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.

9. Silent cover: Silent cover can be configured to reduce laboratory noise and improve the laboratory analysis environment.

10. Sample injection system

• Provide a variety of atomizers, including efficient quartz concentric atomizer with high salt resistance and PFA microinjection, with high atomization efficiency and hydrofluoric acid injection resistance.
• Small volume inert cyclone atomization chamber, small dead volume, strong corrosion resistance, high aerosol atomization efficiency, low memory effect, standard TEC of refrigeration module, refrigeration temperature <-15℃, improve the continuous working stability of the instrument and organic solvent analysis ability, reduce the oxide yield, improve the stability of the instrument.
• Detachable quartz torch tube with split design, pre-collimated torch tube seat built-in air path connection, easy to operate card into the torch tube design, convenient for daily replacement and maintenance without removing the gas pipe.
• A variety of central tubes are optional, and they are separated from the torch tube. For different applications, the central tubes can be replaced for organic, high salt, high sensitivity and HP acid resistance to facilitate replacement and maintenance.
• High-precision gas mass flowmeter is equipped with standard control of four-way working gas, including atomized gas, auxiliary gas, cooling gas and collision gas. The fifth additional gas can be used as the dilution system.
• Fully automatic on-line gas dilution device can be configured, which can dilute the sample matrix to less than 0.3% before the moment tube, ensure that the interface area and mass spectrum area are not contaminated by high matrix, eliminate the signal inhibition effect caused by high matrix, and have two working modes: preset dilution multiple and manual adjustment of the dilution gas flow. Conventional ICP-MS is resistant to ~0.2% salt tolerance and enables direct determination of> 10% salt content after dilution with argon.
