This article investigates the applicability of HPLC‐UV, ultra performance LC‐evaporative light‐scattering detection (UPLC‐ELSD), HPLC‐ESI(+)‐MS and HPLC‐hybrid linear ion trap (LTQ) Orbitrap MS for the analysis of different non‐ionic antistatic additives, Span 20, Span 60, Span 65, Span 80, Span 85 (sorbitan fatty acid esters), Atmer 129 (glycerol fatty acid ester) and Atmer 163 (ethoxylated alkylamine). Several alkyl chain length or different degrees of esterification of polyol derivatives can be present in commercial mixtures of these polymer additives. Therefore, their identification and quantification is complicated. Qualitative composition of the studied compounds was analysed by MS. HPLC‐UV, UPLC‐ELSD and HPLC‐LTQ Orbitrap MS methods were applied to the quantitative determination of the different Spans, Atmer 129 and Atmer 163, respectively. Quality parameters of these methods were established and no derivatization was necessary.
