   Författare :Torbjörn Lindblom; Bengt Nygård; Sten-Eric Lindquist; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Nitro-cellulose; NC; Propellant; Stabilizer; Diphenylamine; DPA; Stability; Shelf-life; Chemometry; FTIR; HPLC; Microcalorimetry; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : The methods HPLC, microcalorimetry and FTIR together with chemometry, provide good analytical tools to follow the degradation of nitro-cellulose.The degradation products formed from diphenylamine (DPA) during storage can be followed with HPLC. FTIR, together with chemometry, also gives the precision needed for safety control of propellants. LÄS MER
