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
Tech Overview - Low Pressure Liquid Chromatography
In our latest Tech Overviews article, we will discuss low-pressure liquid chromatography (LPLC) systems. Both types of chromatography separate components of a mixture by exploiting physical and chemical characteristics of the components present in the mixture. Like other types of chromatography, LPLC contains a mobile phase and a stationary phase.  Discuss
Tech Overview – Supercritical Fluid Chromatography
Supercritical fluid chromatography (SFC) is one of the few “green” purification technologies in the research space today. The method is unique in that a supercritical fluid is used as the mobile phase. This is a substance that has been both compressed and heated beyond its critical point, and thus a distinct liquid or gas phase does not exist; instead it is a supercritical fluid. The fluid is unique in that it has the high density of a liquid but the low viscosity of a gas. Read on to learn more!  Discuss
