A low cost pc-based voltammetric analyzer for determination of cadmium, copper, lead, nickel, zinc and other trace elements in water
(Lima, 2002-06)
Anodic-stripping voltammetry, like as other electro-analytical techniques of chemical analysis can be very valuable as complements for neutron activation analysis (NAA), for rapid, accurate and simultaneous determination ...
Application of the Allen–Oxley iterative method of phase retrieval to series of images obtained by focus variation
(Lima (Perú), 2008-11)
The application of the iterative method of phase retrieval to series of images obtained at different defocus values is described and discussed. It is shown that the iterative scheme is robust in the presence of discontinuities ...
Quality assurance of analytical results in environmental samples by means of participation in intercomparison round
(Lima, 2003-07)
In developing countries, limited resources in the laboratories hinder quality assurance. One way to overcome this problem is to participate in international interlaboratory comparison rounds in order to asses the reliability ...
Ceramics from Villa El Salvador, a late formative site from the Central Coast of Perú
(Lima (Perú), 2007-08)
We applied a multielemental analytical method for characterization of archaeological ceramics from Villa El Salvador. The ceramics were characterize using Instrumental Neutron Activation Analyses (INAA), Energy-Dispersive ...
