The mineral content of the medical herbs was determined with a Prodigy High Dispersive ICP spectrometer (Teledyne Leeman, Hudson, NH, USA) working in a simultaneous mode. The spectrometer is equipped with a high resolution Echelle polychromator and a large format programmable array detector (L-PAD), RF-Generator (40 MHz “free-running”, output power 1.1 kW), a peristaltic pump (sample uptake flow 1.0 mL/min), a pneumatic nebulizer, and a glass cyclonic spray chamber. Measurements were run with optimal argon flows (coolant: 18 L/min, auxiliary: 0.8 L/min, axial plasma viewing, a sample uptake delay of 30 s and 3 replicates.
