The GC-2010 Plus enables reliable, high-precision trace analysis with outstanding repeatability, utilizing the full suite of detectors that feature best-in-class sensitivity.
Rapid oven cooling, high performance flow control and backflush technology allow the user to shorten analysis times greatly for significant gains in productivity. The full line-up of GC detectors has sensitivity specifications that are among the highest in the industry, ensuring quality data across a broad range of applications.
The high-sensitivity of our detectors was achieved by thorough cleaning of detector gas lines , with the incorporation of the highest quality electronic components and implementation of the latest electronic noise-reduction technology.
Safety First when it comes to using Hydrogen Carrier Gas
The Automatic ignition, re-ignition, and flame extinguishing functions allows the user to have complete electronic control of the detector combustion gases. The detector signal feedback function allows the GC to cut the gas supply pressure to zero when the hydrogen flame is extinguished. Hydrogen supply fittings have reverse threads to help prevent incorrect plumbing connections. The full complement of GC inlets are equipped with electronic flow controllers that will turn themselves off if they sense a leak resulting in a pressure drop. These combined features allow the end user the confidence and assurance that the GC 2010Plus is ready to be safely operated when using Hydrogen carrier gas.
A multi-dimensional GC/GCMS system performs separations using two columns that have different chromatographic selectivity. When components of interest are insufficiently separated on the first column, they can be selectively introduced ("heart-cut") to a second chromatographic column with different selectivity. This enables enhanced chromatographic separation that cannot be attained in conventional single-column analysis. In addition, the precise flow-switching technology, which is supported by a high-precision digital flow controller, ensures heart-cut analysis with the high level of reproducibility demanded of complex capillary GC separations.
In the past, multidimensional GC has been accomplished using a switching mechanism known as Deans’ Switch. However, this system results in such problems as a reduced recovery (sample loss) and fluctuations in retention time after column switching. The MDGC/GCMS-2010 system incorporates multi-Deans switching, a new mechanism that significantly reduces the likelihood of fluctuations in the retention times of components eluted after column switching, even when column switching is performed several times.
The backflush system reverses the carrier gas flow after the target compounds have eluted, to discharge residual late eluting components in the column through the injection port split vent. Backflush shortens the analysis time and improves productivity. In addition, high-boiling point components are discharged efficiently to reduce the bakeout time (elution time), and thus prevent column deterioration, contamination, and retention time shifts.
A new FPD design featuring improved flame stability and double focusing optics has produced an FPD with the world’s highest sensitivity. This has all been achieved in a compact design that fits within the detector bay. The dual-focus system adds a lens to the interference filter for efficient light collection at the photomultiplier light receptor.
