ICP-MS Ultra High Matrix Introduction (UHMI)
UHMI, included with the 7850, 7900 and 8900 ICP-MS systems, is a sample dilution technique, but because it uses clean argon as the diluent, it completely eliminates the potential problems of liquid dilution, including increased risk of sample contamination, leaks in tubing connections, dilution errors, waste disposal costs, and sample prep time.
