The helium supply chain crisis has negative implicationson research and laboratory operations world-wide. Helium rationing, delayed deliveries and price increases still cause difficulty in production planning and uncertainty in instrument productive uptime.
Although the GC & GC-MS segment consumes less than one percent of the global helium supply usage per year, the shortages and delivery interruptions have wide-spread consequences for many industries utilizing varied analytical techniques.
There are different way to tackle this problem, one is reducing the split ratio during the split time of the injection or switch to another carrier gas such as hydrogen or switch gas only when the GC or GC/MS are not running.
The Thermo Scientific™ Instant Connect Helium Saver Injector Module allows to massively reduce the helium consumption while working as an usual Split Splitless injector. The Helium saver module benefits from the modularity concept of all of the injectors and detectors for the Thermo Scientific™ TRACE™ 1300 Series GC and can be quickly installed and operative maximizing instrument uptime. The Helium Saver module can be mounted also on pre-existing TRACE 1300 Series GC systems without modifications.
Nitrogen metabolism in Mycobacterium tuberculosis: a systems-based approachPoster
Previous studies suggested that Mycobacterium tuberculosis obtains nitrogen from a diverse range of intracellular nutrients including amino acids. Here, we use a novel system’s based three-pronged approach to define pathways for uptake and assimilation of nitrogen.READ MORE

Using Elemental Analysis For Discrimination Of Pinot Noir Wines From Six Different Districts In An AvaPoster
The determination of geographical origin of wine is gaining increased interest by researchers and federal agencies around the world, partially due to increased fraud with regards to place of origin labelling. For wine, multi-elemental profiling of macro, micro, and trace elements has been proposed for determination of authenticity. Commercial wines from different wineries in 5 different neighborhoods within one AVA show characteristic elemental fingerprints. Macro, micro and trace elements as well as elemental ratios contribute to the observed separation, indicating the involvement of multiple factors and underlying mechanisms, including location and soil composition, elemental uptake by vine and rootstock, viticulture and nutrient management, water sources, and small differences in the different wineries.READ MORE
