General Precautiona) This procedure is a reference point for sample digestion using a CEM system and may need to be modified or changed to obtain the required results on your sample.b) If using a vessel other than the recommended choice, adjust sample size and pressure limit to values appropriate for the vessel chosen.c) The control / reference vessel must contain the largest and most reactive sample.d) Manual venting of CEM vessels should be performed when wearing hand/eye/body protection and when the vessel contents are at or below room temperature to avoid the potential for chemical burns. Always point the vent hole away from the operator.e) If programming as One Touch, the ramp time and power will be automatically determined based on the number and type of vessels detected.

ResultsSample was clear, colorless, and particle free upon dilution to 50 mL.

NotesThis procedure can be used if it is necessary to complex the residual hydrofluoric acid or redissolve insoluble fluorides formed by reaction of certain analytes with hydrofluoric acid.

Alternatively, 1-4 g of solid H₃BO₃ + 25 mL deionized H₂O can be used in place of the 4% w/v solution.

ProcedureAllow vessel to cool. Add 30 mL H₃BO₃ (4%) into the vessel that contains the sample and acid.

NotesThe addition of Conc. HCl (0-4mL) is appropriate for the stabilization of Ag, Ba and Sb, and high concentrations of Fe and Al in solution. The amount of HCl will vary depending on the matrix and the concentration of the analytes. The addition of HCl may, however, limit the techniques or increase the difficulties of analysis.

ProcedureWeigh 0.5 g of the sample into the digestion vessel. Add 10 mL of HNO₃, or alternatively 9 mL HNO₃, and 1 mL of HCl. Gently swirl the mixture and wait approximately 15 minutes before closing the vessel.

This procedure can be found in the One Touch Method note entitled "Boric Acid HF Neutralization".

The addition of Conc. HCl (0-4 mL) is appropriate for the stabilization of Ag, Ba and Sb, and high concentrations of Fe and Al in solution. The amount of HCl will vary depending on the matrix and the concentration of the analytes.

ProcedureWeigh 0.1 g of the sample into the digestion vessel. Add 3 mL of HCl, 5 mL of HF, and 2 mL HNO₃. Gently swirl the mixture and wait approximately 15 minutes before closing the vessel.

General Precautiona) This procedure is a reference point for sample digestion using a CEM system and may need to be modified or changed to obtain therequired results on your sample.b) If using a vessel other than the recommended choice, adjust sample size and pressure limit to values appropriate for the vessel chosen.c) The control / reference vessel must contain the largest and most reactive sample.d) Manual venting of CEM vessels should be performed when wearing hand/eye/body protection and when the vessel contents are at orbelow room temperature to avoid the potential for chemical burns. Always point the vent hole away from the operator.e) If programming as One Touch, the ramp time and power will be automatically determined based on the number and type of vesselsdetected.

General Precautiona) This procedure is a reference point for sample digestion using a CEM system and may need to be modified or changed to obtain the required results on your sample.b) If using a vessel other than the recommended choice, adjust sample size and pressure limit to values appropriate for the vessel chosen.c) Manual venting of CEM vessels should be performed when wearing hand/eye/body protection and when the vessel contents are at or below room temperature to avoid the potential for chemical burns. Always point the vent hole away from the operator.

General Precautiona) If using HF, follow restrictions listed in HF Addendum.b) This procedure is a reference point for sample digestion using a CEM system and may need to be modified or changed to obtain the required results on your sample.c) If using a vessel other than the recommended choice, adjust sample size and pressure limit to values appropriate for the vessel chosen.d) Manual venting of CEM vessels should be performed when wearing hand/eye/body protection and when the vessel contents are at or below room temperature to avoid the potential for chemical burns. Always point the vent hole away from the operator.e) If programming as one touch, the ramp time and power will be automatically determined based on the number and type of vessels detected.

ReagentsHNO₃



NotesThe use of HF may be required to digest any silicates found in the sample. The addition of Conc. HCl (0-4 ml) is appropriate for the stabilization of Ag, Ba and Sb, and high concentrations of Fe and Al in solution. The amount of HCl will vary depending on the matrix and the concentration of the analytes. The addition of HCl may, however, limit the techniques or increase the difficulties of analysis.
