For over 30 years, Elementar has been the German pioneer in high temperature TOC analysis. Elementar’s high temperature combustion method to measure organic contaminations provides a multitude of advantages compared to other methods. It is optimized to deal with compounds hard to oxidize, such as humic acid or other rather persistent compounds. This always guarantees full recovery of every organic component and an outstanding precision and accuracy.

Available models


The vario TOC cube has an optimized tubing and connection system that gives rise to a reliably, trouble-free handling of liquid samples containing particles. With the unique matrix separation concept, concentrated salt solutions can be analyzed even in larger injection volumes. In addition, the vario TOC cube is one of the very few analyzers on the market that allows measurement of solid and liquid samples with a single instrument – retrofitting is done within minutes.

Key features

  • Industry-leading performance and versatility
  • LOD of 3 ppb for TOC
  • Choice between three detection methods (IR, CL, EC) for nitrogen
  • Automatic sample feeding for solids
  • Unique matrix separation
  • Outstanding robustness
  • Integrated 50 position autosampler for liquids as standard
Vario TOC Select

The vario TOC select is designed for maximum robustness and minimal maintenance effort, thus providing industry-leading system uptime. The advanced matrix separation technology enables customers to run hundreds of samples without the necessity of maintenance work. For unattended overnight operation optional autosampler configurations with 60, 80 and 120 positions are available.

Key features

  • Industry-leading performance and versatility
  • Wide measuring range up to 100,000 ppm
  • Economic electrochemical detection for TNb
  • Automatic sample feeding for solids
  • Unique matrix separation
  • Outstanding robustness
  • Integrated 50 position autosampler for liquids as standard

In temperature programming, a precise, adjustable temperature is required for reproducible measurements. Thus in the soli TOC cube, the temperature is measured where it matters, directly at the crucible. This eliminates all possible thermal interferences. Additionally, the use of a post-combustion catalyst ensures that even samples with a high carbon content are quantitatively oxidized and achieve equally high measurement quality.

Key features

  • Measurement range of 0.001-100%
  • Fully automated analysis with 89 position autosampler
  • Temperature programming with fast heating rates
  • Optional carrier gas switching for better separation of ROC and TIC
  • Option to determine nitrogen simultaneously
  • Advanced crucible technology with automatic ash removal
  • Conforms to new (DIN 19539) as well as old (DIN 15936) standards for TOC determination in solids

With the new acquray series Elementar opens an entirely new way for easy Total
Organic Carbon (TOC) analysis and more. The technology is based on a chemical oxidation process supported by highly energetic UV radiation. This combination ensures complete digestion of all organic compounds. The modular concept allows the attachment of optional extra modules for the determination of TOC in solids, Total Nitrogen (TN) in water and Total Phosphorus (TP) in water. The instrument comes with predefined methods, completely calibrates itself automatically and auto-alerts the user any time maintenance is needed. This makes the acquray series the
ideal solution for routine labs that require instruments with high laboratory efficiency
and minimal down-time.

Key features

  • Easy to use
  • LOD of 2 ppb for TOC in water
  • Option for TOC, ROC and TIC in solids
  • Options for TN and TP in water
  • Optional autosampler with up to 109 positions
  • Best price-to-performance ratio
  • Low investment costs
