Foreword
In order to implement the "Environmental Protection Law of the People's Republic of China", reduce emissions of automobile engine pollutants, and supervise motor gasoline.
This standard is established by the addition of detergent.
This standard specifies the basic requirements, performance requirements, test methods, and methods for the rapid determination of the gasoline detergent for the vehicle.
Inspection rules and signs, packaging, transportation and storage.
This standard is formulated by the Science and Technology Standards Department of the Ministry of Environmental Protection.
This standard was first developed.
This standard is mainly drafted by. China Environmental Protection Industry Association, Tianjin Yuetai Petrochemical Technology Co., Ltd., Shenzhen Runhe
Code Industry Co., Ltd.
This standard was approved by the Ministry of Environmental Protection on July 31,.2012.
This standard has been implemented since November 1,.2012.
This standard is explained by the Ministry of Environmental Protection.
Technical requirements for environmental protection products Thin layer chromatography, rapid cleaning agent for motor gasoline
tester
1 Scope of application
This standard specifies the technical requirements for the determination of detergents for motor gasoline and ethanol gasoline by thin layer chromatography.
Inspection methods, inspection rules, marking, packaging, transportation and storage.
This standard applies to the detection of automotive gasoline, ethanol gasoline and methanol gasoline whether a sufficient amount of polyisobutylene and
Polyetheramine (molecular weight 600-1500) is a rapid tester for detergents of effective detergents.
2 Normative references
This standard refers to the terms of the following documents. For undated references, the valid version applies to this standard.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1 Effective substances in gasoline detergents effective substances in gasoline detergent
Among the substances used in gasoline detergents, there are mainly polyisobutylene amines and polyether amines.
3.2 SPE solid phase adsorption column solid phase extraction
A small adsorption column for adsorbing or purifying samples.
3.3 thin layer chromatography
The stationary phase is uniformly applied to the thin plate to form a thin layer of a certain thickness and has a certain separation activity.
Chromatographic separation on a thin layer is called thin layer chromatography.
3.4 ratio shift value Rf value
In thin-layer chromatography, the ratio of the distance from the origin to the center of the spot on the thin plate and the distance from the origin to the front of the solvent.
3.5 reference solution
A polyetheramine or polyisobutylene amine is formulated into a known amoun
