Microextraction and its application for petroleum and crude oil samples

Area of Science:

• Petroleum Chemistry
• Analytical Chemistry
• Separation Science

Background:

• Petroleum is a complex mixture of aliphatic, aromatic, and heteroatom-containing compounds.
• American Society for Testing and Materials (ASTM) methods are standard for petroleum analysis but require extensive sample preparation.
• There is a need for rapid, automated, and simpler sample preparation techniques in petrochemical analysis.

Purpose of the Study:

• To review microextraction techniques as a complementary approach to existing petroleum sample preparation methods.
• To discuss solvent- and sorbent-based microextraction for petroleum, crude oil, and petrochemical industry samples.

Main Methods:

• Literature review of microextraction techniques applied to petroleum and petrochemical samples.
• Focus on solvent-based microextraction.
• Focus on sorbent-based microextraction.

Main Results:

• Microextraction techniques demonstrate significant potential for simplifying and accelerating petroleum sample preparation.
• These methods can effectively handle the heterogeneity of petroleum and crude oil matrices.
• Microextraction offers a viable alternative or complement to conventional ASTM procedures.

Conclusions:

• Microextraction is an excellent complement to current petroleum analysis methods.
• Solvent and sorbent-based microextraction techniques are suitable for petroleum and petrochemical industry samples.
• Further development in microextraction can lead to more efficient and automated analytical workflows.
