APPLICATION NOTE

IARM-153C – Stainless Steel, Grade 317L

SUMMARY

This application note is for the digestion of IARM 153C, a grade 317L stainless steel.

Instrument:

ColdBlock CBM, ICP-MS, ICP-OES

Published:

November 2023

Digestion Time:

15 Minutes

Acid Used:Aqua Regia, HF
Average ColdBlock Recovery vs. CRM:
  • 99% Chromium

  • 98% Nickel

  • 99% Molybdenum

METHODOLOGY

  1. Chiller temperature was set to -5°C
  2. 0.25g of IARM 153C was weighed and placed into a ColdBlock HF friendly test tube
  3. 12mL of Aqua Regia + 1mL HF was added
  4. Sample was digested at 90% power for 15 minutes
  5. Sample was cooled and bulked to 50mL using 2% HNO3v/v

DISCUSSION

  • Samples were digested triplicate
  • After 15 minute digestion, the samples are green and clear
  • As a safer alternative to HF, you can add solid NH4HF2(Ammonium Bi-fluoride) or NH4F (Ammonium Fluoride)
  • IARM 153C is in the form of chips

IARM 153C after topping up to 50mL

IARM 153C- AISI 317L – UNS S31703 is a certified reference material (CRM) sourced from LGC ARMI. LGC ARMI, Analytical Reference Materials International, Manchester, New Hampshire, USA (October 2017)
