Stabilwax®FAMEs, flavor compounds, essential oils, solvents完美分析
|
|
Stabilwax® (polar phase; Crossbond® Carbowax® polyethylene glycol) • General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, US EPA Method 603 (acrolein/acrylonitrile). • Resistant to oxidative damage. • Temperature range: 40°C to 250°C. • Equivalent to USP G14, G15, G16, G20, G39 phases.Our polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns. The bonding mechanisms produce a column that can be rejuvenated by solvent washing. Compared to silicone stationary phases, PEG phases are more resistant to damage from strongly acidic or basic volatile compounds, including inorganic acids and volatile inorganic bases. 1. acetone 2. ethyl acetate 3. methylene chloride (solvent) 4. hexanal 5. amyl acetate 6. 1-butanol 7. 3-methyl-1-butanol 8. 1-pentanol 9. 3-octanone 10. 3-octanol 11. nonanal 12. 1-octen-3-ol 13. furfural 14. benzaldehyde 15. octyl alcohol 16. phenylacetaldehyde 17. α-terpineol 18. 2,4-nonadienal 19. 2,4-decadienal 20. benzyl alcohol Column: Stabilwax®, 30m, 0.32mm ID, 1.0μm (cat.# 10654) Inj.: 1.0μL split injection of a synthetic mushroom aroma Conc.: 10ng per component Oven temp.: 40°C to 220°C @ 6°C/min. Inj./det. temp.: 260°C Carrier gas: hydrogen Linear velocity: 40cm/sec. FID sensitivity: 4 x 10-11 AFS Split ratio: 100:1 |
