VELP EMA 502 Elemental Analyzer CHNS-O
The all-in-one CHNS/O solution to broaden your analytical potential
EMA 502 Elemental Analyzer CHNS-O is the accurate and reliable solution for the determination of carbon, hydrogen, nitrogen, sulfur, and oxygen in various industrial sectors such as pharma and life science, organic chemistry, petrochemistry and energy, environmental, agronomy, food & feed.
CHNS-O analysis with EMA 502 helps determine the structure of an unknown compound and evaluate the structure and purity of synthesized compounds.
Working in accordance with official reference methods, EMA 502 performs CHNS and Oxygen determination in minutes without requiring additional modules.
EMA 502 is safe, requiring no aggressive chemicals or time-consuming steps.
Versatility and productivity with exclusive operating comfort
EMA 502 is engineered to work 24/7, 365 days a year unattended with fast and easy routine maintenance.
Processing up to 117 samples at a time, it ensures the highest throughput via electronic autosampler and microbalance PC connection.
Analyzes solid, semi-solid, and liquid samples up to 20 mg carbon content, minimizing operating costs with genuine VELP consumables.
Switch easily between CHNS and O modes via the exclusive connection panel.
Consistent performance, proven accuracy and tested reliability
EMA 502 is a flexible and robust analyzer designed for superior reliability and accuracy.
TCD detection technology ensures reproducible results with RSD ≤ 0.2% (Sulphanilic acid).
Results are automatically calculated by EMASoft™ software receiving real-time data.
Gas chromatographic column and TCD enable real-time view of the analytical process for the entire instrument lifespan.
EMA 502 Elemental Analyzer working principle
CHNS Flowpath
CHNS analysis starts with combustion of the sample inside the VELP furnace (>1000°C).
VELP Vcopper™ aids reduction of NOx into N₂.
The flow reaches the gas chromatographic column oven for complete separation and final TCD detection.
For Oxygen analysis, the sample undergoes pyrolysis, impurities are trapped chemically, then detected by TCD.
Unmatched ease-of-use and data security with EMASoft™ software
EMASoft™ software controls and operates the EMA 502 analyzer with a user-friendly interface showing results, database, and instrument conditions.
Features include:
- Pre-installed and customizable methods
- Easy calibration curve creation
- Start analysis with few clicks
- Animated tutorials for quick configuration
- Real-time TCD gas graph display
- Maintenance alerts and detailed result tables
Optional 21 CFR Part 11 Package available for FDA-regulated laboratories.
