ABSTRACT
OBJECTIVE:
To establish a methodology for the detection of cyclohexanone in workplace air by capillary column gas chromatography.METHODS:
The air sample in the workplace was collected with activated carbon tube and desorbed with carbon disulfide.The extracts were separated by FFAP capillary column and detected with flame ionization detector,and quantified using standard curve.RESULTS:
The linearity range of cyclohexanone was 10.00-1 000.00 mg/L,and the correlation coefficient was 0.999 9.The detection limit and the lower limit of quantification were 1.31 and 4.37 mg/L,respectively.The minimum detectable concentration and the minimum quantitative mass concentration were 4.37 and13.11 mg/m~3,respectively.The average desorption efficiency of cyclohexanone was 95.80%-97.88%.The within-run and between-run relative standard deviation were 0.52%-3.12% and 3.28%-4.75% respectively.The samples could be stored at room temperature for 7 days.CONCLUSION:
This method is simple and accurate.It is suitable for the determination of a large number of samples.
