvent percentage for acylcarnitine analysis was further investigated, by varying the percentage of methanol from 60 to 100 % with 0.1 % formic acid for serum sample (c), while the percentage of acetonitrile was varied from 60 to 100 % without adding acid for the blood sample (d)
