The ratio of deproteinization with MSpak GF-4A (a column for Column switching) and with a corresponding column of other company were compared. Since the ratio of deproteinazation is high, GF-2A can suppress the adsorption of protein to analytical columns or LC/MS as much as possible, and keep the reproducibility of analysis. (GF-2A (2.0 mm I.D. x 10 mm) is a custom-made column of GF-4A.)
