Description

An Inductively Coupled Plasma Mass Spectrometer (ICP-MS) measures the elements in a dissolved aqueous sample by spraying an aerosol into a high temperature argon plasma (up to 10,000 degrees Kelvin) and measuring the resulting ions using a quadrupole mass spectrometer. The NexION® 5000 is a multi-quadrupole-based instrument designed to carefully control the ion beam to selectively remove or preferentially measure molecular interferences that form during an IICP-MS analysis.

 

Specifications

Four quadrupoles:
  • First: Quadrupole Ion Deflector (Q0) directs ions to the entrance of the first mass filter 
  • Second: Transmission Analyzer Quadrupole 1 (Q1, full-sized for <0.7 amu mass resolution), acts as a mass filter or as an ion guide to direct ions to the Quadrupole Universal Cell 
  • Third: Quadrupole Universal Cell (Q2), empowered by dynamic bandpass tuning, prevents side reactions with residual reaction gases in the cell 
  • Fourth: Transmission Analyzer Quadrupole 2 (Q3, full-sized for <0.7 amu mass resolution), acts as a mass filter or as an ion guide to direct ions to the detector.

Detector: Discrete Dynode Software: Syngistix for ICP-MS Detection limits (approx.):0.05ug/l, working solution, 2% nitric and/or HCl (limit may vary depends on elements, concentration, matrix etc.)
Instrument settings: 
 
  • ICP RF Power: 1200-1500.00 Watt 
  • Vacuum Pressure: < 8 × 10-6 torr 
  • Pauls stage Voltage: (800-1500) volt 
  • Analog stage Voltage: -(1700-2300) Volt 
  • Plasma gas flow:15-17L/min 
  • Auxiliary gas flow:1-2L/min 
  • Nebulizer Gas Flow: (0.85-1.2) L/min 
  • Lense Voltage: (4-12) volt 
  • Cell Gas: He, NH₃, O₂, CH₄

Applications

The ICP-MS performs a wide range of rapid multi-element quantitative and semi-quantitative analysis of trace, ultra trace, heavy metals of:

  • Water, drinking water, groundwater, wastewater with high organics, seawater, water extracts, acid soluble salts.

  • Plant material, animal tissues, food, compost, manure.
    • Volatiles and solvents - Biological serums (blood, saliva, fluid, buffer matrix - Polymers-plastics for elemental impurities - Charcoals, Graphene, graphite-diamond (acid-MW) extract
    • Sediments, sludges, soils, ceramic, quartz: EPA-3051A (acid-MW) extract 
    • Soil-agricultural applications 
    • Metal and metallurgy: assay, impurities. 
    • Experimental (different solution/ solvent extract)
