 LGC ARMI announces the release of a new set of Nickel alloy Certified Reference Materials.

These include:

As always 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. 

 Want to learn more about thes reference materials ?  You can download the certificates of analysis using th hyperlinks above and check out our new products page for information on these and other recently released products.

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.

How to Prepare Metal Alloy Samples for Analysis by ICP-OES or ICP-MS

Metal alloys are commonly analyzed using solid sampling techniques such as Arc/spark optical emission spectroscopy (A/S OES), X-ray Fluorescence Spectroscopy (both Energy Dispersive (ED-XRF) and Wavelength Dispersive (WD-XRF)), and X-ray Diffraction (XRD). These techniques provide fast analysis with little or no sample preparation required, and can be provided as portable units, and in the case of XRF, hand-held units, for maximum flexibility. These techniques also are considered non-destructive in that the metal alloy is left largely unchanged after analysis, and is available for further testing or archiving.

Improve your ICP-OES Performance by using an Internal Standard

[fa icon="calendar'] Jun 2, 2017 12:40:33 PM / by Susan J. Evans Norris posted in Certified Reference Materials, metal alloys, ICP

[fa icon="comment"] 1 Comment

The use of an Internal Standard (IS) can significantly improve both the accuracy and precision of your ICP-OES analytical results. This post addresses:  how internal standards work, how to select an appropriate IS element, and how this methodology can be easily incorporated into your lab’s analytical procedures.

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.

What is Proficiency Testing ?

[fa icon="calendar'] May 4, 2017 8:00:00 AM / by Susan J. Evans Norris posted in Proficiency Testing

[fa icon="comment"] 3 Comments

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.

6 Things to Consider when Making Pressed Pellets for XRF Analysis

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.
