Simultaneous Determination of Six Residual Organic Solvents in Butorphanol Tartrate by Capillary Gas Chromatography with Headspace Sampling
Objective:To develop a headspace gas chromatography method for the residual organic solvents in butorphanol tartrate.Methods: The sample was injected into ZB-1 capillary column by headspace sampler and analysed with FID detector using ethylacetate as the internal standard and H
2
O as the solvent.Results: Methanol
acetone
dichloromethane
ether
chloroform
tetrahydrofuran were linear at the ranges of 1.811~394.6 μg·mL

1.015~389.41
0.130~407.2
0.447~198.3.776~100.6

respectively;The recoveries were 97.2%
98.8%
102.5%
102.3%
100.3%
96.4% respectively.Each of the relative standard deviations was no more than 5.0%.Conclusion: The method is simple
accurate and sensitive with good reproducibility.It can be used for the determination of the residual organic solvents in butorphanol tartrate.
