Chip for Plasma Generation, Plasma Generator, and Plasma Spectrometry Method

摘要

A chip for plasma generation, a plasma generator, and a plasma spectrometry method, having high reproducibility of plasma light emission are described, wherein the chip for plasma generation contains a channel, wherein the channel has a first region, a narrow portion, and a second region, wherein the narrow portion is in communication with the first region and the second region and has a cross-sectional area smaller than the first region and the second region, and the chip further includes an air bubble movement prevention unit that prevents air bubbles generated in the narrow portion from moving from the narrow portion toward the upstream side of the narrow portion.

主权项

1. A chip for plasma generation comprising:
a channel configured to preserve a conductive solution, wherein the channel comprises a first region, a narrow portion, and a second region from the upstream side toward the downstream side, wherein the narrow portion is in communication with the first region and the second region and has a cross-sectional area smaller than the first region and the second region, and wherein the chip further comprises an air bubble movement prevention unit configured to prevent air bubbles generated in the narrow portion from moving from the narrow portion toward the upstream side of the narrow portion.
