Provides Higher Sensitivity and Reduced Operation Costs


A new turbomolecular pump with improved exhaust efficiency has been adopted. This significantly improves performance when not only helium but also hydrogen or nitrogen is used as the carrier gas. In addition, the differential exhaust system evacuates the ion source and quadrupole separately, thereby achieving the optimal MS state under all carrier gas conditions.

High Performance Ion Source


High sensitivity, stable analysis is achieved by incorporating patented technology for the ion source. In addition, the system is equipped with a Quick-CI function that enables checking molecular ions in CI mode without stopping the MS. This demonstrates its capabilities in both quantitative and qualitative analyses. * Limited to the NCI model.


Using patented technology, the shield plate suppresses the accelerating voltage and thermal radiation from the filament to achieve a space inside the ion source that is stable, with few active sites.  


Even though confirmation of molecular related ions is difficult with the EI method, data can be acquired by Quick-CI immediately without stopping the MS.

High-Performance Gas Chromatograph


Long-term stability is achieved for retention times thanks to AFC (advanced flow control) with built-in compensating technology for room temperature fluctuations. In addition, the constant linear velocity control mode keeps the linear velocity of the carrier gas constant even if the column oven temperature changes, so the best GC separation is always achieved.  



High-Speed Scan Control Technology Advanced Scanning Speed Protocol (ASSP™)


The rod bias voltage is automatically optimized during hight-speed data acquisition, which minimizes sensitivity deterioration during high-speed scans of 10,000 u/sec or faster. The sensitivity obtained is at least five times better than with conventional systems. This is effective for scan data sensitivity improvements and favorable mass spectrum acquisition, particularly in high-speed analysis with Fast-GC/MS, simultaneous Scan/SIM, FASST analysis, and applications using GC × GC-MS. (Patent: US6610979)


Chromatogram Intensities at Different Scan Speeds

At scan speeds of 10,000 u/sec and faster, the ions are accelerated at the optimal voltage using the ASSP function, thereby suppressing signal speed reductions across a wide m/z range.
