Oxide – Quartz	Fusion	Fuse in Pt crucible with Na₂CO₃
Geological Samples	Fusion + acid dissolution	Fuse in Pt crucible with Na₂CO₃, dissolve fuseate in HCl
Organic Matrices (silicates / non-volatiles)	Ashing + acid dissolution or fusion	- Dry ash at 450°C in Pt crucible, gently warm with 1:1:1 H₂O / HF / H₂SO₄ - Or fuse/ash with Na₂CO₃, dissolve fuseate with HCl / H₂O
Silicone Oils	Alkaline or oxidative breakdown + dissolution	- Avoid direct organic analysis (leads to false highs from volatile monomers) - Preferred: React with alcoholic KOH/xylene at 60–100°C to depolymerize - Alternative: Digest with conc. H₂SO₄ / H₂O₂, cool, then dissolve dehydrated silica with HF - KOH forms non-volatile K₂⁺Si(CH₃)₂O⁻NaCl, allowing accurate analysis

Elemental Iodine (I₂)	Controlled oxidation or alkaline dissolution	- Volatile and easily lost during heating or open digestions - Dissolve in alkaline iodide (e.g., NaOH + NaI) to stabilize as I⁻ - Avoid acidic conditions unless using a closed system
Oxides & Iodates	Acid or reductive dissolution	- Soluble in dilute HCl or reducing agents (e.g., thiosulfate for IO₃⁻)
Ores / Minerals	Alkaline fusion or reductive leaching	- Use Na₂CO₃ / NaOH fusion in Pt or Ni crucible for insoluble iodides - Alternatively, leach with NaHSO₃ or Na₂S₂O₃ under reducing conditions
Organic Matrices	Mild alkaline digestion or combustion	- Dry ash avoided due to I₂ volatility
Special Notes	Volatility	- I₂ is volatile and can be lost during ashing, heating, or acidic digestion - Closed-vessel digestion or alkaline stabilization strongly recommended
