Application Detail (App ID: 19287)

Part No:7HM-G017-11
Phase:Proprietary Pesticides Phase
Dimensions:30 meters x 0.32 mm x 0.25 µm
Oven Profile:30°C for 4 min to 50°C @ 30°C/min for 1 min to 70°C @ 15°C/min for 1 min to 115°C @ 20°C/min for 2 min to 200°C @ 30°C/min.
Carrier Gas:Constant Flow Helium, 2.3 mL/min
Injection:Pulsed :1 1 µL @ 250°C
Detection: Electron Capture (ECD) (340°C)
Note:Derivatization: Add 1mL of MTBE to the eluent in a screw cap vial or test tube. Heat the sample at 50ºC for 2 hours. Remove and allow the sample to cool to room temperature. Slowly add 10mL of saturated sodium bicarbonate and invert the sample several times releasing carbon dioxide gas frequently. Aspirate 100µL of the organic layer and transfer to a 2mL vial with insert. Add 10µL of internal standard (1,2,3-Trichloropropane) and inject into GC-ECD system.
