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 adsobed inside the NeedlEx. Then simply inject into a Gas Cromatograph 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 desorbtion solvents.
