Rapid and Reliable Routine Analysis of Urine by Octopole Reaction Cell ICP-MS Application

چکیده
The Agilent 7500c Inductively Coupled Plasma Mass Spectrometer (ICP-MS) was used for the fast, routine, and reliable analysis of 23 trace elements in urine. The complete method validation for all elements is described, including the evaluation of short-term and long-term stability, the analysis of different reference materials and the discussion of precision and accuracy in internal and external quality assurance. The urine samples were analyzed directly after a low dilution of 1/5 (v/v) with 1% (v/v) nitric acid. Using this simple sample preparation method, one operator can prepare more than 100 samples in less than 1 hour. An ICP-MS fitted with an octopolebased collision/reaction cell enables the simultaneous determination of all 23 elements either in the normal concentration range for the essential elements or at concentration levels relevant for occupational and environmental health.

متن کاملBasic Performance of the Agilent 7700s ICP-MS for the Analysis of Semiconductor Samples
Agilent ICP-MS systems have become the benchmark for accurate low-level analysis of trace contaminants across a wide range of high-purity chemicals used in the semiconductor industry. As the first commercial ICP-MS to offer reliable and routine cool plasma operation, the Agilent 4500 Series ICP-MS set the standard for low level analysis of the previously problematic elements Na, K, Ca and Fe. B...
متن کاملUnmatched Removal of Spectral Interferences in ICP-MS Using the Agilent Octopole Reaction System with Helium Collision Mode Application
Many routine laboratories have adopted ICP-MS as their primary technique for metals analysis due to its simple operation as a multi-element analyzer. However, despite its higher performance for the targeted removal of specific interferences, collision/reaction cell (CRC) ICP-MS remains relatively understudied in terms of its multielement capability. This work demonstrates that the Agilent 7500c...
