Interference-free determination of arsenic in urine by atomic absorption using two-stage probe atomization in a graphite furnace

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

“…In this latest review period, two groups have published work using an atomiser based on similar principles. Using a system designed in 2015 by Zakharov, Irisov et al 84 described the measurement of As in urine which avoided lengthy sample preparation. Sample and modifier were placed into a graphite furnace in a HR-CS-AA spectrometer.…”
