EXTRACTION NEEDLE FOR COLLECTING VOLATILE ORGANIC COMPOUNDS IN AIR
Characteristics
■ Excellent reproducibility and simple operation Simply connect a NeedlEx needle to an AP-20 or AP-20N aspirating pump and collect a gas sample. Target compounds can be extracted selectively and rapidly. ■ Extended storage possible Extracted gases can be stored in NeedlEx needles for approximately 10 days by sealing both ends of needles using Teflon plugs. ■ No costly specialized tools required for adsorption and desorption Gas chromatograph injection port heat is used for the desorption of extracted gases. ■ Reusable By conditioning for approximately 3 minutes, NeedlEx needles can be reused approximately 25～30 times.
NeedIEx types
■ Alcohol type Short chain alcohols including methanol and ethanol, as well as low boiling point compounds such as acetone and acetaldehyde can be concentrated by factors of 50 and greater. ■ Organic solvent type Organic solvents such as ethyl acetate, isobutyl alcohol, methyl isobutyl ketone, toluene, xylene, styrene, etc. ■ Fatty acid type Connecting to an aspirating pump Fatty acids such as n-butyric acid, isobutyric acid, isovaleric acid, and propionic acid. (The polymer used in this type is a highly heat-resistant polymer selected for its superior fatty acid adsorption and desorption capabilities.) Trimethylamine type Short chain amines such as trimethylamine.
