The Metal Analysis laboratory of the CCiTUB has acquired a new inductively coupled plasma mass spectrometer (ICP-MS). The instrument is a Nexion 2000 model from Perkin Elmer, equipped with collision/reaction cell technology. This technique enables the analysis of approximately 70 elements at trace and ultra-trace concentration levels, and it is applicable to a wide variety of samples, although in many cases, a pre-measurement digestion process is required.
This new equipment offers improvements in sensitivity, both in standard and collision modes, data processing capabilities, and reduction of interferences compared to the other two ICP-MS instruments of the same technique already in operation within the laboratory. It is also configured to work in reaction mode using oxygen to enhance the measurement of certain elements.
The equipment is already operational in the laboratories of the Metals Analysis laboratory and complements the existing atomic spectroscopy instrumentation (ICP-OES, XRF, and DMA).
