JEOL introduces mass spectrometer product

You are here: Home / Industry Feed / JEOL introduces mass spectrometer product

March 21, 2019 by realisma

The new JMS-TQ4000GC meets the needs for an ultrahigh-speed triple-quadrupole mass spectrometer. The spectrometer measures trace or residual pesticides in agriculture materials, trace levels of regulated chemicals in tap water, and simplifies quantitative analysis of persistent environmental pollutants such as dioxins and PCB’s.

The JMS-TQ4000GC achieves fast Selection Reaction Monitoring (SRM) switching speed in the industry at 1,000 channels/sec, allowing chemists to analyse multiple target compounds with high accuracy.

JMS-TQ4000GC

The product design features a new short-collision-cell technology that provides several benefits including ion accumulation with reduced noise level, rapid pulsed ion ejection without cross talk, and high-speed GC measurement that expedites routine analysis.

The short collision cell accumulates ions and ejects them in rapid pulses. The noise level of the signal is reduced by synchronising the timing between pulsed ion ejection and signal acquisition, making high sensitivity analysis possible.

Using small-diameter and short-length capillary columns enables rapid heating and reduces measurement time, providing faster routine analysis without loss of sensitivity.

With simultaneous multi-component analysis, chromatograms are arranged in a vertical column making it easy to compare samples. Combined with the compound slideshow function, the JMS-TQQ1000GC software makes it easy chemists to confirm all samples and components.

In addition to the standard electron ionisation source, the JMS-TQ4000GC also supports optional chemical ionisation and photoionisation sources, enabling easy acquisition of molecular weight information.
