Teeth and bones micro-slurries introduction to MIP OES for elements simultaneous quantification

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

“…Janeda and Slachcinski devised a microvolume slurry nebulisation procedure for the determination of Ca, Cu, Fe, K, Mg, Mn, Na, Pb, Sr and Zn in teeth and bones by MIP-OES. 95 After removing any residual soft tissue with H 2 O 2 , teeth were ground in a ball mill with a tungsten carbide bowl for 2 min so that the material passed through a 32 μm nylon sieve. Slurries (3% m/v) were prepared from 150 mg of sample and 5 mL of water using an ultrasonic homogeniser with a microtip, and 15 μL of the slurry was injected into the microsampling device.…”
