[Problem] To provide a solid phase extraction cartridge that is provided with a discharge tip at a cartridge main body, is such that a tube can be connected without using a connection adaptor, and is favorable for using only a small amount of filling, thus having high analytic accuracy. [Solution] The solid phase extraction cartridge (1) results from a sample outflow-side frit (3) being mounted within a tubular cartridge main body (2), a solid phase filler (4) filling above same, a sample inflow-side frit (5) being abutted above same, and the result being stoppered, a tubular discharge tip (6) being provided below the sample outflow-side frit (3) in the cartridge main body (2). The inner surface (7B) of the discharge tip (6) is formed in a tapered shape that narrows in diameter in the upward direction, and a tube (PO) inserted from below into the discharge tip (6) makes tight contact at the top of the inner surface (7B). It is possible to easily and reliably connect the tube (PO) without using a connection adaptor, dead space is greatly reduced, and an eluate flows smoothly without waste, and so analytic accuracy increases. |
