| Abstract: | The definition and connotation of the instrument detection limit,method detection limit and sample detection limit were introduced.Base on the determination of kepone in seawater by gas chromatography,several calculations methods were introduced about detection limit and the application.The difference of the calculating results and the rationality of selected parameter were discussed.A suggestion was given about how to use the detection limit to carry out the quality control in analysis laboratory scientifically. |
