EMIA-20XC High-Concentration Carbon Analyzer

Highly Repeatable Carbon Analysis for Precise Control of High-Carbon Materials

Precise control of carbon concentration is critical in the production of tungsten carbide and other carbon-containing powders.
The EMIA-20XC from EMIA-Expert series is designed for the precise analysis of high-carbon-content materials, delivering accurate, highly repeatable results and reliable long-term reproducibility. Its dedicated XC detection unit, optimized for high-carbon applications, minimizes the effects of atmospheric pressure and temperature fluctuations, enabling consistent measurements in a short time. The built-in switching function also enables the analysis of carbon and sulfur at low-ppm concentrations, combining high-concentration carbon analysis with versatile carbon/sulfur measurement in a single system.

Main Features

RSD ≤ 0.15% and approximately 160 seconds in XC Mode

In XC Mode, the analyzer achieves a relative standard deviation (RSD) of ≤ 0.15% for high-carbon-content materials such as tungsten carbide. Results are displayed in approximately 160 seconds from measurement start.

2-in-1 Cemented Carbide Carbon and Inorganic Carbon /Sulfur Determination

By switching the modes, the EMIA-20XC supports both high-concentration carbon analysis and low-concentration carbon and sulfur analysis.

Optional autosampler is available.

Proprietary Technology for High-Repeatability Measurement

The detection unit (XC unit), specialized for measuring high-carbon-content materials, minimizes the effects of atmospheric pressure and room temperature fluctuations, enabling high-repeatability measurements in a short time.
Relative standard deviation (RSD) ≤ 0.15%, demonstrating outstanding reproducibility, for high-carbon-content materials, such as tungsten carbide.
Approximately 160 seconds from measurement start to results display: high-repeatability measurement mode (XC mode).

The Gas Flow

The EMIA-20XC enables switching between high-repeatability measurement of high-concentration carbon and measurement of low-concentration carbon and sulfur.

Applications*

*Application examples are based on representative evaluations conducted with EMIA-20XC and/or EMIA-Pro/Expert. Results and repeatability depend on sample composition, homogeneity, concentration, particle size, pretreatment, calibration, and other measurement conditions. The specified RSD 0.15% applies only under the specified measurement conditions and is not guaranteed for all sample types. Please contact HORIBA before purchase to confirm the feasibility of your application and recommended measurement conditions.
