| Abstract: | A Chinese cabbage juice concentrate reference material spiked with three kinds of acetanilide herbicides was pre- pared, included acetochlor, butachlor and alachlor. The reference material was blended, packed and then tested on the homogeneity and stability. F test results indicated that the homogeneity was fine and the results of the stability study demonstrated that the reference material was stable after being storaged at - 18 ~C for 180 days. The concentrations of acetanilide herbicides in the reference material were certified and the uncertainties were evaluated. |
| Keywords: | reference material herbicide homogeneity stability uncertainty |
