VELP's brand new CN 802 element analyzer can determine the total nitrogen and carbon content of the cremated sample in one step. The device is also suitable for receiving solid and liquid samples.
Analysis time: approx. 3-4 minutes. The device can accommodate up to 117 samples in its sample changer, and after starting, it automatically performs the analysis of all samples.
With VELP's cloud-based IT system called ERMES, you can monitor the operation of the device from anywhere and at any time. The measurement data is managed and stored by a dedicated PC software. The PC must be ordered as a separate item.
The system works according to the following international standards: AOAC, DIN, ISO, EN, CEN, EPA, etc.

The new CN 802 can use two carrier gases. Since Helium is quite expensive, so where the use of Argon is permissible, it will be economical to use this carrier gas.
The detection limit of the device will be 0.01 mg Nitrogen in Argon carrier gas mode. The carrier gas has no effect on the carbon detection limit.
The gas connection of the CN 802 must be designed in such a way that the appropriate gas can be used as needed - by closing one tap and opening another.
