I will plan to measure Magnesium isotope in water and soil. Can anyone help me to find a relevant lab to measure Mg isotope and their sample requirement (sample quantity, preservative techniques, and soil sample pre-preparation method)
If you want to measure natural abundance ratios accurately then you will need to find a lab that has an an ion source and a multicollector MS. If you are spiking it should be possible to use conventional ICP-MS
