Tech Overview: X-Ray Fluorescence Spectroscopy
The focus of today's atomic spectroscopy series will be X-ray fluorescence spectroscopy, known as XRF. XRF provides analysis of the atomic composition of samples for a wide variety of applications. The technique is particularly well suited for analyzing the elemental range from sodium to uranium, covering the majority of the metallic elements. XRF can be adjusted in order to detect lighter elements. Many samples can be effectively examined non-destructively, though others will require grinding, fusion, or some other form of sample preparation, in order to ensure that the measurement reflects the bulk properties of the sample rather than the surface.  Discuss
The Intersection of Life Scientists and Social Media: A Revolution
How do your peers receive information online and how do they utilize social media as a means of learning new information and sharing content? These are just a few of the questions that our colleagues at BioInformatics Inc. explored in a recent report about digital marketing to life scientists.  Discuss
Precious Metal Analysis with Atomic Spectroscopy- A Touchstone for Today!
Human culture has valued gold since prehistoric times. Gold was used in trade, and the first gold coins arose in the 6th century BCE. Doubtless, counterfeiting and adulteration arose almost immediately thereafter. Consequently, technology arose to evaluate gold for authenticity and purity. The importance and ubiquity of these methods have led to them entering the language as metaphors – we may speak of an ‘acid test’ or ‘touchstone’ for evaluating or exemplifying something’s worth. Although few of us still use gold in a day-to-day fashion for commerce, the need to assess purity remains, and analytical laboratory tools can be brought to bear on the question.  Discuss
Role of Chromatography in Cannabis Testing
In our Global Assessment series, we’ve already covered many exciting technologies and topics, such as portable spectroscopy machines, NGS, Triple quadrupole ICP-MS, atomic spectroscopy, and their respective roles in the industry. Today our analyst, Ivan, will give us some insight into the role of chromatography in cannabis testing.  Discuss
Tech Overview - Arc/spark Optical Emission Spectrometry
Today we’re uncovering Optical emission spectroscopy (OES). OES is a general term for analytical methods that involve exciting a sample with energy so that the component atoms give off light radiation of particular frequencies that can be used to identify the composition of the sample.  Discuss
Tech Overview - Time of Flight Mass Spectrometry
If you have been following our mass spec series you have certainly recognized the number of different ways mass spec can be used to separate ions of different masses. Time of Flight Mass Spectrometry (TOF-MS) was developed in the 1940’s and began to gain popularity in the 1990’s. Since then, the technology has been enhanced and updated to be the device we have today.  Discuss
High Performance Liquid Chromatography: A Technical Perspective
We’ve already discussed how scientists use high-performance liquid chromatography (HPLC), and why it’s important during the process of making discoveries. Suppliers also have a significant role in this process, since they provide scientists with the tools they need. At The Science Advisory Board, our intention is to inform people about technologies like HPLC, including associated instruments, consumables, and services. Let’s take a quick look at a few of the techniques that are of notable interest to various scientific fields.  Discuss
Tech Overview - Magnetic Sector Mass Spectrometry
Magnetic sector mass spectrometry is the oldest and simplest of the mass spectrometry techniques. It makes use of combinations of magnetic and electric “sectors” that deflect sample ions as they pass through.  Discuss
Tech Overview - FT and Ion Trap Mass Spectrometry
In our latest post in the Mass Spec series we will discuss two great technologies: Fourier transform mass spectrometry (FT/MS)and Ion Trap LC/MS. FT/MS includes ion cyclotron resonance (ICR) designs and Orbitrap mass analyzers.  Discuss
Tech Overview - Flash Chromatography
Today’s focus will be on flash chromatography, a special type of column chromatography. Flash chromatography is a preparative liquid chromatography method that can quickly and easily separate organic compounds. This technique offers fast results because pressurized gas pushes the solvent through the column of the stationary phase, rather than rely on slower, gravity-based chromatography.  Discuss
