Introduction

Standardized Interpretation of Solid Phase Extraction-Gas Chromatography

Standard Dimensions	Features of Method 1	Features of Method 2
Scope of Application	Middle distillates without fatty acid methyl esters	Diesel with a volume fraction of fatty acid methyl esters less than 10%
Separation components	Aromatic components and non-aromatic components	Aromatic components, non-aromatic components and fatty acid methyl ester components
Detection accuracy	±0.3% (repeatability)	±0.1% (repeatability)

Technical Background and Application Cases

Standard Formulation Background:With the increasing demand for the detection of aromatic components in petroleum products, traditional separation methods are difficult to meet the requirements of high precision and high efficiency. Solid phase extraction-gas chromatography combines the selectivity of solid phase extraction and the sensitivity of gas chromatography, becoming an ideal solution to this problem.

Implementation Suggestions

Instrument Selection:Select a non-polar quartz capillary column that meets the requirements of Table 1 to ensure the separation effect.
Reagent Preparation:Use analytical pure anhydrous ethanol, dichloromethane and other reagents to avoid impurity interference.
Sample Processing:Strictly collect and pre-process samples in accordance with standard requirements to ensure data accuracy.
Quality Control:Regularly use reference samples to verify the performance of the analytical system to ensure long-term stability.
