ATOM Instrument offers tools and accessories to meet the growing challenging needs and demands of the analytical world. The ATOM EIM-1000 External Injection Module is built for safe, fast and reliable handling of gas and LPG samples with seamless integration to the ATOM XT Series 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 series analyzers provides unmatched analytical performance making it suitable for a wide variety of applications and industries.]
- Meets ASTM D6667 and D4629 Requirements
- Exceptional Analytical Performance
- All-in-One Gas and LPG Module
- Electrically Actuated Valves
- Safe Operations
- Small Overall Size
- Full Integration with XT Series Software
Efficient Design
The EIM-1000 is available as either a lower pressure version (500 psi/35 bar) with flow meter for applications requiring verified sample flow or high- pressure sight glass version (1,000 psi/70 bar) for applications where extended sample pressures are required. The proprietary EIM-1000 sample transfer system ensures a low reactivity path for efficient transfer for optimal analytical measurement.
All-in-One Module
The EIM-1000 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.
Built-in Safety
- Relief valves ensure equipment integrity & operator safety
- Sample vent to allow discharge of unused product before removing samples
- All 24 VDC system to minimize electrical risks
- Heating elements below T3 temperature rating, typical of hydrocarbon autoignition temperature
- Electric valves to reduce instrument air usage
Easy to Use
The EIM-1000 operation is fully integrated with the XT Series and managed directly through the Laboratory User Interface (LUI). The LUI software operates the electrically actuated gas and LPG valves independently while giving users full control over the analyzer operations.
