A heated (approximately 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, N2, or gas mixtures (e.g., Ar-N2) from the electrospray source. Also, more concentrated organic solvents (e.g., 50% (v/v) methanol-water), typically introduced… CONTINUE READING
