Chemical Stability and Compatibility - Interactive Periodic Table stability data

The long term stability of single or multi-element solutions is a function of several factors, and the Interactive Periodic Table data you reference represents a broad set of various studies that attempted to characterize chemical stability. A more detailed study that focused on multi-element mixtures is the Part-Per-Billion Stability Study on our website (https://www.inorganicventures.com/part-billion-stability-study), which represents 65 elements combined at 2, 10, and 100 ppb. Regardless of the actual dataset, the periodic table and ppb stability study are intended to provide general guidelines, and we would be cautious about assigning exact timeframes to the chemical stability of any given element. One important factor is the cleanliness of the container; the LDPE bottle leaching described in the ppb stability study is critical for the stability of these mixtures. Slight variations in the trace HCl and trace HF acid concentrations could also significantly affect the stability of some elements. Our recommendation is that the data presented be taken as a whole, with the understanding that several factors (e.g., individual elements, container materials, storage conditions, exact matrix compositions, etc.) could have significant effects upon long term chemical stability.
