Agilent 7500ce - Reaction Cell Technology Made Routine
The 7500ce meets the demands of the routine trace metal analytical lab that require high performance from reliable, robust and simple to use instrumentation. The 7500ce offers unmatched detection power in the most challenging sample matrices found in the environmental industry. It is equally suited to the toughest analytical challenges found in the clinical, foods, petrochemical, metals, pharmaceutical, forensic and geological industries. New features include a simple-to-use Octopole Reaction System (ORS) for interference removal in complex sample matrices, allowing the:
direct analysis of key elements in estuarine and open ocean seawater ultratrace measurement of Se and Se isotope ratio analysis in biological sample matrices ultratrace measurement of As, Se and Cr in clinical sample matrices The 7500ce incorporates a new digital-drive RF generator that supplies the ICP RF power. This generator improves coupling efficiency resulting in a higher temperature and more stable plasma for more reproducible analyses. The sample introduction system comprises a quartz torch and a quartz double-pass spray chamber fitted with a highly efficient and precise MicroMist concentric nebulizer for excellent sensitivity and stability. The 7500ce’s completely new ion optic is optimized for analyzing high matrix samples.
As a result of these technological enhancements, analytes can be measured at trace levels even in matrices with high levels of dissolved solids (100’s-1000’s mg/L of Na, K, Ca, Mg, and Cl). In addition, the ion optic can be removed easily and replaced with the ion optic system used in the 7500cs, without the need to vent the vacuum system. This gives users added flexibility and capability to analyze all sample-types.
Plasma and cell gasses are controlled by a new, Agilent-designed Active Mass Flow Control system, and ICP RF power is supplied by Agilent’s new digital-drive RF generator offering higher coupling efficiency. The new ICP-MS is also ready-configured to meet strict worldwide regulatory requirements including US EPA methods.
Features
- ORS technology for interference removal
- On-axis reaction cell for increased sensitivity demanded by research/speciation applications
- Elimination of polyatomic interferences on critical elements such as arsenic, selenium, chromium, vanadium and iron using simple gases helium and hydrogen
- Interference removal without matrix matching, element-specific optimization or interference equations
- High transmission ion lens (off-axis ion lens) – for increased sensitivity and matrix tolerance
- Easy to set up and use for routine trace analysis of complex, often unknown sample matrices – retaining the full capability of ICP-MS as a multi-element measurement technique
- Dynamic range from low-ppt for mercury, arsenic and selenium to 1000s of ppm for sodium in the same analytical run, thereby eliminating the need for additional analytical techniques, such as ICP-OES, GFAAS, and cold vapor.
- Standard mode (no cell gas) also available for complete flexibility in operation
- Sample introduction system optimized for high matrix applications
The 7500ce brings reaction cell technology into the routine world - it is just as easy to use and set up as conventional quadrupole ICP-MS, but with the ruggedness needed to handle long term exposure to very high matrix samples.
