Pure KA1 XRD with the Johansson monochromator

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 Bremsstrahlung, but take for granted the inseparable pair of KA1 and KA2 (referred to as the “doublet”). Luckily for us, these energies are present in strict proportion such that we can factor their paired presence into

Plastic barrier film for air-sensitive sample holders

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 XRD. We tested a few options for this film as part of the design process and the results were interesting enough that we thought it would be worth dedicating a full post

Small, but not insignificant

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 most cases, but we replace them during most PM service visits because they’re easy to keep on-hand and very inexpensive. This is a great example of a part that would

The Ultimate Power Protection Solution: UPS Designs for Bruker AXS Systems by NXT Power

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 for Bruker AXS systems. Regardless of input fluctuations, the Integrity series ensures that the output remains continuous and regulated. The industry-leading UPS line is built to power sophisticated computer loads–systems with high inrush

Water Flow and Cooling Performance – The Lifeline of a Healthy XRD System

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 the anode, they produce x-rays. Keep in mind that the focal “spot” on the anode is most commonly only 12×0.4mm rectangular. The full power of the generator is being dissipated

Filter membrane sample holders for Rotation/Phi stages

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, position it at a specified angle, or even perform a scan in the phi axis. We have a client who just took delivery of their D5000 and

New orbital crusher

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-consuming as we’ve historically done it by hand. This usually means splitting out a large fraction of the material and breaking up larger rocks, etc by hand, sieving, then breaking

Rigaku D-Max zero background sample holders

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 specification. We tried several options for creating this, but settled on a two-part design with a solid “floor” plate and a ring above it. As it turns out, cutting a

Introducing the KSA “My First” XRD system

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 Mom and Dad!
