Application Detail (App ID: 17906)

Column: Luna® 3 µm PFP(2) 100 Å, LC Column 150 x 2 mm, Ea

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: 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.
