JMS-TQ4000GC
Triple-Quad Mass Spectrometer

The JMS-TQ4000GC Triple-Quadrupole Mass Spectrometer accurately measures trace or residual pesticides in agricultural materials, trace levels of regulated chemicals in tap water, and simplifies quantitative analysis of persistent environmental pollutants such as dioxins and PCB’s.

JMS-TQ4000GC

The JMS-TQ4000GC allows chemists to look at hundreds of samples quickly and obtain detailed analyses of target compounds.

It achieves the fastest Selected Reaction Monitoring (SRM) switching speed in the industry at 1,000 channels/sec. Chemists can analyze multiple target compounds with high accuracy.

Fast and Accurate Quantitative Values

The JMS-TQ4000GC offers three distinct technologies for high speed analysis:

  • Ion Accumulation - the short collision cell accumulates ions and ejects them in rapid pulses. The noise level of the signal is reduced by synchronizing the timing between pulsed ion ejection and signal acquisition, making high-sensitivity analysis possible.
  • Short Cell - the short collision cell accumulates the ions for a given short time and then ejects them in a pulse. The noise level of the signal can be reduced by synchronizing the timing between pulsed ion ejection and signal acquisition, making high-sensitivity analysis possible.
  • Fast GC technique – By using a capillary column with a small diameter and short length with a fast oven temperature ramp, the TQ4000GC can reduce measurement time, significantly expediting routine analysis. Because the peak widths in the Fast-GC chromatogram are narrow, high-speed transitions are required. Short collision cell technology provides enough high-speed transitions for Fast-GC measurement without any sensitivity loss.

Easier and Faster Data Analysis

With an easy-to-read layout and simple operation, the TQ4000GC data analysis software "Escrime™" was developed for simultaneous multi-component analysis. Chromatograms are arranged in a vertical column making it easy to compare samples. Combined with the compound “slideshow” function, the Escrime software makes it easy for the chemist to confirm all samples and components.

Wide Range of Organic Analyses

In addition to the standard electron ionization (EI) source, the JMS-TQ4000GC also supports optional chemical ionization (CI) and photoionization (PI) sources, enabling easy acquisition of molecular weight information. The system is not limited to just GC-MS and can also do 2 types of direct probe experiments: direct insertion probe (DIP) for insoluble compounds and direct exposure probe (DEP) for high boiling point and labile compounds.

Easy Maintenance

No tools are required to remove the ion source from main body. The high pumping capacity of the vacuum system makes it possible to resume analysis very quickly.

Three Technologies Providing Accurate Quantitative Values Faster

The short collision cell has the capability of ion accumulation and pulsed ion ejection allowing the user to achieve the highest sensitivity and high speed measurement. Measurement time can be reduced by high speed SRM switching at 1,000 transitions/sec, the fastest in the industry. This allows the user to improve throughput for total analysis.

Technology 1 – Ion Accumulation

The short collision cell accumulates the ions and generates a pulse. Data is acquired only when an ion pulse occurs and not acquired at other times when there is only noise, thus significantly improving the signal-to-noise ratio. Delivers unprecedented high sensitivity and reproducibility.

Technology 2 – Short Cell

Using the short collision cell makes it possible to instantaneously ejects all of the ions within the cell. This provides both high selectivity with the elimination of interfering ions, as well as the industry’s fastest SRM.

Short Collision Cell Technology

Technology 3 – Fast GC

Using small-diameter, short capillary columns and rapidly increasing the temperature of the GC oven enables shorter measurement times, significantly improving the number of samples that can be processed per hour. Since the peak widths in the chromatogram are decreased, high-speed transitions are required, which is where the capability of the short collision cell really shines.

Easy Maintenance

Easy to clean-up the ion source, and Resume analysis quickly

  • No tools are required to remove the ion source.
  • Since the vacuum pump has a high evacuation capability, the measurement recovery time is extremely short.
