- the inner surface 1B of the cartridge body 1A is provided with a first tapered surface lg forming a fitting portion, a first straight surface lh extending downward from a step le at the lower end of the first tapered surface lg, and a first straight surface lh.
- a second tapered surface li having a smaller diameter as extending downward from the lower end of the second tapered surface, a second straight surface lj extending downward from the lower end of the second tapered surface li, and a lower end force of the second straight surface lj
- the third tapered surface lk which has a smaller diameter as it extends downward, and a force that also provides a force. In this case, both the outflow side frit 5 and the inflow side frit 3 can be held by the third taper one surface lk.
- the solid-phase extraction cartridge 1 may be formed in a syringe type capable of injecting a large amount of sample. This is because the outer surface of the cartridge body 1A is made up of the first tapered surface la4, which has a smaller upper diameter in the downward direction, and the lower end of the first tapered surface la4.
- a second taper surface la3 (having a larger angle than the first taper surface la4) having a smaller diameter on the lower side, and a third taper having a smaller diameter closer to the vertical direction extending downward from the lower end of the second taper surface la3 It consists of a tapered surface la2 and a fourth tapered surface lal that has a smaller diameter as it extends downward from a step lm formed on the tapered surface at the lower end of the third tapered surface la2. You may.
- the inner surface of the cartridge body 1A has a first tapered surface li having a smaller upward force and a smaller diameter from the lower end of the first tapered surface li (the angle is smaller than the first tapered surface li).
- the face lk and the power also come together! / Ru, but other configurations are also possible! / ⁇ .
- the outflow side frit 5 can be held by the stopper portion If formed at the lower end so as to protrude inward.
