METHODOLOGY

Chiller temperature was set to -5°C
0.25g of IARM 153C was weighed and placed into a ColdBlock HF friendly test tube
12mL of Aqua Regia + 1mL HF was added
Sample was digested at 90% power for 15 minutes
Sample was cooled and bulked to 50mL using 2% HNO3_v/v

DISCUSSION

Samples were digested triplicate
After 15 minute digestion, the samples are green and clear
As a safer alternative to HF, you can add solid NH4HF2(Ammonium Bi-fluoride) or NH₄F (Ammonium Fluoride)
IARM 153C is in the form of chips
