Kevex XRF Deserves a Closer Look. per million (or even parts per billion in organic matrices) to one hundred percent. XRF looks at innershell atomic structure, so the state of the sample is not important. That means virtually no sample preparation is necessary. Samples can include solids, liquids, powders, aerosols and small particles. And all analyses are nondestructive.
There are a lot of ways to perform quantitative elemental analysis, and you're probably familiar with most of them. Atomic absorption, wet chemistry arc and spark emission are all standard analytical resources. A more recent development, ICP, is another alternative. Energy-Dispersive X-Ray Fluorescence Kevex would like you to take a closer look at one more possibility: energy-dispersive x-ray fluorescence. Because while all these methods perform similar analytical functions, XRF has some outstanding advantages. Fast, Multi-element Analysis X-ray fluorescence simultaneously detects all elements heavier than fluorine, allowing complete qualitative and quantitative analysis in a single run. By using multiple-element secondary
targets, you can optimize detection limits for several elements at once, when critical results are sought. And analyses typically last only a few minutes. A Broad Dynamic Range Because XRF isn't vulnerable to many of the interferences that plague AA and ICE you can use it to determine elemental concentrations from a few parts
So give Kevex a closer look. We've already installed close to 200 systems in laboratories worldwide, analyzing samples as diverse as metals, ores and petroleum products, industrial chemicals and waste, aerosols, ceramics, forensic samples, food, pharmaceuticals and semiconductor wafers. Kevex XRF may be the right alternative for you, too. Contact Kevex today for literature and applications information.
