Анализатор углерода / серы ELEMENTRAC CS‑i

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 .

Анализатор углерода / серы ELEMENTRAC CS-I Operation and Analysis Process

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

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

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

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

Анализатор углерода / серы ELEMENTRAC CS-I Configurations

The ELEMENTRAC CS-i is available as a single-element analyzer for carbon or sulfur only, or in a configuration for simultaneous measurement of both carbon and sulfur. It uses up to 4 IR cells which can be configured according to customer requirements. The longer the cuvette, the more sensitive it is for low concentrations like 10 ppm. Shorter cuvettes also allow measurement in the low ppm range, however with increasing standard deviation of the measured values. For optimum analysis of low and high concentrations, a configuration of two IR cells for one element should be selected. The latest detector technology permits advanced configurations to reliably cover the measuring range from 0.6 ppm to more than 6 % for a sample weight of 1000 mg. Optional gold cuvettes provide higher reliability for elemental analysis of halogenated samples. For reliable analysis of materials with a high sulfur content, the CS-i can be equipped with more robust IR cells to extend the measurement range and improve the reproducibility of the results. It is also possible to equip the CS-i with a halogen trap. Another option is a special configuration for measuring cement.

Анализатор углерода / серы ELEMENTRAC CS-I Integrated Standard Solutions

The chemicals and filters required for operation of the ELEMENTRAC CS-i are conveniently arranged on the front of the analyzer and may be concealed behind a removable door. This arrangement substantially reduces maintenance time and increases usability. Innovative details of the ELEMENTRAC CS-i significantly improve the reproducibility of carbon and sulfur measurements.

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

Анализатор углерода / серы ELEMENTRAC CS-i Options

In addition to the features already integrated in the ELEMENTRAC CS-i further options are available to increase efficiency and extend the application range.

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.

Анализатор углерода / серы ELEMENTRAC CS-i Принцип работы

In the induction furnace of the elemental analyzer the sample is melted in a pure oxygen atmosphere, causing sulfur to react to sulfur dioxide (SO₂) and carbon to a mixture of carbon monoxide (CO) and carbon dioxide (CO₂). The combustion gases pass through a dust filter and moisture absorber for purification. In the next step the sulfur dioxide is detected in infrared cells. In the CS-i infrared cells with different sensitivities (high/low) can be adapted according to the user’s requirements. Oxidation of both, carbon monoxide to carbon dioxide and sulfur dioxide to sulfur trioxide follow the sulfur measurement. The SO₃ gas is removed with cellulose wool; the carbon content is detected by infrared cells which can be individually customized. The ELEMENTRAC CS-i elemental analyzer can be equipped with up to 4 independent infrared cells.
