b) The specifications for the water used have been changed (see 7.3, 6.3 in the.2010 edition);
c) The 10mL volumetric flask has been removed (see 7.3 in the.2010 edition);
d) The instrument "pipette" was changed to "pipette" and its capacity was changed (see 8.4, 7.4 in the.2010 version);
e) The pore size of the filter membrane used was changed (see 8.5, 7.5 in the.2010 edition);
f) Columns of the specified brand were removed (see 8.1 in the.2010 edition);
g) The mobile phase composition was changed (see 9.2, 8.2 in the.2010 edition);
h) The detection wavelength was changed (see 9.5, 8.5 in the.2010 edition);
i) Added relevant content on chromatograms (see 9.6);
j) The sample solution preparation method and the specifications for the filter membrane used before entering the column have been changed (see 10.1, 9.1 in the.2010 edition).
