Reduces Maintenance Frequency and Costs for Long-term Use

In addition to ultra-high sensitivity, the GCMS-TQ8050 NX also offers high robustness. The contamination-resistant ion source and the Because the GCMS-TQ8050 NX is able to detect ultra-trace ions with high sensitivity, it can also achieve high quantitative accuracy
new detector with over five times longer service life ensures that analysis can be performed reliably for a long time. With the even from trace sample quantities.
ultra-high sensitivity performance of the GCMS-TQ8050 NX, injection volumes can be reduced even further than before. The service Therefore, injection volumes can be reduced during analysis to reduce the analytical loads on the insert, column, ion source, and other
life of inserts, columns, and other consumables can also be extended to reduce maintenance frequency and costs. parts, and also further reduce maintenance frequency.

Oil-Free Pump (Optional) 7.0 7.5
The rotary pump can be replaced with an oil-free pump, which requires no maintenance for three years. This auxiliary vacuum pump
High-Performance Quadrupole Mass Filter not only maintains an oil-free environment inside the vacuum lines, it also eliminates the tedious and time-consuming tasks of
replacing and disposing of the oil.
The high-accuracy mass filter with pre-rods and patented electric field control technology achieves high-accuracy mass separation
performance. Clean exhaust due to dry method
Also, the pre-rods minimize quadrupole contamination and eliminate the need for quadrupole maintenance. using no oil in the pump chambers Year 0 Year 1.5 Year 3
Long-Life Detector Maintenance-free
Exhaustive efforts to reduce detector loads during analysis resulted in a
significantly longer detector service life. Consequently, the instrument needs to Overhaul
