Hi there

[dong zhang]

Thanks for your kind work to provide such a good software in partionning nitrate sources in natural waters. Here, we wandered that if you can expand the parameters in the frame, such as five isotopes simultaneously applied in the frame. thanks 

We thanks for your help, if you have any questions about my asking, please email me, and my email address is zhangd...@126.com; zhangdon...@gmail.com.

Dear Dong Zhang,

yes, actually it should be theoretically possible, we have discussed this while constructing the model but my opinion was that it is rather not applicable since we do not usually measure molecules with more than 3 isotopic signatures. Can you let me know what are you going to measure, why you need 5 isotopes? Are they from one singe compound (because only in that case such modelling would make sense).

regards,

Dominika
