7:4 Stability of elements at ppb concentra'on levels

Desorp'on of adsorbed inorganic anions - A3empts to remove adsorbed ions typically require extreme condi'ons and are only par'ally successful, as seen below.

7:5 Stability of elements at ppb concentra5on levels

Preven&on of adsorp&on by complexa&on - A6empts have been made to prevent adsorp&on by complex forma&on, as shown below, but the use of rela&vely high levels of reagents increases the risk of contamina&on. Furthermore, it tends to influence the stability and chemistry of other analytes of interest.
