Perfluoroalkylated substances (PFASs) in Foods by LC/MS/MS

Application Detail (App ID: 17906)

Part No:00F-4447-B0
Dimensions:150 x 2 mm ID
Elution Type:Gradient
Elution A:Water + 10 mM Ammonium Acetate
Elution B:Methanol + 10 mM Ammonium Acetate
Gradient Profile:
Step No. Time (min) Pct A Pct B
1 0 70 30
2 29 10 90
3 30 0 100
4 34 0 100
5 37 70 30

Flow Rate:0.2 mL/min
Col. Temp: 40 °C
Detection: Mass Spectrometer (MS) @ amu (40°C)
Detector Info: AB Sciex API 2000™
Mode: ESI-negative
Note: 5 time windows were set on the MS-detector so only the relevant MRM’s were scanned to increase sensitivity. Three of them are visible as steps in the baseline.
Note:The application was kindly provided by Dipl. Ing. (BA) Sabine Gabriel from the DVGW Technologiezentrum Wasser (TZW) in Karlsruhe, Germany.
