Working Principle of Inductively Coupled Plasma-Mass Spectrometer (ICP-MS)
To understand the working principle of inductively coupled plasma-mass spectrometer, please see the "Principle of Inductively Coupled Plasma-Mass Spectrometer".
Features of SUP-72 Inductively Coupled Plasma-Mass Spectrometer ( ICP-MS )
The SUP-72 Inductively Coupled Plasma-Mass Spectrometer has fast analysis speed, high sensitivity and excellent interference elimination effect. Specialized design makes the application easier.
Excellent Sensitivity
The aerodynamic simulation design is used at the junction of the high temperature plasma and the high vacuum mass spectrometer inlet, and it is improved from the previous model. The optimized ion interface (optimized double cone structure) enables the SUP-72 ICP-MS to have a higher sensitivity of 350Mcps/ppm or better. Its detection limit as low as sub-ppt is more suitable for analysis of scientific research and third-party testing.
Excellent Ability to Cancel Interference
• The improved collision/reaction cell adopts the waterfall flow distribution air inlet method, so that He is introduced into the cell orthogonally throughout the whole process, forming a good gas distribution. Only 30% of the airflow can achieve the same effect as other collision/reaction cells, greatly improving the efficiency of collision reaction.
• Ion deflection system and high-precision quadrupole mass analyzer effectively eliminate interference factors in detection.
Adaptability to a Variety of Gas Paths
SUP-72 ICP-MS can be expanded to configure seven working gases (including diluent gas, hydrogen, helium, etc.), with better adaptability to meet the analysis needs of various complex and extreme conditions.
Lower Running Costs
The low-power standby mode of the instrument greatly reduces the consumption of argon gas and electricity without turning off the flame, saving costs.
Excellent Performance of Substrate Resistance
Aerodynamically simulated ion interface, high-efficiency ion deflection system, patented collision / reaction cell, self-excited all-solid-state ICP ion source, and argon on-line dilution system (AGOD) ensure that SUP-72 has excellent performance of substrate resistance, 10 % of high-salt samples can be injected directly.

• Based on the direct dissociation technology of high-temperature solid samples in graphite furnace, it is especially suitable for various conventional difficult-to-analyze samples such as insoluble, difficult to digest, organic and soil samples.
• High temperatures up to 3000°C dissociate all samples. Through PID infrared temperature control technology, the temperature control and temperature program function are perfectly realized, which is suitable for the analysis of different elements of different samples.
• Combined with AGOD argon online dilution system, it can effectively eliminate the influence of matrix and improve the analysis precision.
Collision mode + KED to resolve the interference of polyatomic ions
Polyatomic ions from solvents and samples may interfere with test results. The SUP-72 ICP-MS is equipped with a new hexapole collision/reaction cell system and operates in KED mode to eliminate these interferences.
The working principle of kinetic energy discrimination (KED): as shown below. In the collision/reaction cell, initially, the analyte (V) and the polyatomic interfering ions (CL, O) lose the same energy per collision with the He atoms. However, the interfering ions (CL, O) are larger than the test ions (V) and have more collision opportunities. When they reach the exit of the cell, the kinetic energy of the analyte (V) and the interfering ions (CL, O) are no longer the same due to the number of collisions. The interfering ions are blocked by the potential well voltage at the entrance of the latter quadrupole due to the large kinetic energy loss, and cannot enter the latter quadrupole mass analyzer.
After those polyatomic interfering ions are eliminated, the detection limit of ICP-MS is greatly improved.

Description of the Structure of the SUP-72 Inductively Coupled Plasma-Mass Spectrometer
① High-efficiency Sampling System
Detachable Torch Tube
The detachable torch tube is easy to assemble and disassemble. It only needs to replace the central tube to meet the injection requirements of organic, high salt, high sensitivity, and HF acid resistance.
TEC Refrigerated Sampling Unit
The TEC sampling unit is a refrigeration cyclonic spray chamber of standard configuration, improves the continuous work stability and organic solvent analysis capability of the instrument, and reduces the oxide yield.
Full MFC Gas Control System
It adopts a highly integrated and high-precision digital MFC gas circuit controller, with a control accuracy of <0.5%. It can be configured with up to seven MFC channels. In addition to atomizing gas, auxiliary gas and cooling gas, additional dilution gas, auxiliary oxygen, Two-way collision gas, etc.
Argon On-Line Dilution System (AGOD)
It can inject regular samples as well as complex samples with high salt. When injecting complex samples with high salt, a second argon flow is added between the spray chamber and the torch tube to dilute the sample aerosol before entering the torch tube, reducing the total amount of sample entering the plasma. Direct analysis is possible without adding any diluent solution. The analysis results are stable and accurate.
12 Rotor High Precision Injection Peristaltic Pump
Standard configuration of 12 rotor high precision peristaltic pump, it can be configured with pump tubes of various materials such as PVC, Solva, Tygon, Viton, etc., to meet the needs of routine injection, organic solution injection, and long-life mode. The pump tube with a flared nozzle can be selected, which greatly reduces the difficulty of use.

Patented Self-excited All-solid-state ICP Ion Source
The patented self-excited all-solid-state RF power supply adopts frequency matching tuning and has a high tuning rate. Organic samples can be analyzed directly without moving parts, which are stable and reliable. It is driven in balance to achieve ion kinetic energy balance without the need for a shield torch.
● No need for matching box, fast frequency conversion in milliseconds to match plasma load changes, and it is not easy to flame out.

"Istandby" Standby Mode with Low Argon Consumption
During the suspension of analysis work, the instrument automatically standby with low power, greatly reducing the consumption of argon gas and electricity. When the sample is injected and analyzed, it will automatically return to normal working conditions.
③ Reliable Double Cone Ion Interface
The improved double-cone interface perfectly realizes the transition from ICP ordinary working atmospheric pressure to MS high vacuum, effectively reducing the load of MS vacuum pump. Efficient extraction and transfer of representative ions is achieved in the transition from the ultra-high temperature of the ICP ion source to the ambient operating temperature of the MS. Interface technology with two working modes, cone material is nickel or platinum material, optional.

Easy Handle Change Cone System
● Innovative handle-type cone changing system has interlock protection device to prevent abnormal operation.
● Replacing the cone is simple, allowing easy cone replacement and maintenance without breaking the vacuum.
④ Ion Deflection System
Schematic diagram of ion deflection transmission (schematic diagram of eliminating detection interference)
The ion deflection system consists of the first deflection lens, the collision / reaction cell and the second deflection lens. As shown in the figure above, ions and other particles move from right to left through the small hole in the middle of the double cone under the action of the extraction lens. Under the action of the first deflection lens, the ions are turned off-center. At this time, the photons that can only go straight are blocked and cannot reach the detector (to prevent photon interference). Likewise, neutral particles that can only go straight are received by the receiver and cannot reach the detector (to prevent neutral particle interference). Under the action of the deflecting lens, the electrons travel a different path than the ions, so they are separated and cannot reach the detector. After the ions turn off-center, they reach the collision/reaction cell. The polyatomic interfering particles are removed by a collision / reaction cell. The ions then turn under the action of the second deflection lens, return to the central axis, continue their journey, and reach the quadrupole mass analyzer....
