Features of ICP-MS DW-SUPEC7000 Inductively Coupled Plasma Mass Spectrometer

1. Ion source

  • Balanced drive, reduces ion kinetic energy dispersion, reducing secondary ion production, without additional expensive consumables such as shielding ring, can eliminate the secondary arc discharge of the cone mouth, prolong the service life of the cone.
  • Provide 500W ultra-low power standby, reduce the argon consumption by more than 50%, and the argon consumption is only 5 L/min.

2. Interface: nickel and platinum. Handle type cone changing system, with interlock protection, to prevent abnormal operation. Simple external cone maintenance, without vacuum leakage can be convenient cone maintenance, and avoid coil damage.(10 sets of cones shall be provided for cone replacement)

3. Extraction lens: The extraction lens can use zero voltage, negative voltage and positive voltage and other extraction modes, unique design, maintenance-free cleaning.

4. Ion transmission system: low background ion transmission design, ion before and after two off-axis, to achieve the effective elimination of interference particles (neutral particles, electrons, photons), without the need to replace the cleaning ion lens.

5. Collision reaction cell: With a new six-pole collision / reaction cell system, the distributed intake system eliminates maximum interference, greatly improves collision efficiency and improves sensitivity.

6. Four level bar mass analyzer: high precision pure Mo material quadrupole, ensure the best mass axis stability, using 2.0 MHz low frequency drive quadrupole, to obtain a wider mass spectrum analysis range and better mass axis stability.

7. Detector: pulse / analog dual-mode discontinuous tap pole detector can complete scanning and selection analysis (qualitative and quantitative analysis) during the first injection process, and can realize automatic switching between analog and pulse modes.

8. Plasma visual system: it has the function of real-time plasma observation with electromagnetic shielding. It can monitor the plasma state in real time through the workstation software, and monitor the state of plasma, cone mouth and central tube in real time to facilitate sample analysis, maintenance and confirmation.
