給你一個我們的方法, 供您參考: For the GC program, each aqueous sample was diluted with 50% formic acid at a 1:1 (v:v) ratio, and the dilution was then injected into the GC inlet in the split mode at an initial temperature of 200 oC. With the helium gas flow at 3.8 mL/min, the vaporized sample passed through an Agilent 19095F-123 capillary column. For the separation of VFA species, the GC oven was initialized at 70 oC for 3 min and then ramped to 180 oC in 11 min and held at the high temperature for 4.5 min. The FID detector was prepared at 250 oC with the hydrogen flow at 30 mL/min and air flow at 400 mL/min, together with a makeup flow of helium at 25 mL/min. |
