EMA 502 Elemental Analyzer CHNS-O

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, EMA 502 is extremely efficient and ensures the highest sample throughput thanks to the electronic autosampler and microbalance connection to the PC for direct weighing data transfer.

EMA 502 analyzes solid, semi-solid and liquid samples of up to 20 mg carbon content and minimizes operating costs thanks to VELP genuine consumables, carefully manufactured for the longest lifespan.

With just one powerful instrument and a quick configuration change, you will be able to successfully face multiple analytical challenges in elemental analysis.

Easily set and perform your CHNS analysis and then switch to O mode thanks to the exclusive connection panel!

The CHNS analysis starts with the combustion of the sample inside the VELP combustion furnace at a temperature higher than 1000°C to obtain elemental compounds.

VELP Vcopper™, a formulation of highly active copper powder, is placed in the lower part of the reactor to help the reduction of NO_X into N₂.

The flow then reaches the gas chromatographic column oven, which ensures homogenous and modular temperature leading to a complete separation of all the elements for the final detection by TCD.

When analyzing Oxygen, the sample undergoes pyrolysis inside the furnace and then passes through a chemical trap where all impurities are absorbed, before reaching the gas chromatographic column and the TCD for detection.

EMA 502 features the unique connection option to VELP Ermes Cloud Platform, the Smart Lab solution allowing you to reduce routine operations thanks to the real-time monitoring of your analyses wherever you are, at any time. 

Just by using a PC, a Smartphone, or a Tablet you can manage multiple instruments, consumables, workflows, analysis data, and instrument working conditions.

Immediate event and alarm notifications inform you about analyses and the remote analysis interruption guarantees total control of your laboratory processes. 

Grant access to instruments and data only to specific people in your organization and decide whether you like to share information directly with VELP or with authorized service centers to benefit from a reduced diagnostic time and enhanced service support resulting in the highest system uptime.

CHNS-O determination gets to a new level with VELP Ermes Cloud Platform.

EMA 502 Elemental Analyzer CHNS-O works with the innovative TEMS™ benefits, for unmatched savings.
