NeedlEx is an extraction needle for collecting volatile organic compounds in air to apply it to Gas chromatograph.
Characteristics are as following.
1. 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.
2.Extended storage possible
Extracted gases can be stored in NeedlEx needles for approximately 10 days by sealing both ends of needles using Teflon plugs.
3.No costly specialized tools required for adsorption and desorption
Gas chromatograph injection port heat is used for the desorption of extracted gases.
By conditioning for approximately 3 minutes, NeedlEx can be used approximately 25-30 times.
