Discovering the Scent of Celery: HS-SPME, GC-TOFMS,and Retention Indices for the Characterization of Volatiles

Here, we analyze a celery sample with HS-SPME coupled to GC-TOFMS. Hundreds of analytes were detected in this complex sample with many contributing important odor characteristics. The resulting data provides valuable information to characterize the aroma profile of celery by determining individual analytes.Learn more...

Comparison of Aroma and Flavor Profiles of Strawberry-Flavored Candy and Fresh Strawberries

A fresh strawberry and a strawberry-flavored candy were analyzed and compared on LECO Pegasus® BT GC-TOFMS. Hundreds of analytes were determined and deconvolution provided the ability to fight chromatographic coelutions uncovering differences that were hidden in the TIC and provided more insight to the flavor characteristics. Compound classes were investigated with lactones, ethyl esters, and sesquiterpenes compared between each sample.Learn more...

Discovery of Sulfur-Containing Compounds in Broccoli with GC-TOFMS

The Pegasus® BT rapidly provided information on these analytes in order to determine those that were sample-distinguishing. ChromaTOF brand software's automated data analysis tools and peak property filters were used to specifically focus on sulfur-containing compounds. GC-TOFMS let you uncover more than in your standard analysis. Ref. 203-821-531Learn more...

Tasting “Weird and Wild” Jelly Bean Flavors Using HS SPME Gas Chromatography Mass Spectrometry

This note demonstrates the ease-of-use and capabilities of a LECO's Pegasus BT - GC-TOFMS a benchtop time-of-flight mass spectrometer to effectively differentiate exotic flavor profiles in store-purchased jelly beans. Ref. 203-821-529Learn more...

New Pegasus® BT ! Characterization of Fruit Tea Beverages

The Pegasus BT provides a complete aroma profile for every sample, from every run. The ability to determine individual analytes offered the opportunity to compare and contrast the samples and learn more from a standard analysis. Ref. 203-821-523Learn more...

New Pegasus® BT! Rapid Screening for Contact Allergens in Perfumes with GC-TOFMS

A rapid GC-TOFMS method was developed to separate and detect a target set of 24 regulated contact allergens in approximately 5 minutes. In addition to the target allergens, the data also provides excellent characterization information for non-targeted aroma analytes within complex perfume samples. Ref. 203-821-519Learn more...

New Pegasus® BT! Quantification of 2,4,6-trichloroanisole to Detect Cork Taint Fault in Wine

The Pegasus BT provides full m/z range data and sensitivity which make it ideal for screening target analytes and/or general unknowns. The better than nominal mass information generated by the Pegasus BT allowed for further distinction of the target analyte from a matrix interference at the very lowest concentrations. Ref. 203-821-517Learn more...

New! Quantification of Contact Allergens in Personal Care Products with GC and Full Mass Range TOFMS

Pegasus HT and the ChromaTOF deconvolution and calibration features demonstrated the potential of this technology for the investigation of contact allergens in cosmetic and personal care products. In particular, the HT's full mass range sensitivity and speed with unparalleled deconvolution capabilities allowed to see peaks that may be hidden in a standard analysis. Ref. 203-821-515Learn more...

New! Detection of Cork Taint Fault in Wine Using HS-SPME and GC-TOFMS for the Quantification of 2,4,6-trichloroanisole

The coupling of a HS-SPME sample preparation step together with the power of the Pegasus HT and the ChromaTOF deconvolution and calibration features, allowed the detection of very low concentration- at parts-per-trillion levels- of 2,4,6-trichloroanisole (TCA) in a real wine samples. This component, as well established, is responsible for the cork taint fault also at very low concentrations. Ref. 203-821-516Learn more...

New! Differentiation of Fresh and Oxidized Wine Samples with HS-SPME, GC-TOFMS, and GC×GC-TOFMS

Pegasus HT and Pegasus 4D systems were used to differentiate two wine samples namely one fresh and one oxidized by the presence of oxygen inside the bottle. Thanks to the increased peak capacity and sensitivity offered by the coupling of a secondary column on the GCXGC system, it was possible to assign correctly the components formed during the oxidation process. Furthermore, LECO’s Deconvolution tool allowed the correct identification of the components well resolved or masked from the sample matrix. Ref. 203-821-514Learn more...

Non-Targeted and Targeted Aroma Analysis of Name-Brand and Imitation Perfume Samples by GC×GC-HRT

High resolution HR-TOFMS delivered accurate mass data formula determinations and more confident identifications of unknowns. Ref: 203-821-500Learn more...

Improved Identification of Brand-Distinguishing Analytes in Perfume Samples with GC×GC and HR-TOFMS

High resolution TOFMS adds another layer of information to the analysis with accurate mass data that are used for definitive formulae determinations and confident analyte identifications.Learn more...

Differential Analysis of Perfumes with GC-TOFMS

Pegasus HT GC-TOFMS system provides a comprehensive non-targeted view of the sample by providing full mass range sensitivity and speed. Learn more...

Improved Characterization of Perfumes with GC×GC-TOFMS

GC×GC provides improved detectability, increased peak capacity, and structured chromatograms to combine for more information on more analytes within a complex perfume sample.Learn more...
