Abstract: 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.
Summary: We introduce a new, innovative injector which allows conservation of helium carrier gas. While preserving the analytical GC column flow with helium, it maintains the septum purge and the split flows with another inert gas like nitrogen - even during the analytical run. The analytical performances of the injector are in line with those of the common split/splitless injector moduleReport abuse »
