expressionS CMS

for synthetic chemistry

The expression family of compact mass spectrometers provide essential information quickly and improves the chemist’s workflow. Designed with the synthetic organic chemist in mind, the expressionS is a flexible, transportable mass detector for small molecule analysis.

Unrivalled utility and flexibility

Reaction Monitoring

  • Compound identification for batch and flow chemistry
  • Confirm identity and purity quickly and accurately

Purification

  • Mass directed fraction collection for flash chromatography, Prep-LC and SFC

A versatile mass detector for:

  • Coupling to any (U)HPLC systems
  • Food safety
  • Water purity
  • Clinical diagnostics

My recent initiative in providing and finding research funding has resulted in the purchase of the first Advion expression compact mass spectrometer to be installed in Australia in our research laboratory. This will improve the quality of the decision making process of my PG students in the research place leading to more efficient research outcomes and provide a mass spectral service to disciplines in our college at RMIT University.” Helmut Hugel – RMIT University, Australia

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…

Screening of Dietary Supplements by ASAP® Compact Mass Spectrometry

In this application note, we demonstrate the use of the Advion expressionL CMS with an atmospheric solids analysis probe (ASAP) ion source to analyze two supplements (figure 1) that contain DMBA, a synthetic stimulant that has not been tested on humans. The substance is the chemical cousin to drug DBAA, which is currently banned by…
