With the NDA 702 you can load different matrix of solid, semi-solid and liquid samples at the same time.
VELP NDA 702 elemental analyzer is designed to work 24/7, 365 days a year with fast and easy routine maintenance.
The autosampler is supplied with a disc of 30 positions and can be expanded to accommodate up to 117 samples.
The lowest LOD in the market of 0.001 mgN with Helium and the RSD lower than 0.5% (EDTA) assure you high precision results and excellent reproducibility.
NDA 702 analyzes samples of up to 1 g and reduces operating costs thanks to VELP engineering and genuine consumables with extended lifetime. Furthermore, NDA 702 allows cost reduction related to Helium availability thanks to the seamless choice of Argon.
The Dumas method starts with the combustion of the sample which takes place inside the VELP combustion furnace (CF) at a temperature higher than 1000°C to obtain elemental compounds.
Water separation is performed in 2 steps in the NDA 702. The first is the maintenance-free physical trap DriStep™ (WT1) strategically placed after combustion and the second is a chemical trap (WT2) that ensures the complete elimination of residual 1% of water.
Between the two traps, the flow of gases passes through the reduction furnace (RF) where NOX compounds are transformed into molecular nitrogen N2.
Afterward, the CO2 is trapped by the unique self-regenerating VELP CO2 adsorbers.
At this point, elemental nitrogen is detected by the innovative thermal conductivity detector TCD LoGas™ which will send the data to DumaSoftTM to calculate the amount of Nitrogen and Protein.
We have designed the NDA 702 to ensure maximum ease of use with DUMASoftTM's intuitive User Interface. Control the status of the instrument for the main window, at a glance.
Setting up an analysis is extremely simple. The database and real-time graph are easily accessible and with the connection to a balance the preparing a test is even faster.
The DUMASoftTM contains an extensive library of preinstalled methods, multilingual support and reporting functions with export to .csv, LIMS e.xls format.
Create and manage calibration curves, assign a name and always be ready to use the most suitable one.
Run the complete Leak Test and choose whether to run it on the whole circuit or targeted by zone, after replacing a consumable for example.
NDA 702 thanks to its connectivity to VELP Ermes allows you to reduce routine operations thanks to the real-time monitoring of your elemental analyzer wherever you are, at any time.
NDA 702 is designed for continuous work with fully automated processes, VELP Ermes allows you to manage multiple instruments, consumables, workflows and to drastically reduce diagnostic time to ensure a superior level of service with maximum data security and protection of your data.
Immediate notifications and alerts will allow you to be always informed about the status of your analysis and thanks to the remote interruption you will have total control of your processes ensuring maximum security.
Access the database of your instrument in total security through the VELP Ermes platform and work with your colleagues creating and sharing reports from PC, smartphone and tablet.
