Abstract
Overview
ISO 11215:1998 specifies a validated gas chromatographic (GC) method for measuring adipic acid in modified starch products - specifically acetylated di‑starch adipates. The standard covers determination of total adipic content and free adipic acid using extraction, silylation and capillary‑column GC with an internal standard. Annexes provide typical chromatographic conditions, a sample chromatogram and interlaboratory precision data.
