The application of CID(+) to the polyglycol amines in the APCI-FIA-MS-MS(+) mode showed a product ion pattern with ions equally spaced with A m/z 44 starting at m/z 212 as shown in Fig. 2.5.6(c). In addition, the inset also contains the fragmentation scheme of the fatty acid polyglycol amine parent ion at m/z 670.

FIA-APCI-MS-MS(+) (CID) product ion mass spectrum of cationic surfactant compound (m/z 538) fatty acid polyglycol amine type observed in the Saale river, Germany (general formula R—N H((CH2—CH2—OH)x)—(CH2—CH2—OH)y X fragmentation behaviour of [M]+ parent ion at m/z 538 under CID conditions is presented...

AEOs spiked into raw wastewaters were applied to elaborate an APCI or ESI-LC-MS method to determine non-ionic surfactants after SPE. Ionisation efficiencies of both interface types were compared and the more effective APCI technique then was applied for quantification [334]. Recoveries observed with standard determination methods for surfactants and MS detection techniques for different types of surfactants (e.g. alkylether carboxylates, sulfosuccinates, fatty acid polyglycol amines, quaternary carboxoalkyl ammonium compounds, modified AEOs, EO/ PO compounds, APGs, alkyl polyglucamides, betaine and sulfobetaine) in spiked wastewater samples were compared by applying APCI and/or ESI(-i-/-).Poor recoveries were obtained by standard methods but good results by MS [335]. APCI and... 

Nonionic Surfactants. The nonionic surfactants do not dissociate in an aqueous medium. Their solubility is provided by the polar group, such as a polyglycol ether or a polyol. The most important types of fatty nonionic surfactants are the polyglycol ethers of fatty alcohols, fatty acids, amines, and amides.

Fatty acid amines and fatty amines can also be ethoxylated in the same way. The fatty acid amide polyglycol ethers or fatty amine polyglycol ethers thus obtained are very gentle for the skin and are therefore also used in cosmetics, in the textile industry and in special detergents [27, 28].
