Thermo Scientific - smartEA™ The First Intelligent EA-IRMS

smartEA Mode^*
The combination of ConFlo IV and FlashEA builds the first intelligent EA-IRMS system.

In the smartEA mode the Thermo Scientific FlashEA reports the TCD (Thermal Conductivity Detector) responses to the Isodat™ software, which calculates the optimal dilution for each gas species in the sample. The ConFlo IV applies the dilution to each gas species matching sample and reference gas intensities.

Principle of IRMS
The measurement of isotope ratios requires that a sample gas is measured relative to a reference gas of a known isotope ratio. Signal intensities of reference and sample gas should be matched as closely as possible in order to achieve the best quality of data. The Thermo Scientific ConFlo IV matches the sample and the reference gas signals for highest precision and long term performance.

System Monitoring & Self Diagnosis
The ConFlo IV is designed to enable unattended operation of the Thermo Scientific Isotope Ratio MS over a long series of sequences which utilize different preparation systems. It is advantageous to determine system parameters such as stability, isotope linearity and H₃⁺ factor prior to the automatic start of a new application. The ConFlo IV applies these tests including storage, evaluation and application of the determined parameters. For the first time in Continuous Flow applications a fast and automated monitoring of system parameters is possible.
