2400 Series II CHN/O Elemental Analyser2400 Series II CHN/O Elemental Analyzer

Company: Perkin Elmer

General description

The PerkinElmer 2400 Series II CHNS/O Elemental Analyzer is a powerful instrument for the rapid determination of the carbon, hydrogen, nitrogen, sulfur or oxygen content in organic and other types of materials. Based on the classical Pregl-Dumas method, samples are combusted in a pure oxygen environment, with the resultant combustion gases measured in an automated fashion. High-speed microprocessor control, solid state components and built-in diagnostics provide confidence in performance and reliability.


  • One analyzer with three possible modes of operation: CHN, CHNS and Oxygen (sulfur detection is not currently available).
  • Fast analysis times: a typical CHN analysis is accomplished in under six minutes, CHNS in eight minutes and oxygen in four minutes.
  • Advanced combustion design for handling virtually any type of sample.
  • Frontal Chromatography for simple, reliable and accurate measurements.
  • NEW EA 2400 Data Manager software for easy data handling.

The Praying MantisTM(DRP) accessory

Company: Harrick

The Praying MantisTM was the first generally available diffuse reflection (DRIFTS) attachment and remains the forerunner in the field. It incorporates two 6:1, 90° off-axis ellipsoids which form a highly efficient diffuse reflection illumination and collection system. This unique configuration deflects the specular reflectance away from the collecting ellipsoid, minimizing the associated spectral distortions. The Praying MantisTM also can be configured to study materials and reactions in controlled environments with the appropriate diffuse reflectance reaction chamber.

The applications are:

  • Easy and reliable diffuse reflection analysis of solids and powders by FT-IR and UV-VIS spectroscopy
  • Analysis of catalysts and other powders in a temperature and/or pressure controlled enviornment
