Scope:

ASTM D6843-10 method covers the characterization of silanes of the type bis-(triethoxysilylpropyl) sulfanes by gas chromatography.

Test Procedure:

In this ASTM D6843-10 method, a sample of the silane is analyzed by gas chromatography to determine the amount of additional, volatile components.  The peak areas in the chromatogram data are used for analysis calculation. The amount (in weight %) is calculated based on individual response factors of components.

Specimen size:

A Sample of Bis-(triethoxysilylpropyl) sulfanes in gm.

Data:

Carrier gas He, linear velocity 20 to 50 cm/s
Split ratio: 1:4 to 1:10
Injector temperature: 250°C
Oven temperature: Temperature program: for example,
50°C / 2 min
6.5°C / min
260°C / 15 min
(Injector temperature & Oven temperature parameters programs are adjusted based on appropriate column characteristics.) Combustion gasses H2, air as needed for flame ionization detector.
