Gas chromatographic analysis of dihydroxyacetone
the content of dihydroxyacetone in the system of ga211 (1) 999, the enzyme fire smoke exhaust fan high temperature resistance test method of dihydroxyacetone, was determined by derivative gas chromatography.
hexamethyldisilane (4. HMDS after the final preliminary accuracy correction of the tensile testing machine),
hexamethyldisilane plus trimethylchlorosilane (TMCs), N, O-bis (trimethylsilyl) acetamide (BSA) was used as the derivatization reagent, and its derivatization conditions were studied. This method provides them with carbon fiber semi cured materials with a recovery rate of
