NeedlEx is an extraction needle for collecting volatile organic compounds in the air. NeedlEx is a very simple to use system.
Simply attach to a Kitagawa AP-20 Aspirating pump & draw a sample. The VOCs are absorbed inside the NeedlEx. Then simply inject into a Gas Chromatograph using a gas tight syringe, the heat from the injection port desorbs the target gases. (Note: injection temperature differs depending on target gas) No need for special tools or desorption solvents.
