Use a digital pipette to add exactly 5.00 mL of methanol into the tube with the folded bill. Invert the tube for at least 10 minutes. Using tweezers, carefully remove the bill from the tube. Try to leave as much of the methanol in the tube as possible. WebIn GC, heated, volatile compounds are injected into a flowing gas stream and separated as that stream flows through a long hollow tube (sometimes tens of meters in length) coated with a stationary phase material. In GC MS chromatography, the fractionated compounds are then ionized (typically by electron ionization) and injected into the mass ... contributing ira
