WHAT'S NEW WITH DART MS? April 2014
The Latest Developments in Direct Analysis in Real Time Mass Spectrometry
|
|
We would like to let you know about two presentations at the upcoming AOCS meeting in San Antonio May 4-7, showing how our Direct Analysis in Real Time Mass Spectrometry (DART MS) system can be utilized for rapid determination of edible oil composition and quality.
In separate presentations Brian Musselman of IonSense, and Susan Seegers, of Bunge NA, will be speaking about methods for using our DART MS technology in Wednesday morning's Analytical session
Please contact me to set up a time to talk at the AOCS Conference May 4-7th or follow up at your convenience to learn more about DART MS for your applications. Thanks.
Regards, Jeff Zonderman Director Market Development IonSense Office 781-231-1739 Work Cell: 617-504-3717 zonderman@ionsense.com

Determination of Supplement Identity and Quality by Using DART-Mass Spectrometry for Rapid Triglyceride Analysis

Abstract: Nutritional supplements incorporate a wide variety of plant materials. Some supplements are single plant but often different tea leaves and even chemicals are added to produce products with the desired composition. As the quality control of these materials must improve with new regulations the need for relevant chemical test increases the burden on small manufacturers and exporters. We have completed analysis of a wide variety of medicinal supplements utilizing Direct Ionization in Real Time ambient ionization mass spectrometry. The method provides an easy means to complete chemical analysis with little sample prep. During these investigations we have been able to generate lipid profiles for the triglycerides in just seconds per sample. Statistical analysis of the data can be used to determine the presence / absence of different plant materials. The method affords a rapid means to check for sample composition and even quality as detection of irregular lipid profiles is made possible even when small concentrations of lipids are present as in the case of dried leaves.

Identification of Lipid Oxidation Products Using SPME-DART-QTOF

Abstract: Typically, a variety of gas chromatography (GC) methods have been used to evaluate oxidation products in edible oils. There are many different ways to introduce the sample into the GC such as cold-trapping, gas sampling, and more recently, solid-phase microextraction (SPME). Coupled to a mass spectrometer, these methods can concentrate, separate, and identify oxidation products. Direct analysis in real time (DART) is an ambient ionization technology used to introduce samples into a mass spectrometer. When used in conjunction with a quadrupole time of flight (QTOF) mass spectrometer, samples can be quickly analyzed with high mass accuracy. This methodology was applied to oxidation products in edible oils. Because these oxidation products are in low concentrations, SPME was also employed to concentrate the volatiles and used in conjunction with the DART. The SPME fiber was then directly desorbed in the DART stream and the oxidation products introduced into the QTOF.
