Abstract:To establish a method for the determination of residual solvents in cross-linked sodium hyaluronate gel with head-space capillary gas chromatography(CGC),a SE-30 capillary column(50 m×0.53 mm×3.0 μm)and hydrogen flame ionization detector(FID)were applied. The detector temperature was 250℃ and the injector temperature was 180℃. The column temperature was maintained at 50℃ for 2 min,then raised at a rate of 10℃/ min to 160℃ and maintained for 5 min. The sample was dissolved in water. The containers of head-space injector were in equilibrium at 80℃ for 30 min,and the splitting-ratio was 1∶1. The measured solvents were separated completely. The calibration curve of each solvent showed a good linear relationship with good precision and accuracy. |
Key words:capillary gas chromatography;cross-linked sodium hyaluronate gel;residual solvents |
