Induction combustion for metals

An induction furnace above 2,000 °C with controlled power fully melts metals and inorganics, while a platinum-based catalyst and a heated dust trap give accurate carbon and improved sulfur recovery. Up to four infrared cells with variable cuvette lengths cover 0.6 ppm to more than 6 % at 1,000 mg, and intelligent lance oxygen management keeps dusty and low-density samples accurate — a nominal 40-second analysis.

About this product

The ELTRA ELEMENTRAC CS-i measures carbon and sulfur in predominantly inorganic samples with an induction furnace above 2,000 °C. Controlled induction power, a platinum-based catalyst reactor and a heated dust trap give accurate carbon and improved sulfur recovery; up to four infrared cells cover a measuring range from 0.6 ppm to more than 6 % at a 1,000 mg sample weight. Available as a single-element (C or S) or simultaneous C/S analyzer, with an optional 36- or 130-position autoloader and TIC module.

Why metals and metallurgy labs choose the CS-i

Induction combustion for metals and inorganics, from low ppm to percent level.

Induction furnace for metals

Combustion above 2,000 °C with controlled induction power fully melts metals and inorganics — including precise analysis of low-melting metals.

0.6 ppm to 6 %+ range

The latest detector technology and up to four infrared cells with variable cuvette lengths reliably cover 0.6 ppm to more than 6 % at 1,000 mg — with a two-cell configuration for both low and high levels.

Heated dust trap + Pt catalyst

A heated dust trap prevents water condensation and improves sulfur recovery; the platinum-based catalyst fully oxidizes combustion products for accurate carbon, even at very high levels.

~40 s analysis + autoloader

Nominal 40-second analysis, intelligent lance oxygen management for dusty and low-density samples, and an optional 36- or 130-position autoloader for high throughput.

Step 02

Install & train

Factory-trained engineers install the analyzer, connect oxygen, air and the PC/balance, and train your team on the ELEMENTS software.

Step 03

Method & QC support

We help build the SOP — calibration with standards, leakage test, blank control and a repeatable carbon/sulfur baseline.

What does the ELTRA ELEMENTRAC CS-i measure?

The ELEMENTRAC CS-i determines carbon and sulfur in predominantly inorganic samples — metals, alloys, ceramics, ores, cement and similar matrices. It uses an induction furnace above 2,000 °C to fully combust the sample, and up to four infrared cells to measure the released CO₂ and SO₂. It is available as a single-element analyzer for carbon or sulfur, or for simultaneous C/S measurement.

What is the measuring range and how is it configured?

With the latest detector technology, the CS-i reliably covers 0.6 ppm to more than 6 % at a 1,000 mg sample weight. Infrared cells use cuvettes of variable length — longer cuvettes give higher sensitivity for low concentrations such as 10 ppm, while a configuration of two IR cells for one element covers both low and high levels. Optional gold cuvettes, more robust high-sulfur cells and a halogen trap extend the range further.

How does the CS-i improve sulfur and carbon accuracy?

A heated dust trap collects the dust from inductive combustion and prevents water condensation, which significantly improves sulfur recovery and reproducibility. A platinum-based catalyst reactor with an extended reaction path fully oxidizes incomplete combustion products (carbon monoxide) for accurate carbon, even at very high concentrations. Intelligent lance oxygen management keeps dusty and low-density samples accurate.

Can the CS-i measure TOC and TIC?

Carbon can be reported as total carbon (TC) or in fractions — total organic carbon (TOC) or total inorganic carbon (TIC). Combined with ELTRA's TIC module, the CS-i measures TIC (for example lime) by acidification in products such as soil and construction materials. Additive Plus configures the TIC module to your application.

What automation and throughput options are available?

The induction furnace can be equipped with an optional automatic sample loader — 36 positions in the standard module, or 130 positions in the XL model, the largest autoloader available for this type of application. A software-based leakage test and the Windows-based ELEMENTS software (analysis, calibration, diagnosis, export) support reliable routine operation and high sample throughput.

What does the CS-i need to run?

It needs oxygen at 99.5 % purity (2–4 bar) and compressed air (4 bar), an external PC and monitor, and a balance with 0.0001 g resolution. It runs on 230 V, 50/60 Hz (max 15 A, 3,450 W). An optional vacuum system, also available with an H-class dust filter for potentially harmful samples, is offered. The analyzer measures about 520 × 840 × 750 mm.

What is the lead time, and can Additive Plus set it up?

The ELEMENTRAC CS-i is configured to order; request a quote for the current lead time. Additive Plus is an authorized ELTRA / Verder Scientific channel and handles installation, gas and balance connection, calibration and operator training, then helps build your carbon/sulfur SOP. You can also send a sample for a paid measurement first. Sub-4h reply, NDA on request.
