New ARMI Reference Materials

Developing new reference materials can be a time consuming process often requiring several years to complete. This means that reference material development typically lags well behind the introduction new metal alloys created to meet the needs of  increasingly demanding industrial applications. This disparity creates a problem for chemists working with analytical methods such as XRF, ICP and OE, as these are comparative techniques and require reference materials to calibrate and validate.

How to Digest 316 Stainless Steel for ICP Analysis Using the ColdBlock Digestion System

[fa icon="calendar'] Jan 30, 2018 5:40:25 PM / by Dave Coler posted in stainless steel alloys, icp sample preparation

[fa icon="comment"] 3 Comments

 

The ColdBlock system uses infrared radiation to rapidly digest metal alloy samples and a cooling block to condense out escaping vapors minimizing the loss of volatile elements.  Our preliminary results, detailed in a previous blog post (A New Sample Preparation Technique for  Metal Alloys), looked promising so we are now conducting validation studies with IARM CRM’s of various alloys.  This post details our validation study using CRM IARM 5I, a Grade 316 stainless steel alloy.

Digestion Procedure

5 separate 0.5g aliquots of CRM IARM 5I were prepared using 20ml of aqua regia in a quartz digestion tube.  The 5 digestion vessels were loaded into a 6 position ColdBlock digestion system and digested for 15 minutes at 28% power.  The digested samples were diluted to a total volume of 50ml using deionized water and transferred to a centrifuge tube.  1 ml of HF was then added to each centrifuge tube to stabilize the solution. The samples were then analyzed on a Spectro Arcos ICP-OES in our laboratory.  The results are detailed below.  The reproducibility of each of the 5 digestions is very good, and the average values agree well with the certified values for all elements including Si and volatile elements such as As and S.     We will be posting the resuts of  validation studies on other alloys in the near future so subscribe to our blog to be sure you are automatically notified.
