The conditions of IP-RP-HPLC-UV-HG -AFS were studied. The conditions of the pretreatment sample, such as types and dosage of proteinases, were investigated. The detection limits (LODs) for six Se species were between 0.77 and 1.77 μg·L1. Then, the proposed method has been successfully ...
This is also a problem when different arsenic species (organic arsenic species such as arsanilic acid, nitarsone and roxarsone) are to be determined in animal meat by HPLC-UV-HG-AFS, which is the basis of this work. In order to improve the detection power, methods of signal treatment ...

Moreover, Hg speciation could also be performed when coupled with HPLC, and the LODs (3蟽) of Hg2+, MeHg and EtHg were 24, 13, and 16 ng L1, respectively, using the HPLC-(UV/nano-ZrO2/HCOOH)-AFS system, with the RSDs better than 4.6% (n= 6)...
