Determination of essential and toxic metals in blood by ICP-MS using calibration in a synthetic matrix

ثبت نشده
چکیده

A method used to determine Pb in unknown matrices by isotope dilution mass spectrometry (IDMS) was previously published by NIST [1]. IDMS is considered the most accurate method for total blood metals analyses, mainly because it eliminates the blood’s matrix effect [2, 3]. However, the IDMS method is relatively expensive, and cannot be used for mono-isotopic metals such as Mn or As. Alternatively, the use of internal standards (ISTDs) can compensate for matrix effects by correcting the analyte response Determination of essential and toxic metals in blood by ICP-MS using calibration in a synthetic matrix

Trace Element Analysis by ICP-MS and Chemometric Approach in Some Euphorbia Specie: Potencial to become a Biomonitor

In this study, the branch, leaves, flowers, roots and mixed all parts of different nine Euphorbia species were analyzed for their trace element contents by using ICP-MS. The samples were digested by concentrated nitric acid and hydrogen peroxide in a microwave by ICP-MS before the analysis. The accuracy and precision of the method was evaluated by CRM 1573a Tomato Leaves. Trace element contents...

A comparison of clinical laboratory data for assigning a consensus value for manganese in a caprine blood reference material.

Biomonitoring for manganese (Mn) exposure is important due to its potential to cause adverse health effects. In this study, we investigate how different sample preparation methods (simple dilution, digestion, volumetric, gravimetric), calibration protocols (aqueous, blood-based, standard additions), and instrumental techniques affect Mn method bias and analytical imprecision. The techniques use...

Direct determination of 10 trace metals in 50 mL samples of coastal seawater using desolvating micronebulization sector field ICP-MS†

Understanding the trace metal marine geochemistry of temporally variable coastal systems requires intensive sampling programs with attendant analytical burdens. Most established techniques for multi-element trace metal determinations are slow, require a skilled chemist, and are not easily automated. Advances in sample introduction systems and ICP-MS instrumentation now provide marine chemists w...
