New Steel Certified Reference Materials

[fa icon="calendar'] Nov 7, 2017 10:38:12 AM / by Dave Coler posted in carbon steel, low alloy steel, metal CRMs

[fa icon="comment"] 0 Comments

ARMI is pleased to announce the release of 5 new steel certified reference materials.  These new reference materials include 5 low alloy steels; AISI grades 4140, 4330, 4340, E52100 and 5Cr ½Mo.

As always these reference materials are available in three different forms depending on your analytical technique; 38mm diameter x 3mm thickness for XRF, 38mm diameter x 19mm thickness for arc spark OES or as chips for analysis by ICP or AA.  

The complete listing of the new reference materials are shown in the table below along with links to the certificates of analysis.  You can also check out our new products page to see all of our latest CRM's.

Evaluation of a New Sample Preparation Technique for Metal Alloys

In a previous blog post “How to prepare metal alloy samples for analysis by ICP-OES or ICP-MS”, my colleague Sue Evans Norris described the traditional methods for metal alloy sample preparation.  At ARMI, we are always looking for ways to improve the status quo and recently discovered a new sample preparation technology for the rapid digestion of metal alloys using short-wave infrared radiation.  This technology, promoted by a Canadian company called ColdBlock, claims their instrument can digest metal alloys faster than current techniques while eliminating the need for dangerous acids such as hydrofluoric and perchloric acid.

Set Up Samples (SUS)

 Set up Samples were described in a previous blog post by Charlie Hodges entitled “How to Choose the Correct Aluminum Reference Material for Your Application” but in general, they are homogeneous reference materials used for daily drift correction or standardization or slope correction, typically for arc spark optical emission spectroscopy.  These materials are homogeneous and are usually provided with a certificate of analysis showing the approximate chemical composition but differ from a certified reference material in that there is no supporting statistical data.   These types of materials offer a low cost alternative to consuming expensive CRM’s for daily drift correction.

Introduction

XRF (X-ray Fluorescence Spectrometry) is a chemical analysis tool commonly used for the quality control of raw materials and finished products in many industries including cement, mining and industrial minerals.  The capabilities of XRF instrumentation have advanced significantly in the past decade in both sensitivity and stability such that they are no longer the most important source of error in an analysis.  Sample preparation is now by far the most significant source of error in the analysis of materials by XRF.  Viewed from this perspective, it is clear that high quality sample preparation techniques and practices are the key to achieving consistent and reliable analytical results.

Top 5 XRF Reference Textbooks

XRF or X-Ray Fluorescence spectrometry is an elegant chemical analysis technique used frequently in many industries for quality control of materials and R&D.  Despite its widespread use in industry, it is an analytical technique rarely encountered by students in colleges and universities, especially in the United States.   The rare exceptions to this are the geology departments in a few institutions where the technique is still used for geochemical studies.
