According to recent research from the United States, "A heated (approximate to 90 degrees C) laminar flow interface has been designed to assist in the development of an argon electrospray sample introduction system for low-flow rate applications using inductively coupled plasma (ICP) spectrometry. Previously, the stability and robustness of the ICP were compromised by the entrainment of air, N-2, or gas mixtures (e.g., Ar-N-2) from the electrospray source."
"Also, more concentrated organic solvents (e.g., 50% (v/v) methanol-water), typically introduced by electrospray, could generate carbon. deposits that obstruct the entrance lens to an ICP optical emission ...
