VELP EMA 402XL Macro CHNS Analyzer

The VELP EMA 402XL Macro CHNS Analyzer is a high-performance elemental analysis system designed for the simultaneous determination of Carbon (C), Hydrogen (H), Nitrogen (N), and Sulfur (S) in a single configuration. Developed for laboratories that work with large and demanding solid or liquid samples, the EMA 402XL combines high-temperature combustion technology, advanced detection systems, and automated sample handling to provide an efficient and reliable solution for macro elemental analysis.

With its ability to directly analyze extra-large solid or liquid samples up to 3 grams, the EMA 402XL is particularly suitable for laboratories requiring high sample capacity and efficient analysis without the need for extensive sample preparation.

Advanced Macro Elemental Analysis

The EMA 402XL is designed as a macro elemental analyzer capable of simultaneously determining C, H, N, and S within a single analytical configuration. This integrated approach allows laboratories to perform multiple elemental determinations efficiently while simplifying the overall analytical workflow.

The analyzer is designed for applications where accurate elemental composition data is required for research, quality control, characterization, and routine laboratory analysis.

Integrated 100-Position Electronic Autosampler

The system features an integrated 100-position electronic autosampler, enabling laboratories to process multiple samples in an organized and automated sequence.

The large sample capacity helps reduce manual intervention and allows users to set up extended analytical sequences, making the EMA 402XL well suited for laboratories handling a high volume of samples.

Key advantages include:

• 100-position electronic sample capacity
• Automated sample handling
• Reduced manual intervention
• Efficient batch analysis
• Improved laboratory productivity
• Convenient sequential sample processing

Dynamic Reagent-Free Vertical Furnace

The EMA 402XL features a dynamic, reagent-free vertical furnace capable of reaching temperatures up to 1350 °C.

The high-temperature furnace provides the conditions required for effective combustion and elemental determination. Its reagent-free configuration can help simplify laboratory operation and reduce the need for additional chemical reagents during the analytical process.

The vertical furnace design provides an efficient environment for processing large samples while supporting consistent analytical performance.

Advanced Detection Technology

The EMA 402XL uses dedicated detection technologies for different elements, providing an optimized approach to elemental quantification.

NDIR Detection for Carbon, Hydrogen and Sulfur

Carbon, Hydrogen, and Sulfur are quantified using separate NDIR (Non-Dispersive Infrared) detectors.

The use of dedicated NDIR detection provides an efficient method for measuring the relevant combustion gases generated during elemental analysis.

TCD Detection for Nitrogen

Nitrogen is measured using a Thermal Conductivity Detector (TCD).

The TCD provides reliable detection of nitrogen and complements the NDIR detection system used for carbon, hydrogen, and sulfur.

Together, these detection technologies allow the EMA 402XL to perform comprehensive CHNS elemental analysis within a single system.

Direct Analysis of Large Samples

One of the key features of the EMA 402XL is its capability to perform direct analysis of extra-large solid or liquid samples up to 3 grams.

This makes the analyzer particularly useful when working with samples that are difficult to reduce to very small quantities or when larger sample quantities are desirable for analytical purposes.

The ability to accommodate larger samples can provide greater flexibility for laboratories working with different sample types and compositions.
