* Note:
Hydrofluoric acid reacts slightly with sapphire resulting in mildly elevated aluminum values. To reduce
these values we recommend discarding 3-5 dispensings of 2 ml each before performing the analysis.
Compounds containing fluorine, such as NaF, attack tantalum.
The above recommendations reflect testing completed prior to publication. Always follow instructions in the
operating manual of the instrument as well as the reagent manufacturer's specifications. In addition to these
chemicals, a variety of organic and inorganic saline solutions (e.g., biological buffers), biological detergents
and media for cell culture can be dispensed. Please call us if you need information on chemicals that are not
