Elemental analyzer for every matrix   
multi EA® 2000




multi EA® 2000 Elemental analyzer

The Analyzer is designed for the determination of carbon, sulfur and chlorine in solid, pasty and liquid samples.

The multi EA® 2000 C analyzer is designed for the determination of carbon in solid,  pasty and liquid samples. The samples are digested in a high-temperature furnace in an oxygen stream, where the carbon compounds oxidize to carbon dioxide. An integrated Self Check System (SCS) enables trouble-free operation and ensures a high level of operation safety.

The freely selectable furnace temperature of up to 1,500° C ensures  complete digestion even of thermally and chemically highly resistant samples.

The high-temperature ceramic technology used does not only allow digestion at high temperatures, but also provides completely problem-free analysis of aggressive samples. Moreover, this technique is very cost-effective.

The wide dynamic weight range ensures optimum adaptation to the homogeneity of the samples and their carbon concentration.

Even with very inhomogeneous sample material, representative analysis is guaranteed. The produced carbon dioxide is measured by a high-grade NDIR detector that has a very large dynamic range.

Upgradable with:

  • FPG 21   
(solid sampler)
  • TIC solids module       
(direct determination TIC in solids)

multi EA® 2000 with additional furnace

Elemental analyzer for the determination of carbon and sulfur with additional furnace up to 500° C

The analyzer is adapted for the combustion of samples at two different temperatures: in the aditional furnace at temperatures of up to 500° C and afterwards in the high temperature furnace at temperatures of up to 1,500° C in an oxygen stream. The temperature of the additional furnace is freely selectable up to 500° C.

multi EA® 3100    

Elementar analyser multi EA® 3100 - top of the range-analysis of carbon, sulphur, nitrogen and chlorine

The multi EA® 3100 elemental analyzer represents a new generation of elemental analyzers for the determination of C, S, N and Cl in solid, liquid, paste, viscous and gaseous samples. It especially well suited for the analysis of petrochemical and related samples, such as oil, fuel, solvents, polymers, gas and liquid gas analysis, as well as fine chemical, EOX and AOX analytics.

At a glance:

  • Multi-element: Carbon, sulphur, chlorine and nitrogen determination in a single instrument
  • Simultaneous determination of nitrogen and sulphur
  • Automatic switching for chlorine measurement without retrofitting
  • Multi-range: Extended chlorine measuring range up into the percent range with a low maintenance combination electrode
  • Highly sensitive and stabilised coulometer cell for chlorine determination in the trace range
  • Unique sensitivity for S and N determination in the trace range
  • Ultra-modern detectors from ppb to the percent range
  • Multi-application: An analyzer for fluid samples, solids, gases and LPG
  • Optimised combustion with patented   flame sensor technology
  • Multi-matrix through double furnace technology: Vertical and horizontal operation for optimal adaptation to the sample matrix
  • Previously unattained high-sensitivity gas measurements
  • Multi-functional: A single autosampler for vertical and horizontal operation, fluid and solid samples
  • Multi Safety: Self Check System (SCS) for trouble-free operation
  • Simple operation with minimal maintenance
  • Multi-modular: Freely selectable and extensible combination of analyzer modules
  • Multi-conform: Conformity with a multitude of common international and national standards

Intelligent multi-element analysis with flame sensor technology:

  • No complex programming of feed speed
  • No adaptation of the gas flows and the gas composition necessary
  • No regulation of the combustion temperature needed
  • No prior knowledge of the sample combustion properties necessary
  • No system sooting
  • Improved precision through complete oxidation
  • Reduced matrix effects

Double Furnace:
To facilitate thermal oxidation of the samples, the furnace can be set up horizontally or vertically. Simple and fast changeover by the operating personnel. This means the respective advantages of each configuration can be fully exploited.

Besides highly sensitive UV fluorescence and chemiluminescence detectors, inexpensive electrochemical solid-state detectors are also available for sulphur and nitrogen determination, as well as coulometric sulphur determination. New, powerful and stabilised coulometers have been developed for chlorine determination over a wide measuring range. Carbon determination is selective and precise with the aid of an NDIR detector.

Multi-functional autosampler for every task
The autosampler enables fully automated determination of solid and fluid samples in vertical or horizontal furnace configurations. Simple changeover from fluid to solid samples and vice versa in just a few minutes.

Self Scheck System
The multi EA® 3100 comes equipped with the Self Check System (SCS) to safeguard trouble-free and fully automatic operation. The SCS checks and monitors all relevant parameters, which affect measuring results as well as the instrument and operating safety. Flame sensor technology is a fundamental component of the self check system.

Upgradable with:

  • Automatic inlet with cooled lock
  • All purpose autosampler APG 3100
  • Gas Sampling System
  • Liquified petroleum gas modul (LPG modul)
  • Autoinjector
