“…The authors also noted some positive effects of presence of surfactants in PCR mixture such as improvement with baseline drift and decrease of background noise of PCR. Usually the additive of 0.5 -2.0% w/v of nonionic surfactant Triton X-100 was used for the solubilization of such organic reagents as Dithizone derivatives [68,69], CAS [34], and 5-Br-PADAP [70] in PCR.…”

Review Recent developments in the high-performance chelation ion chromatography of trace metalsThere have been a number of significant developments in the high-performance chelation ion chromatography (HPCIC) of trace metals in recent years. This review focuses on these developments, while giving important information on the fundamental parameters controlling the chelation sorption mechanism, including type of chelating group, stability constants, kinetics, and column temperature. The discussion pays particular attention to the types and properties of efficient chelating stationary phases which have been fabricated for certain groups of metals. The review also describes a number of major improvements in postcolumn reaction detection including the use of the latest reagents and noise reduction strategies to improve sensitivity and reduce LOD. In the final section, an indication of the applicability of HPCIC to a range of complex sample types is given with some key examples and chromatograms using the latest high-efficiency chelating phases.
