Abstract

The present invention relates to a composition analysis technology of ultramicro-volume liquid by laser ablation plasma mass spectrometry. Using a pipette gun to extract the liquid to be detected in a low-temperature environment, dropping the liquid into a dropping pit in a dropping plate, the liquid level is slightly higher than an overflow table in the dropping plate; dropping different liquid samples into different dropping pits by the same method; gradually covering the dropping pit with an analysis film having an area 1.5 times larger than that of the dropping plate from one side of the dropping plate, tightly adhering the thin film onto the dropping plate by using a transparent adhesive tape, the thin film is in close contact with the liquid level; placing the dropping plate covered by the thin film in a LA-ICPMS universal solid sample chamber, and then setting parameters for ablation.
