Texray Laboratory Services provides XRD and WDXRF based analysis services including corrosion analysis, quantitative and qualitative material composition analysis, mineralogical (geological) analysis, industrial hygiene measurements and many other advanced XRD techniques (non-ambient temperature and

Energy resolution 140eV under ideal conditions. All KB peaks eliminated electronically. W LA1 (8.40 KeV) lines eliminated from Cu KA1,2 (8.04 KeV) scans even with thoroughly contaminated tubes. Common fluorescence energies (i.e. Fe when Cu tube anodes are used) are greatly reduced. (Brehmstralung ef

KS Analytical Systems now offers custom sample holders for Rigaku Miniflex systems. The 6-position autosamplers and rotation stages (and even some fixed stages) make use of the magnetic disk design for holding powder without taking up much extra room in the diminutive benchtop. Top-loading Rear-load

Another fully-rebuilt, digital autosampler out in the wild. This one is on a system that already has one of our Si-Drift Detectors and an awesome ICDD Jade Pro/PDF-4+ software package. We've got all the fancy new hardware at our in-house lab, but when we need the absolute best data, this is our goto

KS Analytical Systems now offers custom sample holders for the Bruker D2 Phaser 6-position autosampler. These can be finished to order with any depth and diameter of well or a zero-background plate (ZBH) with or without a well ground in the surface.

We've been experimenting with better ways to quantify the quality of XRD tubes in the shop. We use these tests on new and used tubes to monitor performance in two key areas. 1) Intensity 2) Spectral purity. What we've settled on is a test that involves a wavelength-dispersive approach which gives us

Plastic sample holders have been the default option XRD for decades. They're inexpensive to make, good enough for most purposes, and very resistant to a wide range of chemicals. Seems like a "win" all around right? As long as they're made correctly and from the proper materials, these work just fine

Curiosity may have killed the cat, but it's the lifeblood of a well-functioning analytical lab. A few days ago, Todd was preparing a water chiller for shipping and washed out some corrosion products with acetic acid. The resulting solution was left in a beaker over the weekend and when we returned,

XRD tubes rely on the ability to precisely regulate the flow of electrons from the filament to the anode in order to create x-ray emissions. That requires a completely evacuated envelope to avoid having the high-voltage short to ground. The resulting symptom is that the high voltage generator will s

It's easy to forget how much of our scientific work hinges upon comparative data. The entire field of metrology is concerned with the verification and maintenance of "standard reference materials" (SRMs). Creating a perfect reference standard essentially involves proving a negative. In the XRD world

There's a simple and inverse relationship between the average atomic number of a given matrix and the efficiency with which it scatters X-rays. The effect isn't all that much different from shining a flashlight on a white piece of paper. While it's nothing like a mirror, you'll definitely get light

The D4 Endeavor fits in a unique niche in the XRD world. It's basically the same thing as a Bruker D8, but built into a very compact cabinet with a large autosampler on top. These machines see heavy use in the cement, pharmaceuticals, and aluminum industries among others. Today we have one headed ou

Your little scientist will love the realistic lights and sounds of their very own X-ray diffraction system. At KSA we are firm believers that kids learn best by "doing". There's no better way to bring the next generation of bright thinkers into the lab. Now they can analyze real materials just like

This project started with a phone call several months ago from a Canadian government lab. They had a very specific application so the design was driven much more by their requirements than most zero-background holder designs. A 1mm deep well with a zero-background plate at the bottom was a key speci

Much of the material we receive is already finely ground and ready for XRD or XRF analysis, but sometimes we receive bulk material which must be homogenized before we can take a representative split for analysis. This is one of the most frustrating parts of working with samples and very time-consumi

The Siemens D5000 and Bruker D8 systems we work with have an optional phi-stage that is very useful. It looks and moves like any other rotation stage, but it's driven by a stepper motor which actually makes it an additional degree of freedom. The user can rotate the sample at a specified rate, posit

X-Ray Diffraction (XRD) systems analyze the structure of materials such as crystals and powders. The X-Ray Tube generates heat from the interaction of electrons in the cathode and the anode. The electrons emitted from the cathode (filament) are accelerated towards the anode – when the electrons hit

KS Analytical Systems is proud to present a new, total UPS solution for clinical and diagnostic laboratory systems, specifically designed for Bruker AXS, by NXT Power. The Integrity Max & Pro UPS is a complete power protection solution providing isolation, power conditioning, and backup protection f

These are probably the smallest parts we make in-house, but they're critical to the proper function of about half of the instruments we support. These little bushings support the impeller of the water flow sensor in many Siemens and some Bruker XRF and XRD machines. They last for several years in mo

Revisiting an experiment from 2014 I still reference this post on our laboratory site often so it seems like it deserves a place on the main blog for KS Analytical Systems. Enjoy Our recent sealed sample cell project required a thin covering film to be applied over loose powder before analysis by XR

One of the fundamental facts of lab-based X-ray production is that our x-ray tubes emit much more than the pure KA1 lines we rely on for material characterization and quantification. Most XRD users are familiar with techniques and hardware for the reduction or elimination of KB1, W LA1 and Bremsstra
