[Determination of residual epoxyethane in medical instruments by headspace capillary gas chromatography].
OBJECTIVE
To establish a method of determining the residual epoxyethane in medical instruments.


METHODS
An HP-5 capillary column (30 m x 0.32 mm x 0.25 microm), an FID detecter and an oven were used in the determination. The oven temperature was kept at 120 degrees C for 8 minutes, the example inlet temperature was kept at 200 degrees C, while the detecter temperature was kept at 250 degrees C.


RESULTS
The method has a linear range between 5.1920-51.920 microg, (r = 0.997, n = 6). The average rate of recovery of the injecter is 103.3%. The average rate of recovery of the infusion devices is 81.04%.


CONCLUSIONS
The method has been proved to be convenient, sensitive and accurate. It is suitable for the determination of residual organic solvents in medical instruments.
