Embodiment 1

[0038] A kind of thermogravimetric analysis method that is used for the evaluation of agarwood burning smoke, comprises the following steps:

[0039] Step 1, cut 3g of Hainan artificial agarwood into small pieces, put it into a pulverizer and crush it into powder, and use it as a sample after sieving;

[0040] Step 2, weigh the sample and put 200mg in the crucible of the thermogravimetric analyzer, close the furnace body, put the furnace body of the automatic droplet continuous microextraction device, the extract solution of the automatic droplet continuous microextraction device is ethanol, and the carrier gas is nitrogen, The flow rate is 500mL / min;

[0041] Step 3: Start the thermogravimetric analyzer, set the heating program to heat from room temperature to 600°C and keep it for 10 minutes, set the heating rate to 20°C / min, set the carrier gas to air, and the flow rate to 200mL / min, and start testing after the system is stable for 10 minutes And record the thermal analysi...

Embodiment 2

[0047] A thermogravimetric analysis method for the evaluation of agarwood burning smoke, comprising the following steps:

[0048] Step 1, cut 2g of Qinan agarwood into small pieces, put it in a pulverizer and crush it into powder, and sieve it as a sample for later use;

[0049] Step 2: Weigh the sample and place 100 mg in the crucible of the thermogravimetric analyzer, close the furnace body and place the furnace body of the automatic droplet continuous microextraction device. The extraction liquid of the automatic droplet continuous microextraction device is ethanol, the carrier gas is nitrogen, and the flow rate is nitrogen. is 900mL / min;

[0050] Step 3, start the thermogravimetric analyzer, set the heating program to heat from room temperature to 600 °C and keep it for 10 min, set the heating rate to 20 °C / min, set the carrier gas to dry air, and set the flow rate to 100 mL / min. Wait for the system to stabilize for 15 min. Detect and record thermal analysis curves;

Abstract

The invention belongs to the technical field of analysis and detection, and relates to a thermogravimetric analysis method for evaluating burning smoke of agilawood. According to the method, a programtemperature control furnace body of a thermogravimetric analyzer is used for simulating a perfume channel perfume heating condition; an agilawood sample is placed into air or a synthetic atmosphere condition through the thermogravimetric analyzer, and programmed heating pyrolysis is performed; in the process, the agilawood burning smoke is carried by a carrier gas to continuously escape out of the furnace body, and then the chemical components in the burning smoke are extracted by an automatic liquid drop continuous micro-extraction device and enriched in one or more liquid droplets; qualitative and quantitative analysis is carried out on the liquid droplet components by utilizing a combined detection instrument, and thermal analysis information such as thermogravimetry, differential heat, micro-quotient thermogravimetry curve and the like of agilawood pyrolysis is obtained through thermal analysis software; and component information and change conditions of the burning smoke releasedby agilawood in the heating process are comprehensively calculated, so that the aroma quality of the burning smoke and the agilawood is analyzed and evaluated.

Description

technical field [0001] The invention belongs to the technical field of analysis and detection, and relates to a thermogravimetric analysis method for evaluating agarwood burning smoke. Background technique [0002] Agarwood is the resinous core material of some plants of the genus Agarwood in the family Daphneaceae. Agarwood is pungent, bitter, and slightly warm in nature. It has the effects of promoting qi and relieving pain, warming middle-JIAO and relieving vomiting, invigorating qi and relieving asthma. In our country, the only medicinal plant of agarwood is agarwood, and a healthy agarwood tree does not produce agarwood, only by natural factors (lightning, fire, microbial invasion, etc.) etc.) to gradually form agarwood. The history of Chinese incense has a long history. As early as the Han Dynasty, there were historical records about the use of agarwood. At present, agarwood has become a commonly used incense material. Agarwood is mainly famous for its dense oil and...
