How does EST work?

• EST works by decreasing the electron energy below the ionization threshold of the gas of interest. This means that no ionization occurs as the sample is introduced (dark phase).
• With EST, the signal stability either side of the dark phase is reproducible within 0.1%.
• Switching from the dark phase to the measurement phase is very fast (<1s)

Advantages of EST

• Start your data collection at t0.
• Achieve the same excellent precision irrespective of equilibration time.
• Dramatically decrease sample size.
• No equilibration time dependency on isotope ratio accuracy.

Push the limits of NG-MS with EST

EST allows a greater degree of flexibility of analytical methods and prep designs.

• Boost your precision: Dramatically increase signal sensitivity by decreasing the volume of the prep system. Equilibration times can be extended as long as necessary.
• Kr and Xe without trade-offs: the long equilibration times of Kr and Xe are now no longer a problem. Equilibration times can be extended as long as necessary with no impact on analytical precision.
• Method flexibility: get a quick snapshot of the ion beam and to switch between ion counters or Faraday detectors depending on the size of the ion beam.

Method flexibility: Perform on-peak baselines during sample analysis with no sacrifice to analytical precision.
