Introduction

1. Overview of standard method

This standard specifies the method for determining chlorine and silicon in gasoline by inductively coupled plasma optical emission spectrometry (ICP-OES). This method is applicable to the determination of total chlorine and total silicon content in automotive gasoline, M15 automotive methanol gasoline, M30 automotive methanol gasoline and E10 automotive ethanol gasoline.

2. Comparison of standard frameworks

Standard name	Scope of application	Determination elements	Method requirements
ICP-OES method	Automotive gasoline and its blends	Chlorine and silicon	Precisely control instrument parameters to ensure that spectral interference is minimized
GB/T1 7 4 7 6	Determination of elements in lubricating oil additives	Multiple metal elements	Applicable to internal standard method to correct viscosity influence
AS TM D 4 8 0 6	Denatured fuel ethanol	Cl2 element limit requirements	The volatile form of the sample needs to be considered

3. Technical background and evolution analysis

ICP-OES technology, as a highly sensitive elemental analysis method, has been increasingly used in the petrochemical industry in recent years. This standard is based on the characteristics of Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES), combined with the actual detection needs of chlorine and silicon in gasoline, to develop a complete set of determination solutions.

Compared with traditional atomic absorption spectrometry, ICP-OES technology has the following advantages:

Simultaneous detection capability of multiple elements
High sensitivity and low detection limit
Suitable for analysis of complex matrix samples

4. Implementation recommendations

Case study: Standard implementation in a petrochemical laboratory

In actual operation, the following recommendations are made:

Instrument calibration: Regularly calibrate the wavelength and sensitivity of the ICP-OES instrument to ensure accurate analysis results.
Internal standard selection: Oil-soluble yttrium, cobalt or scandium is preferred as the internal standard element to reduce the influence of sample introduction effect.
Sample processing: Strictly dilute the gasoline sample in a ratio of 1:4 to avoid instrument overload due to excessive concentration.
Interference factor control: For high viscosity samples, it is recommended to use matrix matching method or internal standard method for calibration.
