Stability of CS disaccharides during 4 °C storage in various solvent mixtures. Intensities of individual disaccharides are represented, relative to the control sample. a 90:10 v/v ACN:water; b 75:25 v/v ACN:water; c 10 mM ammonium formate (pH 4.4) in 75:25 v/v ACN:water; d 50:50 v/v ACN:water; e 75:25 v/v MeOH:water; f 10 mM ammonium formate (pH 4.4) in 75:25 v/v MeOH:water)
