In this article, we depicted the structure of the investigated fat-and water-soluble vitamins in Fig. 2. Unfortunately, the published structure in Fig. 2 was vitamin K3 (Menadione) instead of vitamin K1 (Phytomenadione) (log P = 9.7, calculated with Marvin Sketch) which was actually used in the presented experiments.

Additionally, we want to clarify the final buffer concentration of the 1D gradient method which was 15 mM ammonium acetate (pH adjusted to 4.5) as correctly stated in the respective Figure captions and the 2D conditions used for the separations depicted in Fig. 10 (conditions as described in the Materials and Methods part are correct): Mobile phases: A: H2O, 0.1% FA, B: ACN, 0.1% FA, isocratic separation at 80% B after direct transfer, focusing (5% B), and focusing (5% B) with ASM, respectively. The corresponding text is still correct.
