Identification of a Pesticide Used in Lawn Care by vAPCI Compact Mass Spectrometry

At regular intervals throughout the year a local lawn service applies pesticides to the lawn surrounding the Advion headquarters in Ithaca, NY. The grass is very uniform and not a single dandelion or crabgrass plant is visible – so we wondered, what chemical do they use? After an application in the early spring, we sampled…

Analyses of Different Grades of Olive Oil by Vapor Mass Spectrometry

In this application note, we demonstrate the use of the Advion expression CMS with a vapor APCI (vAPCI) ion source to analyze extra-virgin, virgin, and lampante olive oil samples. We show statistical analysis allowing us to categorize and identify olive oil samples by their grade. This technique allows us to test individual olive oil samples…

Classifying Cheeses by vAPCI Compact Mass Spectrometry

Cheese is one of the world’s most popular food types, with a wide variety available for consumers. The scents and flavors of cheeses, so characteristic to each type of cheese, stem from a complex mixture of chemicals, including free fatty acids. While this mixture is affected by a wide variety of factors we can use…
