The determination of surface carbon is a special requirement for quality control in the metal-producing and metal-working industries. ELTRA’s SurfaceC-800 analyzer is designed for the precise determination of surface carbon in numerous kinds of solid samples from trace levels up to 1000 µg/cm2.

The ELTRA SurfaceC-800 is equipped with a resistance furnace with a quartz tube for sample oxidation and can provide temperatures up to 1000 °C. The temperature of the SurfaceC-800 can be set up in steps of 1 °C. As common carrier gas in the SurfaceC-800 oxygen is used.

The detection system of ELTRA’s SurfaceC-800 is very sensitive, and reliable, and guarantees a long lifetime. It can be customized according to the user’s requirements. It is possible to combine two infrared cells independently to allow for highly precise measurement of surface carbon from trace level up to large amounts

Function Principle

Operation of the SurfaceC-800 is simple and convenient. The temperature of the SurfaceC-800 is set up to a defined temperature up to 1000 °C. After entering the sample surface size in the PC, the sample is placed in a quartz boat. In the following, the analysis can be started and the sample boat is pushed from the open end of the combustion tube into the hot zone of the furnace. The combustion gas is led through a copper oxide catalyst and the formed CO2 is determined by the infrared cells. All data processing, control of the combustion process, and calculating of the result is done by an external PC. The CO2 determination only takes about 60 to 90 seconds.

About Eltra

The development of the first carbon and sulfur analyzer in 1981 marked the beginning of ELTRA’s success story 40 years ago. From day one, the focus was on the design of analyzers for the precise determination of C, H, N, O, and S element concentrations in solids.

Over the years, the product portfolio was further expanded and refined, for example by adding thermogravimetric analyzers in 2007. Our goal has always been to design combustion analyzers that are characterized not only by high precision and detection sensitivity but are also robust enough to provide reliable measurement results under rough conditions. The new generation of ELEMENTRAC analyzers impressively combines this claim with state-of-the-art technology and ease of use. The excellent price-performance ratio of our products together with our fast and reliable technical service helped ELTRA to continuously gain market share over the past four decades. Today, we are represented in more than 80 countries by a broad sales & distribution network.

In 2012, ELTRA became part of the VERDER Group and was integrated into the Scientific Division, which is home to renowned companies from the laboratory & analytical sector, including Retsch and Microtrac. Under the new management, substantial investments were made in new products and services for C/H/N/O/S elemental analysis and macro thermogravimetry. Customers in quality and analysis laboratories as well as research departments appreciate the speed, precision, and ease of use of our analyzers.

Our past experience and achievements motivate us to continue developing new analyzers. Securely positioned for the future, we will integrate new technologies into our portfolio which will allow us to conquer new markets over the next 40 years.
