Open Air Desorption Ionization of Apple Juice
DART®-MS analysis of Apple Juice is facilitated by using Experiment modules that position samples in the desorption ionization region of the DART® source
Samples can either be quickly inserted into the desorption ionization region using an automated X-Y sample positioning stage
Individual aliquots of juice or extract are positioned on separately addressable glass inserts to facilitate more reproducible analysis
The DART® SVP control software controls the type of movement, gas temperature, ionization mode, and exposure time for the experiment
48-Well Plate with Inverted Glass Inserts
• Sampling using the 3+D scanner module.
• Microtiter plate populated with glass inserts in every other row
• Up to 10 ul of a liquid samples can be pipetted onto the top surface of the glass inserts
• One glass insert per sample isolates each sample from the next so that each analysis starts with the same temperature surface
• The Angle DART® SVP option is used for more efficient desorption
• VAPUR® is used to permit sampling from the furthest position on the plate
APPLE JUICE, DART®-MS
• 10 ul of Apple Juice applied to top of insert.
• Carbohydrate related ions present and
dominate the positive ion mass spectrum
• Few ions detected in the negative ion mass spectrum
• Analysis complete in 10 seconds per sample using automated positioning with the 3+D Scanner
3+D Scanner, Analyzing a Pesticide Mixture
• Pesticide Mix
• Contained 140 pesticides
• Most of the pesticide standards were obtained from the U.S. EPA Pesticide Repository (Ft. Meade, MD), whereas others were obtained through Fluka/Sigma Aldrich (St. Louis, MO), Wako Chemicals USA (Richmond, VA),Honeywell Riedel-de Haën (Seelze, Germany), and EQ Laboratories, (Atlanta, GA).
Pesticide Standards in Apple Juice
Positive ion DART®-MS mass chromatograms for three of the major protonated pesticides detected in 20 replicate analysis and undetected in 4 control samples
Negative ion DART®-MS mass chromatograms for three of the major pesticides detected in 20 replicate analysis and undetected in 4 control samples
