Micrograms of platinum,palladium and iridium were employed for stabilizing trace arsenic,selenium,tellurium,silver,antimony and bismuth.Tolerated charring temperatures for those elements can bo raised up to the range of 1000 to 1500℃ with significant improvement of sensitivities.Mechanism of stabilization effect was poytulaced to be the formation of stable compounds or alloy.
