Kidney stones analysis by ICP-OES

Journal of Physics: Conference Series, 2020
Abstract The elemental composition of 100 oxalate type (only whewellite, weddellite and their mixture) urinary stones was determined by ICP OES. The calcium content varies from 130 to 320 g/kg; phosphorus – from 1.6 to 28 g/kg; sodium – from 0.54 to 8.7 g/kg; Ba, Fe, K, Li, Mg, Sr and Zn – from 0.0002 to 2.0 g/kg.

Using ICP-OES and SEM-EDX in biosorption studies [PDF]

Microchimica Acta, 2010
We have compared the analytical results obtained by inductively coupled plasma optical emission spectroscopy (ICP-OES) and by scanning electron microscopy with an energy dispersive X-ray analytical system (SEM-EDX) in order to explore the mechanism of metal ions biosorption by biomass using two independent methods. The marine macroalga Enteromorpha sp.

A comparison of two methods for determining titanium dioxide marker content in broiler digestibility studies

Animal, 2014
The use of inert markers in broiler diets eliminates the need to quantitatively evaluate feed intake and excreta output to determine diet digestibility, and enables nutrient uptake at specific points along the gastrointestinal tract to be examined ...
