Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] It should be noted that when a component is said to be "mounted on" another component, it may be directly on the other component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or there may ...

Abstract

The invention relates to the infrared spectrometer accessories including: a sample chamber, which is provided with a sample cavity and a detection optical path channel communicated with the sample cavity; an ultrasonic generator, including a transducer and transmitting the acoustic energy from the transducer to the horn within the sample chamber. In the embodiment provided by the present invention, while the infrared spectrometer is detecting, the sample is evenly dispersed by the ultrasonic generator, so that it can avoid or slow down the sedimentation under the action of gravity, and ensure that the reactants evenly react with each other during the detection process. The temperature control part can control the temperature of the sample, so that the infrared spectrometer can capture the infrared spectrum changes of the sample at different temperatures, so that the experimenter can more accurately observe the change of the functional group in the liquid phase chemical reaction process, and obtain more accurate experimental data.

Description

technical field [0001] The invention relates to the field of analysis and detection, in particular to an accessory of an infrared spectrometer. Background technique [0002] Infrared spectrometer is an instrument that detects and analyzes the structure and chemical composition of substances based on the difference in infrared light absorption of different substances. It is widely used in the fields of material science, polymer chemistry, petroleum industry, biomedicine and daily chemical industry. However, the structure and form of the substance to be tested in different fields are often very different, so it is necessary to place the sample in a suitable accessory before the test so that the infrared light can fully contact the substance to be tested. The commonly used accessories can be divided into transmission accessories. There are two types of attachments, attenuated total internal reflection (ATR) and attenuated total reflection (ATR), among which the transmission att...
