Abstract

The invention belongs to the technical field of the chemical detection equipment, and specifically relates to a freezing conveying sample-injection device and method for element analyzer special sample detection. The freezing conveying sample-injection device for element analyzer special sample detection comprises a glove box, an electronic scale, an element analyzer, a freezing device and a precise sample injection device; the electronic scale and the freezing device are arranged in the glove box, a sample outlet of the glove box is connected with a sample inlet of the precise sample-injection device, the sample outlet of the precise sample-injection device is connected with the sample inlet of an element analyzer. By adopting an innovative idea for directly converting the liquid sample into a solid sample to detect, the problems that the existing detection equipment cannot accurately detect carbon, hydrogen, nitrogen, sulfur and oxygen elements in the liquid sample and an air sensitive sample and the organic elements in the liquid sample with strong volatility cannot be detected are solved.

Description

technical field [0001] The invention belongs to the technical field of chemical detection equipment, and in particular relates to a frozen transport sampling device and a method for detecting special samples of an elemental analyzer. Background technique [0002] The elemental analyzer is an instrument used to detect the content of organic elements carbon, hydrogen, nitrogen, sulfur and oxygen in the sample. However, when using an elemental analyzer for detection, some special samples, such as coal tar, highly volatile liquid samples, and air-sensitive samples, cannot accurately detect the content of carbon, hydrogen, nitrogen, sulfur, and oxygen. At present, the instrument company equips the elemental analyzer with a liquid sealer to detect liquid samples. Put the liquid sample in a tin cup, seal it with a liquid sealer, weigh it, and place it in the sample tray of the elemental analyzer for sample detection. However, when using a liquid sealer to prepare samples, a large...
