SummaryA method has been developed for the estimation of iron, copper, zinc, calcium and magnesium in human platelets using atomic absorption spectrophotometry. Fe and Cu are either absent or present in very low concentration approaching the limit of detection: Zn, Ca and Mg are readily detectable. EDTA is preferable to ACD(A) or heparin as the anticoagulant for collection in that the platelet yield is reliable: however, slightly low results for Ca and Mg are obtained. Corrections for residual plasma and contaminating red cells are essential. Plasma and platelet metal levels in 33 normal subjects are reported together with the findings in four studies undertaken on platelets obtained from subjects with polycythemia vera.

Glycine Synthesis

The article describes the reactions of glycine synthesis with alkaline, alkaline-earth and divalent 3-d metals, which were carried out during the experiment. Hydroxides or sulfates of lithium, magnesium, calcium, manganese, iron, copper, zinc, cobalt and sodium were used as reagents for the synthesis. The physicochemical properties of the obtained compounds were studied. Keywords: chelates, glycinates of alkaline and alkaline earth metals, glycinates of divalent 3-d metals.

Good Agreement

The method of total reflection fluorescence analysis was used to obtain concentrations of iron, copper, zinc, and bromine in human sera. It was first applied to the commercial control-serum preparation known as Seronorm, and the results obtained were in good agreement with quoted values. The method was then used to determine the concentrations of iron, copper, zinc, and bromine in a random sampling of 62 individuals in an essentially Chinese population. The results are discussed. We feel that this is a suitable method for trace-element analysis of blood in an average laboratory. It is rapid, simple, and economical, besides being multielemental and nondestructive and requiring very small quantities—which seems to be a must in pediatrics.

ICP-AES was used for the simultaneous multiple element detection of trace metals species separated by high-pressure liquid chromatography (HPLC). The technique is demonstrated for the determination of nitrilotriacetic acid (NTA) and ethylenedia-minetetraacetic acid (EDTA) chelates of copper, zinc, calcium, and magnesium. Multi-element chromatograms were obtained using a 32-channel polychromator programmed to perform a series of time-resolved intensity integrations. Data were retrieved channel-by-channel and plotted in histographic form. Comparison with UV absorbance and single-channel ICP-AES tracings reveals that the histograms reflect reliable chromatographic data. Linearity and precision of the system were found to be good in the 20 to 2000 ng range.
