Aluminum reference materials are selected using several criteria: by grade, by major elements, or by concentration specifications. It can be a bit confusing to find the best reference material for your application. In this post, I’ll describe various types of aluminum reference materials and offer some suggestions on choosing the best option to meet your objectives.
Three Common Pitfalls to Avoid When Preparing Aqueous Multi-element Standards for AA, ICP, or ICP-MS
Generating high quality, accurate laboratory results starts with high quality, accurate standards. If your calibration standards are not correct, the analyses will not be accurate. Here are three common mistakes, and what you can do to avoid them, when preparing aqueous calibration standards for use in AA, ICP, or ICP-MS techniques.
Proficiency Testing is a key element in the laboratory accreditation process, alongside reference materials, enabling labs to monitor the quality of their analytical results. Proficiency testing determines the performance of individual laboratories for specific tests or measurements, and is used to evaluate laboratories’ continuing performance. PT is also called interlaboratory comparison.
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.
LGC ARMI is pleased to announce the release of two new standards, IARM 282A and IARM 4F.
These reference materials are available in three different forms depending on your analytical technique; 38mm diamater x 3mm thickness for XRF, 38mm diameter x 19mm thickness for arc spark OES or as chips for analysis by ICP or AA.

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.
