Fig. 1. The separation of common organic osmolytes using a Waters SugarPak column,
as described in the Materials and methods. (B) Separation of most major
osmolytes common in elasmobranch muscle, as well as several other common
organic osmolytes, using a mobile phase of 500 mg l1
Ca-EDTA. (A) Enlargement of the region of response from the approximate
retention times of 12.5 to 21 min, using different concentrations of Ca-EDTA
as the mobile phase. Note the retention times of glycine and alanine are
reduced as the concentration of Ca-EDTA decreases.
