CheMS

Software for simplified mass spectrometer operation and compound identification

The CheMS user interface simplifies the mass spectrometry experience and makes it more  accessible in chemistry and biochemistry laboratories. The user interface allows users to quickly select the workflow and type of compound they wish to analyze in just a few clicks  of the mouse and the software automatically optimizes the ion source and data acquisition parameters to ensure they get the data they need for decision-making. This allows the chemist to obtain optimal data without needing to be an expert in mass spectrometry.

  • Effortless method and instrument set-up for a range of sample
    introduction techniques, optimized for your sample type.
  • Simplified mass spectral interpretation with automatic identification
    of peaks related to your compounds of interest.
  • Flexibility to scan across the full mass range to search for unkowns, or
    to focus on a specific area for a compound of interest.
  • Integrated with Advion sampling techniques; direct syringe injection,
    Plate Express (TLC/CMS) and ASAP direct probe analysis.
  • Works in conjunction with Mass Express for fully versatile software.

Fast Screening for Purity and Adulterants in Coconut Oil by ASAP® Compact Mass Spectrometry

The expressionL CMS coupled with the Atmospheric Solids Analysis Probe (ASAP®) is used to determine purity and detect adulterants in coconut oil. In this application note, pure coconut oil is tested against a sample of coconut oil adulterated with canola oil for comparative data analysis and a fast and easy method for purity analysis.

iASAP Analysis of Air-Sensitive Compounds via Inert Sampling Techniques

Many chemical reactions carried out by synthetic chemists involve air-sensitive compounds such as metal catalysts and organometallics and must therefore be carried out in a glove box or using a Schlenk line to prevent oxidation and hydrolysis. Sampling and transportation of these samples to a mass spectrometer by an Atmospheric Solids Analysis Probe (ASAP ®)…

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 Volatile Mass Spectrometry

In this application note, we demonstrate the use of the Advion expression CMS with a volatile 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 and…
