What is Ffap column?
What is Ffap column?
Agilent J&W DB-FFAP is a nitroterephthalic-acid-modified polyethylene glycol (PEG) column of high polarity for the analysis of volatile fatty acids and phenols. It is a close equivalent to USP phase G35 and replaces OV-351.
What type of column is used in gas chromatography?
Two types of columns are used in gas chromatography: packed columns and capillary columns. Short, thick columns made of glass or stainless steel tubes, packed columns have been used since the early stages of gas chromatography.
What does Ffap stand for?
|FFAP||Fédération Française des Artistes Prestidigitateurs (French: French Federation of Artists Magicians)|
|FFAP||Fédération Française des Apiiculteurs Professionnels (French: French Federation of Beekeeper Professionals)|
How do I clean my GC column?
A capillary column needs to be solvent rinsed when it becomes contaminated with residues. In many instances, this is the only reliable method to remove contaminants. Baking out the column at high temperatures often does not remove some of the contaminants and can reduce the life of the column.
What is the purpose of the Agilent hp-FFAP column?
HP-FFAP Columns Agilent J&W HP-FFAP is designed primarily for the analysis of organic acids, free fatty acids, or samples that require quantitation of acidic impurities. The FFAP stationary phase is modified with acid to provide a very inert column that can accommodate the demanding analysis of acids dissolved in water.
How is the CB capillary column used in GC-FID?
After extraction of fatty acids from plasma, a highly polar CP-Wax 58 (FFAP) CB capillary column was employed to directly quantitate fatty acids. Fifteen fatty acids (C10:0 to C22:0) were detected and separated. This method facilitated the assay of saturated fatty acids in medical laboratories.
How is the stationary phase of HP-FFAP modified?
The FFAP stationary phase is modified with acid to provide a very inert column that can accommodate the demanding analysis of acids dissolved in water. Free fatty acids up to C24 can be analyzed by HP-FFAP without costly and time-consuming derivatization.
How are fatty acids separated in a GC column?
Fifteen fatty acids were separated using a DB-FFAP (nitroterephthalic acid modified polyethylene glycol) capillary GC column (30 m×0.32 mm i.d.) with a total run time of 20 min. The method was validated in terms of specificity, linearity, precision, accuracy, sensitivity, and robustness.
