Coating Analysis Gas Chromatography Analysis Solution

Coating Analysis Gas ChromatographInstrumentation:

The gas chromatograph includes the following configurations:

A split injection port with replaceable vaporization chamber liner,

Programmed temperature controller

Detector, hydrogen flame ionization detector

Chromatographic column, using a polydimethylsiloxane capillary column method with a 6% cyanopropylphenyl/94% dimethylpolysiloxane coated capillary column (RTX-1301) as the primary column

Injector, microsyringe, 10 microliters

Sample vials, approximately 20 mL glass vials with sealable caps

Balance, accuracy 0.1 mg

Internal standard: Diethyl adipate (DEA) serves as both the internal standard and a 250°C boiling point marker, distinguishing between VOC and non-VOC substances present in coating samples.

Reagents: Acetonitrile, diethyl adipate, ethylene glycol, 1,2-propylene glycol, diethylene glycol monobutyl ether, ethylene glycol propyl ether, all of analytical grade; sample, interior wall latex coating

Gas chromatography analysis method has become quite popular in coatings due to its unique performance. As early as 1997, this method was used to test numerous products from companies like Nippon Paint and Huasheng Chemical Factory. It has been successfully applied in the analysis of residual monomers, free monomers, solvents, and VOCs, providing excellent technical assurance for the development of the coatings industry and environmental protection.
