  • A Synergy between Cryo-EM and NMR

    In this webinar, the aim is to explore molecular structures using Cryo-TEM, starting from a description of the Cryo-TEM technique and how it is used to investigate biological samples in order to scientifically contribute to protein studies. The webinar will also use application results to show how Cryo-TEM can provide synergy with NMR.
    Cryo-TEM is a high resolution imaging technique that is used to create 3 Dimensional reconstructions of biological protein structures down to the molecular level. These 3D reconstructions are used to visually verify the positions and configuration of molecules in the specimen and identify different conformational states of the proteins as provided in solution. These results readily provide the information required to complement NMR studies.

Mass Spectrometer (MS)

  • Exploring Chemical Constituents in Cannabis Using Nontargeted GC and GCxGC with TOFMS

    Cannabis is difficult to analyze because of its chemical diversity, but more importantly the wide concentration ranges of its constituents. This chemical diversity can be very important in determining its utility, potency and medicinal effectiveness. A powerful, nontargeted discovery technique—gas chromatography- and two-dimensional gas chromatography paired with time-of-flight mass spectrometry—was used to determine a wide range of constituents including cannabinoids, terpenes, terpenoids, noncannabinoid phenols, nitrogenous compounds, flavonoids, and contaminants such as residual solvents and pesticides.

  • GC-MS/MS Quantitative Analysis Solution for Pesticides Residues

    A high throughput GC-triple quadrupole mass spectrometer (JMS-TQ4000GC) has a capability of detecting 1000 different ions in a second during quantitative measurements.
    The high throughput is useful for measurements of pesticide residues where a large number of samples are handled. Fast GC conditions are known to reduce measurement time, however, they lead to a decrease in sensitivity. JMS-TQ4000GC achieves enough sensitivity and reproducibility even with Fast GC conditions because of patented short collision cell technologies. In this web seminar, we will introduce features of JMS-TQ4000GC based on the short collision cell and application of pesticide analysis. It will be shown that not only screening but also precise quantitative analysis can be done in 15 minutes with a Fast GC condition for around 300 pesticide residues in food samples.

  • How to get the most out of High-Resolution GC-MS

    Gas Chromatography-Mass Spectrometry (GC-MS) is widely used to separate compounds in complex mixtures, and analytes are typically identified through library database searches. This sounds like a very straightforward process in principle, but in practice compound identification can be complicated by having multiple high-scoring database matches or low-scoring matches for coeluting peaks. Furthermore, many compounds may not be registered in the database. Therefore, new analytical techniques are needed that make use of the information from high-resolution measurements and soft ionization methods. 
    In this presentation, we will discuss a new GC-MS analysis workflow that uses high resolution MS in combination with EI and soft ionization methods. The data interpretation software automatically generates a color-coded qualitative analysis report for all analytes present in the sample. The new workflow consists of chromatographic peak deconvolution followed by database matching, elemental composition determination for the molecular ion, isotope pattern matching, and EI fragment accurate mass analysis to identify the most likely candidate for compounds registered in the databases. This information can also facilitate the identification of compounds that are not in the database. A variety of samples will be presented to demonstrate the effectiveness of this new workflow.

  • GC-MS Qualitative Analysis Solution - How can we identify unknown compounds?

    Electron ionization (EI) is the most popular method used in gas chromatography-mass spectrometry (GC-MS).
    Because the molecular ions are often weak or absent in EI mass spectra, identification of unknowns can be difficult by EI alone. When this happens, soft ionization (SI) is helpful for obtaining and identifying the molecular ions.
    Recently we have developed an integrated qualitative analysis workflow to combine and interpret the information from EI and SI data. In this seminar, we will explain the integrated qualitative analysis workflow and its application which we have applied this workflow to polymer samples in order to evaluate known and un-known compound analysis.

  • Advances in Liquid Nitrogen Cold Probe Technology

    Cold probe technology offers significant sensitivity enhancements over traditional room temperature probes. Using liquid nitrogen as the cryogen affords greatly reduced operational costs compared to Helium cryostat probes. Another excellent choice with low running costs and slightly better performance is a closed cycle Helium cooler running at 50 kelvin. Basically by reducing thermal noise these probes can reduce experiment time by a factor of about 9 with no loss of experiment flexibility.
    Examples of very modern 1 and 2 dimensional NMR data acquired with a fully broadband nitrogen cooled probe will be presented and by example illustrate robust approaches to solving common difficult and interesting strucure problems. Measurements tradiionally difficult to access such as carbon-carbon direct and long-range coupling pathways and J values, now very useful in computational chemistry, are shown to be easily accessible by simple 1 dimensional experiments.

  • An Introduction to Pure Shift NMR

    NMR is an enormously powerful analytical technique, yielding unrivalled insights into the chemical structure and dynamics of organic molecules. Unfortunately, the information that can be readily extracted from the NMR spectrum is sometimes limited by overlap between neighboring peaks, a problem which is often exacerbated by the presence of broad peak “multiplets” due to J-splittings. This is particularly a problem in proton spectra, where the narrow chemical shift range and manifold J-couplings between protons can lead to severe peak overlap. In recent years, much work has been done to develop NMR methods that yield spectra where the peak multiplet structure is completely suppressed; these so-called “pure shift” spectra show much higher resolution than conventional spectra. In this short webinar, we introduce the basic principles of pure shift NMR and describe some of the most popular and important pure shift methods that have been developed to date.

  • Core principles of precise qNMR – Common Pitfalls and Solutions

    A modern NMR spectrometer has the exquisite property that the data is inherently quantitative. By following a few experimental guidelines, good accuracy and precision are routinely obtainable. Though quantification by NMR is most commonly done using proton, in principal many spin ½ nuclei could also be used. A unique aspect of quantification using NMR is that typically no chemistry needs to be done up front on the molecule and response factors do not need to be cataloged – Simply put the analyte into solution and record the results. Therefore, qNMR is a non-destructive analytical technique.
    The approach to quantitative analysis with qNMR data depends upon how precise an answer is needed. Experimental details also become more critical as higher sub-percent accuracy is required. If an accuracy of a few percent are sufficient for the problem at hand not much is needed except a routine spectrum and a result from a similar sample of know concentration as an external reference. There are many software tools to allow results for either traditional integration or direct time-domain amplitude extraction such as CRAFT which virtually eliminate operator bias or skill from the all-important data analysis part or the qNMR process.

  • Elucidating nano-crystalline structure by combining microED and solid-state NMR

    In this webinar, we will introduce a novel method to solve a crystalline structure from nano- to micro-sized crystals. Quite recently, microED is introduced to solve the structure from such a tiny single crystal. Although microED is a very powerful technique, the structure solved by microED is not perfect especially atomic resolution structures. For example, microED often mis-assign atoms with close atomic numbers (like carbon, nitrogen and oxygen) and more importantly locates hydrogen poorly. On the other hand, solid-state NMR is very sensitive technic to probe a local structure. Solid-state NMR has a very high capability to resolve nuclei, and directly monitor 1H. In this regard, information from microED and solid-state NMR provide complementary. We will demonstrate the combined method of microED and solid-state NMR on a small amino acid and small pharmaceutical molecule whose structure has not been solved. We will also introduce a toolbox for pharmaceutical applications.
