A plasma spectrometry method with high reproducibility of plasma light emission is described, wherein the method comprises: a detection step of applying a voltage, thereby detecting the resulting plasma light emission; and non-detection step of detecting no plasma light emission.

Plasma spectrometry method

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.

Chip for plasma generation, plasma generator, and plasma spectrometry method

A chip for plasma generation, a plasma generator, and a plasma spectrometry method are described, having high reproducibility of plasma light emission without a requirement of a discharge unit for removing air bubbles, wherein the chip includes a channel comprising a first region, a narrow portion, and a second region, where 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.

A mixing apparatus includes: a mixing container with a discharge port for discharging mixed liquid; a filter paper covering the discharge port to temporarily retain the liquid; a receiving unit with a waste liquid collecting portion for receiving a first liquid discharged from the discharge port through the filter paper, and a measuring portion for receiving a second liquid subjected to treatment different from treatment for the first liquid; and an operation portion for enabling selection between a first receiving state in which the waste liquid collecting portion receives the first liquid and a second receiving state in which the measuring portion receives the second liquid, and also for controlling the movement of the first liquid or the second liquid.
