	Organochlorine pesticide mix C #1 (cat.# 32296)
Diluent:	Hexane
Injection	Direct
Liner:	Drilled Uniliner
Inj. Temp.:	220 °C
Oven Temp.:	80 °C (hold 1 min) to 300 °C at 9 °C/min (hold 10 min)
Carrier Gas	He

Detector	ECD @ 310 °C
Notes	Sample: 0.5 - 1.0 mL solvent extracted sample exchanged into hexane Standards and surrogates were spiked into hexane Tube: 3 mL, 250 mg CarboPrep 90 Tube conditioning: Apply 2 mL CH₂Cl₂:hexane (20:80) and pass through tube Extract cleanup: Prepare collection rack with vials, place under each tube. Add 0.5 - 1.0 mL of extracted sample to tube and collect all solutions passing through. Do not expose carbon bed to air. Add 20 mL of CH₂Cl₂:hexane (20:80) to tube and allow it to elute using gravity feed. Extract concentration: Solvent exchange extract to hexane Do not allow extracts to dry completely Concentrate extract to 0.5 - 1.0 mL Sample is ready for analysis.
