Abstract: A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.

Abstract: A mass spectrometry system and a working method and an application thereof, and a sampling device. The mass spectrometry system includes an ion source, a sampling device and a mass spectrometer. The sampling device includes: a guide rail; a support adapted to move on the guide rail; a bearing member made from a hydrophobic material with two ends being fixed to the support; a plurality of containers for containing samples arranged on the support; a plurality of transport members made from a hydrophilic material and including a first portion provided on the bearing member and a second portion connected to the first portion and extending into each container; adjacent transport members being not in contact; and a drive module configured to drive the support to move on the guide rail such that a central axis of an exit port of the ion source passes through the first portion.
