In the ICP, the polyatomic ions introduced by the solvent and sample matrix may result in serious interference in some target analytes. Therefore, the collision reaction cell (CRC) technology is used to eliminate this interference in quadrupole ICP-MS instruments. SUPEC 7000 is equipped with a new hexapole collision reaction cell system, which greatly enhances the interference elimination efficiency through collision, while maintaining the high-efficiency ion transmission capability. Combined with the ked working mode, SUPEC 7000 provides unparalleled performance in the simultaneous analysis of multiple elements in complex matrix samples.
The patented waterfall flow type distributed gas injection system can achieve gas replacement in the cell most efficiently and quickly. The system can, while improving the collision effect, greatly improve the gas replacement speed, and reduce the analysis waiting time.

Kinetic energy discrimination (KED) working mode: The energy loss of each collision between the ion to be measured and the He atom is the same as that between the polyatomic ion and the He atom; yet
since the polyatomic ion is larger than the ion under analysis, its chance of collision is therefore greater. At the outlet of the cell, the kinetic energy of the ion to be measured and the interfering ion is no longer the same due to the different times of collisions, and the polyatomic interfering ion will be blocked by potential well voltage blocking of at the quadrupole entrance due to the large kinetic energy loss, and won't be able to enter the mass analyzer.

The detection of trace V in blood samples is easily interfered by CIO ions. It is difficult to detect the level of V of < 0.1 ppb in the conventional collision cell. The SUPEC 7000's patented hexapole collision cell, in combination with KED, can be used to detect
trace V in the blood perfectly.

● Visualized operation monitoring
● Real-time display of key operation parameters
● Interlock protection is adopted for plasma in operation (argon, cooling water, ventilation, torch chamber, waste liquid, and temperature)
