The elemental analyzer ELEMENTRAC CS-i measures the carbon and sulfur concentration in predominantly inorganic samples through combustion in an induction furnace and the subsequent analysis of the gaseous combustion products carbon dioxide and sulfur dioxide.

The high temperature of more than 2000 °C ensures complete decomposition of the sample and thus reliable and accurate elemental analysis over a wide concentration range.

The ELEMENTRAC CS-i meets and exceeds the requirements of all common standards for carbon and sulfur measurement, such as ASTM E1019, DIN EN ISO 15350 .

Step 1: Logging the sample into the ELEMENTS software

Step 1: Logging the sample into the ELEMENTS software

The sample ID is logged into the software and the weight is automatically transferred (see step 2).

Step 2: Weighing and adding of accelerators

Step 2: Weighing and adding of accelerators

Sample volumes of 50 mg to 1000 mg are typical for C/S analysis. The sample is weighed in a ceramic crucible and accelerators like tungsten are added. The geometry of the sample (e. g. wire, powder, pin etc.) is not essential for a reliable analysis.

Step 3: Analysis

Step 3: Analysis

The ceramic crucible is then placed on the pedestal and the analysis is started via the ELEMENTS software. The software controls all subsequent steps like combustion and evaluation.

Step 4: Data output and export

Step 4: Data output and export

45-60 seconds after the analysis has started, the measured carbon and sulfur concentrations are available for export as a report or via LIMS.

Catalyst

  • For accurate carbon determination
  • Extended reaction path ensures complete oxidation of incomplete combustion products (carbon monoxide)
  • Best possible reproducibility even for very high carbon concentrations

Heated Dust Trap

  • The dust generated by inductive combustion is collected in an external dust filter
  • Efficient heating of the dust trap prevents condensation of water vapor
  • Significant improvement of recovery rates and reproducibility of sulfur measurements

Intelligent Lance Management / Oxygen Supply

  • Individual control of the oxygen supply during inductive combustion
  • A lance flushes the entire oxygen flow to the center of the crucible to ensure complete oxidation of the carbon and sulfur contained in the sample (solid samples)
  • Oxygen flow is supplied through the combustion chamber to avoid swirling and loss of sample material (dusty samples)
  • Accurate analysis of low-density samples

Control of Induction Power

  • For optimized combustion of metals with a low melting point, such as copper, tin or magnesium
  • Reduced power in the induction furnace allows for safe and accurate analysis without sample loss through splashing during heating

Autoloader

The induction furnace of the ELEMENTRAC CS-i can be equipped with an optional automatic sample loader. The standard module offers 36 crucible positions, the XL model even features 130 positions. It is the largest Autoloader available in the market for this type of application.

TIC Module

Carbon can be determined as total carbon (TC) or in fractions, i. e. total organic carbon (TOC) or total inorganic carbon (TIC). When combined with the CS-i, ELTRA’s TIC module measures the TIC content (e. g. lime) by acidification in products like soil or construction materials.

TIC Module

The comprehensive Windows-based ELEMENTS software is an essential part of all ELEMENTRAC generation elemental analyzers.

A central window (analysis and results) is the starting point from which all functionalities required for the daily routine are easily accessible. From here it is possible to group and export analyzed samples, or register and analyze new ones. The user may call up various subordinate functionalities like application settings, calibration, diagnosis, or status.
