Superior Performance
High Efficiency in a Variety of High-Sensitivity Analysis
A new turbomolecular pump with higher evacuation performance achieves a superior vacuum state in the MS unit, which also Detection with High Separation by High Mass Resolution
provides high sensitivity in the single GC-MS mode. With the high-efficiency collision cell (UFsweeper) installed as before,
high-sensitivity detection is possible even when mass resolution is increased. In many cases, even using MRM analysis does not provide sufficient separation for quantitative analysis of ultra-trace compounds in biological
The new active-time management function achieves further operating efficiencies by appropriately managing the wait times samples or food samples that contain large amounts of impurities, for example. Using the GCMS-TQ8050 NX, compounds can be detected
(downtime) that occur during maintenance, while switching systems, or when the system is used by multiple users, to extend the with high sensitivity even if high mass resolution is specified. Therefore, it can clearly detect even compounds that previously could not be

A new automatic flow controller (AFC) with a CPU uses various control methods to control (2 ng/mL concentration in urine)
carrier gas flow to a constant flow speed, flowrate, or pressure. It can also accurately trace the
analytical conditions already being used.
In addition, the split line filter can be replaced without any tools. Internal contamination can
be confirmed visually to ensure filters are replaced at the proper timing.

UFsweeper High-Efficiency Collision Cell The UFsweeper high-efficiency collision cell and Q1 unit detect generated ions efficiently. That achieves high sensitivity not only for MRM measurements in the GC-MS/MS mode, but also for
scan and SIM measurements in the GC/MS mode as well. In addition, pre-rods help prevent quadrupole contamination, so that stable
