چکیده
In Microsample X-ray Analysis (MXA), a droplet of sample-typically 50 microliters-is evaporated onto a thin film sample support substrate and the resulting residue is analyzed for trace elements. In this work we present the development of an automated robotic sample deposition system designed with the goals of improving the uncertainty in residue formation while reducing the drying time to improve laboratory response time. Before implementation on the automated robot, the drying parameters of droplet size, drying method (hotplate or dry flowing nitrogen), drying temperature, and time were explored.

PREPARATION AND CHARACTERIZATION OF DRIED-RESIDUE CALIBRATION STANDARDS FOR USE IN MICROSAMPLE X-RAY ANALYSIS (MXA), E.C. Anderson, B. Shumway and D.C. Turner, pp. 456-464
Microsample X-ray Analysis (MXA) is one of the most sensitive XRI? methods using conventional energy-dispersive or wavelength-dispersive spectrometers. Detection limits in the parts-per-billion are being routinely achieved using standard laboratory instruments with only minor modifications, In the technique, a droplet of sample-typically 50 microliters-is evaporated onto a thin film substrate a...
متن کامل[Co(NH3)5(NO3)](NO3)2 as an energetic coordination precursor for the preparation of Co3O4 nanoparticles at low temperature
In this paper, an energetic coordination compound namely pentamminenitratocobalt(III) nitrate, [Co(NH3)5(NO3)](NO3)2, was used as a new precursor for the preparation of Co3O4 nanoparticles. The results showed that the complex is easily decomposed into the Co3O4 nanoparticles at low temperature (200 °C) without employing a surfactant or solvent and any complicated equipment. The product was char...
