Acclaim Surfactant

P) content. ICP method will not be addressed here. The potential use of a Corona detector to determine base 4 that is not detected by the UV detector will be discussed. The quantitation of the Cl bases is based on one single predominant peak for each base. We have used an Agilent Model 1200 HPLC instrument and an Acclaim surfactant column (5 pm, 4.6 x 150 mm) to evaluate the method. Typical retention times observed for Cl based on UV detection are 2.4 minutes for base 1, 17.1 minutes for base 2, and 15.2 minutes for base 3. A typical chromatogram is presented in Figure 1. The small peak that tails the predominant peak at 2.43 minutes was included in the calculation of the peak area for base 1.

CAD). In contrast to Hypersil 5 MOS, the elution order of the ethoxylated ether sulfates seems to be reversed on Acclaim Surfactant Plus, that is, retention increases with decreasing degree of ethoxylation.
