Alkylbenzene
sulfonates (ABS, LABS, LAS) are the quantitative most important tensides for household and industry. Therefore their determination especially in
environmental samples is an important problem. Other tensides relevant to
environment are alkylphenolethoxylates. These nonionic tensides play only a
small part in quantitative relation in comparison to other tensides, but they
posses very unfavorable ecological characteristics. Both families can be
determined by UltraSep ES TENSID simultaneously with the toxic phenols. The
application shows behind of pentachlorophenol the alkylbenzene sulfonates of a
sample of Marlon (HÜLS). The isomeres with C10, C11, C12, and C13 alkyl chains
give one peak each. After them there appear the ethoxylated phenols as a group
peak (C number distribution), fully separated from the phenols they are based
on.
