Hi Bruker I watched this video and you have explained it nicely and I have a small question can we obtain better results with xrf for biological samples and what is your opinion about icpms and your product on biological sample analysis?
Greetings and thank you for your interest in our channel! If you would like to obtain “better results with xrf for biological samples” we would first need to know “better than what?” The systems shown here are for bulk elemental analysis, so if you have a bulk sample, like a liquid, or finely ground powder of a sample (for an example for biomatter: dried plants) you can measure it with our systems. With the right standards you can set up a calibration which can easily measure single digit ppm values for most elements. With standardless applications, the sample preparation and giving the evaluation algorithm the most information you can is important to get to levels between 10-100 ppm for most elements If you are looking for measuring light elements, like H - O, please know that that is not possible in general for ED-XRF. For WD-XRF we can measure down to Be, but measuring elements lighter than Na or F is a challenge for all XRF systems, because these elements do not fluoresce much. If these light elements are what you are interested in for your biological applications, you might be better off with IR or other technologies. In comparison to ICP-MS, XRF is almost equally good. No, we do not get to ppb levels, but on the other hand we also do not need to dilute the samples by a factor of 1000. As far as I know ICP-MS cannot measure light elements at all, cannot measure Na well, and cannot measure halides, which are both no problem for XRF. If you want to discuss this in more detail, please reach out to info.baxs@bruker.com.
Hi Vivek. Thanks for your question. The S8 Tiger can detect elements from Boron up, but special crystals and collimators are needed, the measurement mode must be vacuum and the samples must be prepared in a very reproducible and homogeneous way and be flat. For the S6 Jaguar, elements below Na ( or F if using vacuum mode in certain cases) are not practical, because only one collimator position is available, and because lighter elements fluoresce less, so a higher power instrument is needed. If you want to measure light elements via XRF the S8 Tiger is the only option. Depending on the sample type and the concentrations, a different technique like CGA would be suited better.
@@Bruker We want to measure lighter elements, specially carbon contents in Fe and Al Alloys. Which model is suitable for that, it can be any technology?
The result of a WD-XRF (wavelength dispersive x-ray fluorescence) measurement is fluorescent intensity. This can either be just at a fixed angular position (which corresponds to an energy) used for calibrations or over a larger angle range which results into a spectrum. In general, we refer to them as results as well and each element is usually reported as ppm or wt %, however custom units can be set up. We build a calibration using Certified and/or Secondary Standards and run unknown samples against the calibration for each element. If you do not have calibration standards then we can run the unknown samples against our standardless program that will also show the spectrum of the sample and help you identify which elements are present in your sample. You can reach out to your local Bruker Office to obtain more information.

Hello
The tiger spectrometer S8 it is no need to use a sofware ?
Greetings! The software is built into the system and accessed via the integrated touch screen.
Can it detect Carbon Compositions? And Lower Element Composition?

The G4 Icarus which is part of our CGA group will be able to detect C in Fe & Al Alloys
hello, may i ask whats the result of wdxrf called? is it just wdxrf spectrum? thank youu

@@Bruker thank youu so much for your answer, it helps me a lot
