Abstract: The determination method for 14 kinds of metal elements in pipeline transportation crude oil was established using crucible and ICP-AES. The test results show that quartz crucible is a good choice for ashing crude oil and the suitable ashing conditions for pipeline transportation crude oil are 550 ℃，3hr. And a variety of elements can be detected accurately at the same time with sampling once. The element detection limit of the method is between 0.0006-0.7230 mg/L, RSD <7.0% (except cadmium 28.75%), and the standard recovery rate of 91%-115%.
