Looking for a straightforward way to analyze polyamides and nylon? This video demonstrates how to use 99.50% purity Hexafluoroisopropanol (HFIP, CAS 920-66-1) as a high-performance solvent. We walk through its role in dissolving polyamides and esters, show why adding sodium trifluoroacetate reduces sample aggregation, and explain the need for 40°C conditions to manage column back pressure. You'll also see how a specialized PL HFIPgel column handles HFIP's high polarity for reliable GPC/SEC results. A practical, no-nonsense guide for lab and B2B professionals.
