Digestion System (See pg. 41), sulfuric
Product Type Cartridge (5 / pk) Powder (10 g) acid can digest almost any organic matrix.
Catalog No. Catalog No. However, it is extremely viscous, even at low
DigiSEP AN-01 concentrations, and requires long washout
DigiSEP AN-02 010-720-001 010-790-001 times through the ICP spray chamber. The
DigiSEP Ha-01 010-720-003 010-790-003 AN-01 cartridge will avoid this problem.
DigiSEP F-01 010-720-005 010-790-005
DigiSEP F-02 010-720-007 010-790-007 At present, the only way to digest SiO2
010-720-009 010-790-009 is to use an excess of HF (hydrofluoric
acid) which creates problems with ICP
spectroscopy. The resulting F- excess can
precipitate elements of interest such as
Mg and Al. In the past, Boric Acid has been
added to the remaining F- ion complex.
However, this solution results in a more
complex matrix increasing the analytical
difficulty. Now with the DigiSEP F-01 and
F-02 cartridges, the excess F- ions can be
removed.
