ICP-MSMS 7350

The world's first vertical torch

The vertical torch design is introduced in ICP-MS for the first time, which greatly reduces the accumulation of salt in the torch, prolongs the service life of the torch, and solves the problem of analyzing high-salt complex matrix samples. At the same time, argon consumption is greatly reduced, and heat and exhaust gas naturally enter the exhaust system upward, requiring less cleaning and less downtime.

A new generation of all-solid-state ion source

The unique patented dual RF power supply has the fastest impedance matching mode, which makes the response faster and the anti-interference ability stronger. Without any moving parts, it provides a more stable ICP torch, and improves the stability of the analysis while being small in size. It can be directly injected to analyze 100% ethanol and other highly volatile organic compounds.

Combined with ultra-high matrix direct injection system and organic injection system, it can ensure long-term stable and reliable analysis in any complex matrix.

It is specially designed for the analysis of high-salt samples, with strong matrix tolerance, and has two modes of high-salt sample injection and on-line dilution.

High-salt tolerance mode: direct sample injection to analyze high-salt samples with a salt content >10% to improve analysis efficiency.

On-line dilution mode: samples with content in percent are directly injected for analysis, which perfectly solves the limitation of ICP-MS in the analysis of high content.

Perfect cold plasma mode

The unique self-excited all-solid-state RF source provides cold flame mode as low as 500w, reduces the ionization of Ar-based ions, improves the signal-to-noise ratio of analyte ions such as 39K+, 40Ca+, 56Fe+, and the lower limit of detection of elements is greatly extended.

With the matrix-resistant vertical ion plasma design, combined with the new generation of self-excited all-solid-state RF power supply and the ultra-high matrix direct injection system, it can still guarantee the long-term stability of the instrument even in the face of soil solution with complex matrix, to avoid signal drift caused by the matrix and ensure the accuracy and reliability of data.

Embedded cylinder design

• The shortest gas pipeline design can quickly realize gas replacement and meet the needs of high-throughput analysis

• It can be configured with 5-channel collision reaction gas, and supports any ratio on-line to meet the application requirements in various scenarios.

• There is no need for an external gas cylinder, saving laboratory space and providing a more friendly experimental environment.

Three turbomolecular pumps and five-stage vacuum design

• Provide higher vacuum, and increase ion transmission effectiveness.

• The vacuuming time is shorter and the efficiency of the instrument is improved.

• Differential vacuum design to reduce ion transmission loss.

• Reduce the load of molecular pump and improve the service life of turbomolecular pump.

The strong analytical capability creates unparalleled analytical performance, and each sample can be tested and analyzed under the most suitable conditions.

Flexible analysis mode

EXPEC 7350 ICP-MS/MS gives full play to the potential of the collision reaction cell. The five-channel collision reaction gas combined with MS/MS mode can ensure sensitivity, completely eliminate interference, and obtain accurate results even when analyzing samples with extremely complex matrices:

• SQ analysis mode: consistent with the traditional ICP-MS analysis mode, Q1 makes all ions pass through

• TQ mass screening analysis mode: Q1 and Q2 screen the same mass number

• TQ mass transfer analysis mode: Q1 and Q2 screen different mass numbers

True triple quadrupole design

• Q1 and Q2 use pure molybdenum quadrupoles of the same specification, providing extremely high mass selectivity and quadrupole stability

• The longest quadrupole in the industry is used to increase the number of ion vibrations and improve the resolution, with the mass resolution of less than 0.3amu

• The ultra-wide bandpass function increases the sensitivity of the instrument by more than 2 times

The third generation of high-speed dynamic collision reaction cell

• With waterfall-flow distributed inlet collision reaction cell, the collision reaction gas is introduced orthogonally throughout the collision reaction cell, with small cell volume and high ion transmission efficiency

• The new waterfall-flow collision/reaction gas diffuses in the cell to form a good gas distribution, and only 30% of the gas flow can achieve the same effect as other collision reaction cell, greatly improving the efficiency of collision reaction and sensitivity

• Five-channel collision reaction gas can be configured to meet the requirements of trace analysis in various complex matrices and application scenarios

Secondary off-axis design

• The ion to be measured will be deflected 180 degrees to completely separate from the matrix particles, reduce the background of the instrument, and greatly improve the signal-to-noise ratio

• Specialized neutral particle receiver is used, and the ion optics are maintenance-free for life
