① Ion channel with independent intellectual property rights
Obtained multiple invention patents and has completely independent intellectual property rights; interactive automatic optimization of parameters greatly improves the automation efficiency and convenience of the instrument.
② Patented "giant energy bombardment" ion source
The pressure and temperature of the ion source are digitally adjusted and automatically controlled; the vertical orthogonal ion design is adopted to avoid direct droplet injection interface and improve the anti-pollution ability of the instrument; the efficient ion source exhaust gas discharge design is adopted to reduce matrix residue and background noise.
③ Patented "separation cone" interface technology
The internationally leading separation cone + backwash gas technology is adopted to enable the cleaning gas and exhaust gas system to continuously clean the ion source; the interface adopts a heating design to avoid sample and matrix residue.
④ High-precision mass analyzer
Equipped with a detachable pre-quadrupole, the structure is simple and easy to maintain; the main quadrupole is made of gold-plated metal molybdenum, and is processed and assembled at the micron level to ensure the stability of the instrument; the collision cell adopts quadrupole collision technology, and the radio frequency component technology is used for rapid scanning to ensure that there is no memory residue between different batches of ions.
⑤ Pulse counting detector
The international mainstream off-axis electron multiplier solution is adopted to reduce background noise; data is collected and transmitted alternately at nanosecond frequency to ensure data integrity is not lost; the linear range is up to 8 orders of magnitude.
⑥ Orthogonal design
The relative position between the spray needle and the interface adopts an orthogonal design, which greatly reduces the probability of complex sample matrix entering the vacuum system and ion channel. Even if complex samples such as blood samples and food are analyzed, the instrument has good tolerance.
⑦ Backflush technology
The interface uses high-purity nitrogen as backflush gas, which not only disperses ions to improve the sensitivity of the instrument, but also prevents the matrix from entering the ion transmission micropores. In addition, the heatable interface design means that even if trace amounts of contaminants are attached to the interface, they are quickly heated and volatilized.
