Paper Chromatography - BioGlobaX
www.bioglobax.comIn capillary columns, which contain no packed solid support, the liquid stationary phase is deposited on the inner surface of the column and may be chemically bonded to it. SOLID STATIONARY PHASE This type of phase is available only in packed columns. In these columns the solid phase is an active adsorbent, such as alu-

www.agilent.comnonpolar capillary columns that separate hydrocarbons by boiling point characteristics are typically used. Boiling point columns provide good resolution for the heavier hydrocarbon fraction. However, the resolution of the light hydrocarbon frac - tion suffers when C1 …
METHANOL 2000
www.cdc.govPositive identification can be confirmed by dual column chromatography with a 100% PEG capillary column. Mass spectrometry can also be used as a confirmation aid. OTHER METHODS: This method updates and replaces NMAM 2000 (August 15, 1994), which combined and replaced Method S59 [3] and P&CAM 247 [4].
Split/Splitless Gas Chromatography Injection
www.shsu.edusplit injection. If the concentration of an analyte is high, say, 25 µg analyte/ µL—pretty high for capillary columns and 1 µL is injected, the analyst—that’s you—chooses the split injection mode and opens the split valve before the 1 µL injection is made. (With autosamplers and multiple samples this would be programmed into the ...
HYDROCARBONS, HALOGENATED 1003
www.cdc.govThe choice of capillary column or analytical parameters may be modified to circumvent such interferences. OTHER METHODS: This method is an update for NMAM Method 1003 (Issue 1, 2/15/84) [2]. Trichloroethylene, NIOSH Method 1022, was included in this method update [3]. Method improvements include higher recoveries at lower sample recovery
