XT-2000 is the most innovative laboratory analyzer on the market for reliable total sulfur and total nitrogen measurement on the market today. The XT-2000 laboratory analyzers are designed and built for precise, accurate and reliable analysis with the flexibility that allows the measurement of a wide range of samples with a single instrument.

• Includes patented Excimer UV technology
• Complies with ASTM D5453, D6667 and D4629, and EU certification
• Rapid Analysis and Response Time
• Capable of Running on Air
• Low Utility Consumption
• Versatility enables operation with either air or Oxygen-Argon mixtures for combustion
• Low Maintenance

The XT-2000 offers rapid analysis combined with the highest dynamic range on the market, which allows measurement of a broad range of samples with a single method using a single calibration. The efficient and compact design reduces required benchtop space to a minimum while maintaining complete accessibility to analyzer components.

Principle of Operation

Measurements start with the combustion of injected samples at high temperature (1050°C). For hydrocarbon species:  R-SH + R-NH + O₂ → SO₂ + CO₂ + H₂O

After removal of water (H2O), sulfur dioxide (SO2) is excited by the Excimer UV light emission, generating a secondary emission known as fluorescence which is proportional to total sulfur in the sample:  SO₂ + hv → SO₂^* → SO₂ + hv’

Nitrous Oxide (NO) produced during combustion is reacted with Ozone (O3) to generate a chemiluminescence emission which is proportional to total nitrogen in the sample:  NO + O₃ → NO₂ + O₂ → NO₂ + O₂ + hv’

Optional Modules To Add to the XT-2000- Expand Analytical Capabilities

The LAS-1000 Liquid Autosampler allows measurement of an extended range of liquids, gases and LPG products. The autosampler injects liquids and utilizes XYZ vectorized movement for sampling and injection for quick analysis. It is fully user-programmable to allow utilization of specified settings for intended samples. The direct screw drive Z-axis ensures the highest reliability throughout autosampler life.

The EIM-1000 is designed for injection of  gaseous and LPG  samples using a micro-electric actuator, eliminating the need for supplemental carrier for sample valve operation. Injected samples are carried from the EIM-1000 to the analyzer using specialized tubing, enabling optimal analytical performance. The EIM-1000 is generally installed adjacent to the XT-2000 analyzer and configured directly through the computerized user interface.

User Friendly Software & GUI

All XT-2000 laboratory analyzer systems include:

• Standard desktop computer and intuitive software that is both user-friendly and highly configurable.
• Various settings allow flexibility of method configuration and sample combinations that provide a maximum range of analysis.
• Calibration menus provide an array of charts and tables that reflect analysis results that include statistical computations that analyze the quality of calibrations.
• Calibrations can be updated without the need to re-run standards and with automatic reprocessing of analytical results.
• Export and print features allow easy access to data for storage, archiving and processing.
• Sample menus allow users to group samples where each sample may be run using a different method and calibration. This can facilitate analysis of sample groups by plant area or sample type and eliminate the need to set up groups for each calibration.
• Software comes with a preloaded “Idle” method that automatically engages according to user-defined parameters thereby minimizing utility consumption when the analyzer is not in use.
