Introduction
In-depth interpretation of GB/T 37160—2019 National Standard of the People's Republic of China
This standard specifies the determination of aluminum, calcium, iron, potassium, magnesium, manganese, molybdenum, sodium, nickel, lead, vanadium and zinc in heavy distillates, residual oil and crude oil by inductively coupled plasma optical emission spectroscopy (ICP-OES). It is suitable for the determination of trace metals in heavy distillates, residual oil and crude oil, and provides important parameters for the later processing and production of oil products.

Explanation of professional terms and practical application cases
Inductively coupled plasma optical emission spectrometry (ICP-OES): a technology that uses high-temperature plasma to excite elements in a sample to emit a spectrum of a specific wavelength. Suitable for quantitative analysis of trace metal elements.
Internal standard element: a standard solution added during the analysis process to correct instrument drift and sample matrix effects to ensure the accuracy of the measurement results.
Analysis of standard formulation background and technological evolution
With the growth of global demand for petroleum resources and the improvement of environmental protection requirements, accurate determination of the content of metal elements in oil products has become a key link in production and processing technology optimization and product quality control. Traditional methods have limitations in detection sensitivity and simultaneous determination of multiple elements. ICP-OES has become the preferred technology due to its advantages of high sensitivity and simultaneous detection of multiple elements.
