AI Technical Summary
Technical Problem
Existing sampling methods using sharp injection needles can cut off and mix unnecessary film portions with the gel sheet, leading to noise during analysis.
Method used
A sampling pin with an elongated shape featuring multiple projections and curved portions, where at least one curved portion has a base-side peak, is used to cut and collect gel sheets, minimizing film detachment.
Benefits of technology
Prevents unnecessary film from being cut off and mixed with the gel sheet, ensuring cleaner samples for analysis.

Abstract
The present invention provides a sampling pin, sampling and placement member, sampling and placement apparatus, and sampling and placement method that can eliminate the possibility of unnecessary film being cut off and mixed in when sampling gel sheets on a film. [Solution] The sampling pin 141 has an elongated shape extending from the base to the tip. The tip includes a plurality of protrusions P and a plurality of curved portions C. The plurality of protrusions P are spaced apart in the circumferential direction. The plurality of curved portions C are formed between the plurality of protrusions P in the circumferential direction and are curved such that the peak portion D in the direction of extension of the elongated shape is directed toward the base. At least one of the plurality of curved portions C1 has a base-side peak portion PK in which the position of the peak portion D in a part of it is closer to the base than the other curved portions C2 other than at least one curved portion C1.
