EMA 502 Elemental Analyzer working principle

EMA 502 Elemental Analyzer working principle

CHNS analysis begins with combustion of the sample in the VELP combustion furnace, above 1000 °C, to obtain elemental compounds.


VELP Vcopper™, a highly active copper powder, sits in the lower reactor to help reduce NOx to N2.


The flow then reaches the gas chromatography column oven, whose homogeneous, adjustable temperature fully separates the elements for final detection by TCD.


For oxygen analysis, the sample undergoes pyrolysis in the furnace, then passes through a chemical trap that absorbs all impurities before reaching the gas chromatography column and the TCD for detection.


    This combination does not exist.

    NDA 702 Dumas Nitrogen Analyzer
    VELP

    NDA 702 Dumas Nitrogen Analyzer

    Reference : VEL-F30800080

    Built to maximize your productivity


    The NDA 702 Dumas elemental analyzer suits high-throughput labs that need a fast, safe analyzer, with a choice of helium or argon as carrier gas.


    Powered by DUMASoft™ software, the NDA 702 produces N/protein results in just 3 to 4 minutes, fully unsupervised and cloud-enabled.


    The NDA 702 is much faster, easier and safer than a traditional Kjeldahl system.


    It is a safe analyzer that needs no aggressive chemicals or time-consuming steps: just prepare your sample and walk away.


    NDA 702 Nitrogen Analyzer Working Principle

    VELP NDA 702 Nitrogen Analyzer Working Principle

    The Dumas method begins with combustion of the sample in the VELP combustion furnace (CF), above 1000 °C, to obtain elemental compounds.


    Water is separated in two steps: first the maintenance-free physical trap DriStep™ (WT1) placed right after combustion, then a chemical trap (WT2) that removes the remaining 1% of water.


    Between the two traps, the gas flow passes through the reduction furnace (RF), where NOx compounds are converted into molecular nitrogen (N2).


    The CO2 is then trapped by the self-regenerating VELP CO2 adsorbers.


    Finally, elemental nitrogen is detected by the TCD LoGas™ thermal conductivity detector, which sends the data to DUMASoft™ to calculate nitrogen and protein content.


    Elemental Analysis and the Dumas Method

    The Dumas method (combustion method) is a primary method for determining nitrogen and protein, offering fast results, ease of use and safety. It is considered an alternative to the classical Kjeldahl method. Both are validated by international bodies: Kjeldahl is recognized by AOAC, EPA, DIN, ISO and others, and Dumas by AOAC, AACC, ISO, DIN, ASBC, AOCS, OIV and others. In some countries, local guidelines recommend one method over the other.

    The Dumas method for nitrogen determination (1831) is older than Kjeldahl (1883) but more convenient in many ways: speed, safety, cleanliness, productivity and cost per analysis.

    In the past, the conditions the Dumas method requires were hard to reproduce, so Kjeldahl took the lead and became the classical method for nitrogen/protein determination.

    Today, thanks to technological progress, Dumas nitrogen determination is becoming more widespread.

    • TC: Total Carbon
    • TOC, TIC: Total Organic and Inorganic Carbon (after acidification)

    • C/N Ratio


    The CN 802 is a safe analyzer with no aggressive chemicals or time-consuming steps: just prepare your sample and walk away.


    Set your next analysis and get a wealth of information from the sample.


    CN 802 Working Process

    VELP CN 802 Working Process

    The sample is purged with a carrier gas and drops into the combustion reactor, where it is converted into elemental compounds at high temperature (above 1000 °C).


    Water is separated in two steps. The combustion gases first reach the maintenance-free physical trap DriStep™ (WT1) after combustion, trapping 99% of the water; a chemical trap (WT2) then removes the remaining 1%.


    High temperature combined with the exclusive Vcopper™ reduces nitrogen dioxide to molecular nitrogen in the reduction furnace.


    The VELP HighSensIR detector covers a very wide carbon range, from a few ppm up to 150 mg of absolute carbon — from micro to macro applications.


    Auto-regenerating CO2 absorbers then trap carbon dioxide, letting the exclusive TCD (Thermal Conductivity Detector) measure the nitrogen content.
