What applications are included?

LECO_App1Pairing Olfactory Detection with GC-MS to Clarify Identification of Isomers 
Sometimes, even the highest deconvolution and mass spectral pattern matching can still result in ambiguous identifications, such as in the case of stereoisomers. By adding olfactory detection to your GC-MS, these differences can be resolved.

LECO_App2Comprehensive Evaluation of Scotch Whisky Aroma Profiles Using

With the high value of liquors such as Scotch Whisky, it is a tempting product for adulteration, substitution, or other methods of defrauding customers. A non-target analysis method such as the GCxGC-TOFMS provided by the Pegasus® BT 4D allows for quick, accurate, and reliable sample characterization to address these issues.

LECO_App3Characterization and Comparison of Whiskey Aroma Profiles with
GC-TOFMS and ChromaTOF Sync 

Complete aroma characterizations of whiskeys and similar products are useful in understanding similarities and differences and observing consumer trends. Statistical analysis tools such as ChromaTOF® Sync enable rapid comparison to detect production changes and see differences among competitors.

LECO_App4Statistical Differentiation of Baijiu Spirits Using SPME-GC-TOFMS and Sync Software 
One of the world’s most consumed spirits, Baijiu aroma-types help set this spirit’s value. Comprehensive GC-MS analysis and statistical differentiation of the resulting data using ChromaTOF® Sync can help distinguish between the various origins of Baijiu and determine what is contributing to the various aroma profiles of this spirit.

LECO_App5FAST GC-TOFMS and Hydrogen Carrier Gas: An Enhanced Solution for the Analysis of Citrus Essential Oils
With helium shortages becoming more frequent, labs everywhere are looking for a more affordable way to continue their analyses. LECO’s StayClean® Ion Source design allows the use of hydrogen as a carrier gas without sacrificing sensitivity or speed. Hydrogen carrier gas can even result in faster run times with the same sensitivity.

LECO_App6Comparison of Traditional Chardonnay and Buttery Chardonnay with Data Processing for Sample Sets 
When comparing very similar samples, even the power of GC-MS might not be enough to easily tell where significant differences and trends are. See how a statistical analysis tool like ChromaTOF® Sync can be used to characterize and compare buttery and traditional Chardonnays.


LECO_App7Quantification of 2,4,6-trichloroanisole to Detect Cork Taint Fault in Wine with the Pegasus BT 
When analyte quantities in the low parts-per-trillion can throw off your product and create unpleasant off-odors, such as cork taint in wines, an instrument sensitive enough to detect it even at these low levels is an essential part of your lab. See how easily LECO’s Pegasus® BT can detect cork taint in wine samples.


LECO_App8A Rapid, Robust and Sensitive Analysis of Tea Tree Essential Oil Quality by GC-TOFMS with Hydrogen as Carrier Gas 
Tea tree essential oil is one of many essential oils with wide-ranging commercial use. Using hydrogen as a carrier gas can result in faster GC-MS analysis of this useful oil without sacrificing any of the sensitivity in the results.


LECO_App10Statistical Differentiation of Pesto Products Using SPME-GCxGC-TOFMS and ChromaTOF Tile Software
When complex data sets become overwhelming, their utility diminishes. Innovative statistical tools such as ChromaTOF® Tile revolutionizes the comparison of multiple GCxGC-MS data sets in a fast and user-friendly way. See how it makes sense of various pesto sauce samples.


LECO_App11Comprehensive Evaluation of Pesto Aroma Profiles Using SPME-GCxGC-TOFMS 
Customers can’t always explain why they prefer one aroma profile over another, but a comprehensive aroma analysis combined with customer feedback can provide valuable insight into product development and quality control such as in commercially-available pesto sauces.


LECO_App12Nutmeg Essential Oil: Sensory Directed Analysis of GC-MS Data via Olfactory Detection 
Flavor and fragrance are intrinsically linked, so a full characterization of a food, flavor, or fragrance sample should include an olfactory detection element. Splitting the GC separation to both MS and olfactory detection allows for complimentary analysis, as demonstrated with nutmeg essential oil.


LECO_App13Characterization and Comparison of Flavored CBD Beverages 
Target screening and non-target screening ask different analytical questions that may need different approaches to solve. See side-by-side comparisons of GC-TOFMS and GCxGC-TOFMS in the analysis of flavored CBD beverages.

Understanding Off-flavors and Malodors
presented by Ray Marsili
Utilizing gas chromatography-olfactometry (GC-O) can help identify active odor compounds in complex mixtures. But, what happens if GC-O does not identify a compound, but an off-flavor or malodor is still present?

Towards Better Tasting Vegetarian Foods 
presented by Hans-Gerd Janssen and Ed Rosing
An overview of GCxGC mass spectrometry and improved flavors in vegetarian foods is presented. ChromaTOF Tile was utilized to review chromatography data.

Flavor Ingredient Analyses through GC-MS 
presented by Marlene Moskowitz
Gas chromatography mass spectrometry data can be analyzed to determine the region of origin of various ingredients, such as vanilla or cinnamon, based on known analytes.

Challenges and Solutions in Aroma Profiling 
presented by Lena Dubois and Liz Humston-Fulmer
The Pegasus BT 4D determines key aromatic compounds in pumpernickel bread; GCxGC benefits for the analysis of beer and hops samples.
