JMS-TQ4000GC Triple Quadrupole Mass Spectrometer Model：JMS-TQ4000GC
The JMS-TQ4000GC constitutes a revolution in the field of triple quadrupole mass spectrometry. At the heart of the TQ4000 lies the unique short collision cell technology, which allows the TQ4000 to achieve ultra-high speeds and sensitivities. Within the short collision cell, precursor-ions are accumulated, fragmented and instantly discharged in a pulsed ion ejection. Combined with a gas chromatograph, the TQ4000 provides an advanced solution for a multitude of research and routine applications alike, such as pesticides residue or water trace analysis.

∎ Features
Three Technologies provide Accurate Quantitative Values Faster
Short collision cell that has capability of ion accumulation and pulsed ion ejection allows to achieve the high sensitive and high speed measurement. Measurement time can be reduced by high speed SRM switching, 1,000 transitions/sec, that is the fastest in the industry. It allows to improve the throughput of total analysis.
Technology 1 Ion Accumulation
The short collision cell accumulates the ions for a given short time and then eject them as pulse. Noise level of the signal can be reduced by synchronizing the timing between pulsed ion ejection and signal acquisition and that makes high sensitivity analysis possible.
Technology 2 Short Cell
Using the short collision cell makes it possible to eject all of ions accumulated in the cell very quick. That provides both of high sensitivity and high speed SRM switching that is the fastest in the industry without ion interaction among SRM channels (crosstalk).
Technology 3 Fast GC
Fast GC technique (using capillary column with small-diameter and short-length, using quick heating up rate for oven temperature) can reduce the measurement time, significantly expediting the routine analysis. Since the peak widths in the Fast GC chromatogram become narrow, high-speed transition are required. Short collision cell technology gives enough high speed transition for Fast GC measurement without any sensitivity loss.

Easier and Faster Data Analysis
Data Analysis software for Multi-Target compounds "Escrime™"
Being heedful of the real needs from customers, the data analysis software “Escrime™” was developed by focusing both of the simpler layout for easy to understand and the simpler GUI for easy to operate. Escrime™ software has many functionalities that can achieve what users are looking forward.
Slideshow for Data Check (Compound Slideshow Function)
Calibration curves, chromatograms and quantitative results for all target compounds and for all samples are automatically displayed on the screen. Users can check the all information without any action about their analysis and can stop the slideshow and edit the data analysis if necessary.
Easy Maintenance
Easy to clean-up the ion source, and Resume analysis quickly
No tools are required to remove the ion source from main body. High evacuation capability of vacuum pump make it possible to resume the analysis very quickly.
