Fast determination of electrolyte elements in human blood plasma using surface-enhanced laser-induced breakdown spectroscopy combined with a gel film method

Abstract

Electrolyte elements in human blood plasma play an important role in maintaining the osmotic pressure and acid-base balance of body fluids. Rapid and accurate detection of electrolyte concentrations in blood...

Atomic spectrometry update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…The paper provided a robust assessment of the approach which achieved accurate results from 10 μL of serum with RSDs of <6% for Na and <4% for K and R 2 exceeding 0.98 with analysis times under 5 min. Another group 145 took a slightly different approach by employing surface enhancement to improve sensitivity. Blood plasma was dropped onto a metal substrate, allowed to dry and coagulate into a gel then into a solid state.…”
