Im. Maksimova et al., CONTINUOUS-FLOW ANALYSIS - A CAPILLARY COLUMN WITH HYDROPHOBIC INNER SURFACE FOR THE SIMULTANEOUS DETERMINATION OF CALCIUM AND MAGNESIUM, Mendeleev communications, (4), 1995, pp. 146-147
A capillary tube with a hydrophobic inner surface, which was non-coval
ently coated on-fine with quinalizarin, has been used for the simultan
