ELEMENTRAC CS-d  Sulfur/Carbon Analyzer

ELEMENTRAC CS-d Sulfur/Carbon Analyzer

Eltra | Material Characterization

ELTRA's ELEMENTRAC CS-d is the only analyzer in the market for determination of carbon and sulfur  in organic as well as inorganic samples. For this purpose, the ELEMENTRAC CS-d is equipped with both an induction and a resistance furnace (ELTRA Dual Furnace Technology), covering the full range of carbon and sulfur analysis.

Up to four highly sensitive infrared (IR) cells allow for precise measurement of both high and low carbon and sulfur concentrations in only one analysis. The measuring range of each cell may be adapted to the user's specific requirements to ensure optimum measurement conditions for each application.

The ELEMENTRAC CS-d is supplied with the comprehensive and user-friendly ELEMENTS software which features statistics, groupings, reports, diagnosis tools and many additional functions.

APPLICATION EXAMPLES

alloys, ashes, carbides, cast iron, cement, ceramics, coal, coke, copper, glass, gypsum, iron, limestone, metals, minerals, oil, ores, plant materials, refractory metals, rubber, sand, soils, steel, titanium, tobacco, ...

FUNCTION PRINCIPLE

Operation Carbon / Sulfur Analyzer ELEMENTRAC CS-d

The ELEMENTRAC CS-d utilizes two different furnaces (resistance and induction) which share one detection unit consisting of up to four independent IR cells. Inorganic samples like steel, cast iron, cement are usually processed in the induction furnace of the CS-d. After applying the sample to a ceramic crucible, it is logged in the ELEMENTS software with name and weight. This is followed by adding accelerators like iron and tungsten. The ceramic crucible with sample and accelerator is placed on the pedestal and the measurement is started in the software. All further steps are controlled by the ELEMENTS software; the measured carbon and/or sulfur result is displayed after approx. 50 seconds. One or multiple results can be exported to LIMS or to a report.

Organic samples are usually processed in the resistance furnaces of the CS-d at a defined temperature up to 1,550 C. The samples (such as coal) are weighed in ceramic boats without accelerator. The weight is transferred from the interfaced balance to the PC or can be entered manually. The sample is then placed directly on the balcony in front of the furnace and the measurement can be started. A green LED light indicates when the analyzer is ready for measurement and the ceramic boat with the sample can be introduced into the hot furnace with the help of a stick. The typical analysis time is 60 to 180 seconds, depending on the sample material.
