External Injection Module

Fast & Safe External Injection Module

For safe, fast and reliable handling of gas and LPG samples

Our ATOM INSTRUMENT™ EIM-1000™ External Injection Module is built for safe, fast and reliable handling of gas and LPG samples with seamless integration to the XT-2000 laboratory total sulfur – total nitrogen analyzer. The efficient and compact design reduces required benchtop space to a minimum, while allowing easy access to internal module components.  The EIM-1000 combined with the XT-2000 laboratory total sulfur – total nitrogen analyzer provides unmatched analytical performance making it suitable for a wide variety of applications and industries. 

The EIM-1000 External Injection Module can be used for both gas and LPG samples. Conveniently located valves and flowmeters allows users to adjust sample flow rate* for consistent sampling. The EIM-1000 incorporates the capability to provide pad pressure for sample cylinders to maintain compositional integrity of the product.


  • Increased sensitivity: Allows for the injection of larger sample volumes than traditional injection methods, which can improve the sensitivity and accuracy of analysis.
  • Reduced sample preparation: Can accommodate samples with high viscosity or particulate matter, reducing the need for manual sample preparation and handling.
  • Improved reproducibility: Provides a consistent injection volume and injection speed, which can improve the reproducibility and reliability of analysis.
  • Versatile: Can be used with a range of sample types, including liquids, gases, and complex mixtures, making it a versatile instrument for a range of applications.
  • Timesaving: Can automate sample injection, reducing the time required for sample analysis and increasing sample throughput.


  • Environmental monitoring: Used for the analysis of environmental samples, such as water, soil, and air, to detect contaminants and pollutants.
