In GC analysis, chemical compounds are separated by their interaction with the stationary phase in a GC column. Sometimes, however, the separation is not sufficient to provide identification and/or quantification of all compounds. In many situations involving simple sample analysis, the inability to separate two compounds on a GC column with one stationary phase may be resolved by the use of a different column with a different stationary phase. However, as samples become more complex, the simple substitution of one chromatographic stationary phase for another may result in improvements in separation between some compounds with loss of separation between others. In this situation, the combined separation provided by each of two stationary phases is required. As opposed to limited techniques such as heart-cutting, comprehensive two-dimensional gas chromatography (GC×GC) provides superior chromatographic resolution across the entire sample.
In comprehensive two-dimensional gas chromatography (GC×GC) all of the analyte passes from the first column through the second. Compounds eluting from the first chromatographic column are trapped, and then systematically injected into the second column to obtain the second separation. In order to retain the chromatographic resolution obtained from the first separation, the second orthogonal separation must take place quickly. As such, it is important that compounds be introduced into this column quickly and in a narrow chromatographic band. In the LECO GCxGC system, this is accomplished by cryogenic dual-stage modulation. With cryogenic modulation, compounds eluting from the first chromatographic column are trapped in a narrow zone in the column as it passes through the modulator. When this zone is rapidly heated, the trapped compounds pass into the second chromatographic column as a narrow band, allowing for the highest possible resolution in the second separation.
LECO now offers . In order to properly trap and modulate analytes more volatile than n-octane (C8 n-alkane) the lowest achievable modulation temperatures are required. Reaching these low temperatures requires the use of a cryogen such as Liquid Nitrogen (LN2). LECO's LN2 modulator delivers the ability to modulate these volatile analytes. However, the use and management of LN2 dewars in a laboratory can be a hindrance to productivity. The Consumable-Free modulator is, therefore, an excellent choice for laboratories hesitant to take on the management of LN2 dewars and who do not require modulation of volatile analytes.

The Pegasus GC-HRT+ 4D provides the capability to obtain high-resolution mass spectral data using comprehensive two-dimensional gas chromatography (GC×GC). GC×GC provides high peak capacity by trapping compounds eluting from the first chromatographic column and then systematically injecting them into the second column to obtain the second separation. The separation on the second chromatographic phase is completed in seconds, resulting in very narrow chromatographic peaks (<200 milliseconds).
To obtain sufficient data to define a 2D chromatographic peak, acquisition rates of at least 100 spectra/second are required. With the Pegasus GC-HRT+ 4D, data acquisition rates of up to 200 spectra/second can be utilized, giving sufficient data density to obtain spectral deconvolution of the chromatographic peaks. Combined, LECO's GC×GC chromatography and the Pegasus GC-HRT+ provide the ultimate solution in complex sample characterization.

Comprehensive two-dimensional gas chromatography (GC×GC) is a technique that has been around for over 25 years. Some may argue that the technique has been over-hyped, and that it is a complicated research tool that doesn't fit into routine analytical laboratories. However, several routine validated GC×GC methods have demonstrated that the technique is accurate, precise, and robust. Research has shown the benefits of GC×GC in a wide variety of applications (e.g. environmental, metabolomics, petroleum, food safety, fragrance). The benefits include increased peak capacity (i.e. resolution), structured two-dimensional chromatograms (i.e. contour plots), and sensitivity enhancement. The merits of GC×GC as a separation science are clear, but how will it benefit a routine laboratory? Multiple analyte classes can be combined into a single analysis to save instrument and sample preparation time. Manual review time for non-target screening methods can be reduced with the increased peak resolution of a GC×GC analysis by creating a better library match leading to faster, more confident peak identification. Sample characterization is improved with a GC×GC analysis which increases confidence in decisions based on analytical results. The extra resolution afforded by the GC×GC analysis allows the use of more economical detectors, like the flame ionization detector (FID) or electron capture detector (ECD).

Mass spectrometers are perhaps the greatest tool available for the analytical chemist. With the ability to ionize, sort, and measure complex chemical mixtures by their mass-to-charge ratio (m/z) with femtogram (fg) to nanogram (ng) sensitivity, it is no wonder that mass spectrometers are widely used across many industries. The mass spectrometer can be divided into three main components: ionization source, mass analyzer, and detector. While the functions of the ionization source and detector are extremely important to the function of the mass spectrometer, it is the selection of the mass analyzer that can be tailored to meet data quality objectives. Sample matrix, required detection levels, target or non-target analysis, and budget all play an important role when selecting a mass analyzer. There are typically four types of mass analyzers to choose from: time-of-flight, quadrupole, ion trap and magnetic sector.
A time-of-flight mass spectrometer (TOFMS) is ideal for discovering new compounds in your sample, quantifying targeted compounds in complex samples, and increasing throughput with fast chromatography.
