Our thermal modulation system, the QuadJet™, is recognised as the gold standard in GC×GC modulation, providing the highest sensitivity available on the market - ideal for analysing the most complex samples.

One of the main advantages of LECO’s GC×GC-TOFMS is its ability to provide vastly improved peak capacity and resolution than traditional GC-MS systems. It also offers comprehensive information about the sample by separating compounds based on two different properties (volatility and polarity). Combining GC×GC with TOFMS is an ultimate solution for the analysis of complex samples.

This high-resolution mass spectrometer features industry leading mass accuracy, full mass range acquisition with exceptional speed, full mass range acquisition with exceptional speed, isotopic abundance and mass resolution, all available in a single injection.

Folded Flight Path^® (FFP^®) technology and a novel data acquisition system enables simultaneous resolutions of over 50,000 FWHM, mass accuracies less than 1 ppm, and acquisition rates up to 200 spectra/second, without the need to adjust tuning or parameters. Thus, facilitating rich analyte finding and high-confidence analyte identification.

... users are able to find more analytes than ever before and confidently identify unknown components.

The Pegasus GC-HRT+ 4D takes advantage of four dimensions of separation and resolution:

• 1^st dimension chromatographic resolution
• 2^nd dimension chromatographic resolution
• High mass resolution and exceptional mass accuracy
• High Resolution Deconvolution (HRD) from the leaders in deconvolution

ChromaTOF brand software, designed specifically for HRT⁺ instrumentation and GC×GC support, adds advanced qualitative and quantitative capabilities to an all-in-one user-friendly data system.

USP 1663 provides guidance on extractables testing and a variety of analytical approaches can meet compliance. High resolution MS is often considered necessary for identification of unknowns, and sample complexity and low-level detection continue to challenge these analyses. Here, we demonstrate a workflow that uses comprehensive two-dimensional gas chromatography (GC×GC) with HR-TOFMS to help address these challenges.

Answer:
Gas chromatography separates components in a mixture by utilizing a thin silica tube coated with a stationary phase. The components, carried by a gas (the mobile phase), move at different speeds based on their affinities for the stationary phase. This differential migration leads to the separation of the components, allowing for their individual analysis and identification.

Alternative response:

• Gas chromatography is a technique for separating a mixture of volatile analytes
• The analytes are transported by a mobile phase (the carrier gas)
  • Become distributed between the mobile phase and a stationary phase
  • The Stationary Phase is attached to the inside of a very fine column
• Phases are typically characterised by their polarity
• A polar analyte will be retained by polar column for longer than a non-polar analyte
  • and vica versa

Answer:
LECO uses Agilent 8890 chromatography. The gas chromatograph includes the following features:

• Compatibility and perfect integration with the mass spectrometer
• Automatic regulation of gas flows
• Agilent supported inlets: Split/Splitless (SSL), Multimode (MMI), Programmable temperature Vaporizer (PTV) etc.
• Programmable oven, up to 450 °C
• Chromatograph compatible with Fast-GC
• The GC is completely controlled by and integrated into LECO’s ChromaTOF software

Answer:
The mass range of the Pegasus BT is from 10 to 1500 m/z. All masses are collected all the time, unlike quadrupole instruments that collect a single mass at a time (quadrupole scanning mode is single ion monitoring, SIM, quickly scanning across the mass range).

Answer:
GC×GC-TOFMS can detect discrepancies in the composition of food products, helping to expose fraudulent claims of Halal certification and ensure consumer confidence in authentic Halal products.

Answer:
By examining the chemical composition of inks and pigments, GC×GC-TOFMS provides insights into the materials used in Islamic calligraphy and manuscripts, aiding in their preservation and authentication. An example of similar work can be read in this publication on analysing the paints used by Leonardo Da Vinci.

Answer:
LECO’s GC×GC-TOFMS system utilizes two columns with different separation mechanisms, providing enhanced chromatographic resolution for the analysis of complex mixtures. In one dimension the analytes are separated by polarity, or according to boiling point. An additional dimension separates according to an alternative property, of which there are many. This results in a 3D image – the two dimensions of separation and the abundance of the analytes in the third dimension.

Answer:
LECO's StayClean^® ion source originates in the requirement for a fast source to match the speed of the TOFMS. Accomplished by reducing ion to ion interactions, such as with the walls of the source. The source was thus designed without walls – so there is nothing to clean. Massively reduced downtimes, especially for complex matrices and more reproducible results.

Answer:
Yes! With superior separation power and precision, LECO’s GC×GC-TOFMS system can uncover hidden details and confidently identify components, even in the most intricate mixtures:

• Increases detectability
• Removes analytes from matrix interference
• Separates co-elluting peaks
• Creates cleaner peaks, which match closer with libraries
• Creates structured chromatograms thus further improving identification confidence

Answer:
The cryogenic Quad Jet modulator consistently delivers reproducible quantitative results not only within the lab but also between labs worldwide. This is achieved because:

• There are two cold jets. So, eluent from the primary column does not flow into the secondary column by mistake
• The distance between cold zones is identical in every system worldwide, unlike other systems that require manual adjustment and intervention
• The modulation is completely computer controlled. This along with the 2 separate cold zones, allows for variable modulation periods in the same analysis, vastly improving separation across the chromatogram
• In the same way the primary column is temperature controlled in the primary oven, the secondary column is also independently controlled, allowing for total control of the chromatogram along the entire column setup

These four features not only improve separation and control, they are also unique to the LECO QuadJet.
