Embodiment 1

[0021] (1) Preparation of filter rod matrix standard material containing triacetin

[0022] Purchasing raw materials such as forming paper, centerline glue, hot melt adhesive, tow and so on from the market, using ZL29 filter rod forming machine to produce filter rod sample model machine, the parameters of filter rod forming machine to produce filter rod are: glycerin application amount 50~60mg per piece, the ratio of the speed of the No. 1 opening roll to the machine speed is 1.1~1.2, the ratio of the speed of the No. 2 opening roll to the speed of the No. 1 opening roll is 1.35~1.45, and the amount of lap glue is 17~21mg / 600m , The glue amount of the inner bonding line is 17~21mg / 600m, and the speed of the machine is 600m / min. The filter rod forming machine is turned on for about 1 to 2 hours, and the standby station is stable for sampling. When sampling, according to the natural production order, each 1000 pieces produced as a group, a total of 10 groups are taken, and the ...

Embodiment 2

[0061] (1) Purchase raw materials such as forming paper, centerline glue, hot melt adhesive, and tow from the market, and use ZL29 filter rod forming machine to produce filter rod sample model machines. The parameters of the filter rod forming machine to produce filter rods are: the amount of glycerin applied 50~60mg / piece, the ratio of the speed of the No. 1 opening roll to the machine speed is 1.1~1.2, the ratio of the speed of the No. 2 opening roll to the speed of the No. 1 opening roll is 1.35~1.45, and the amount of lap glue is 17~ 21mg / 600m, the glue amount of the inner bonding line is 17~21mg / 600m, and the machine speed is 600m / min. The filter rod forming machine is turned on for about 1 to 2 hours, and the standby station is stable for sampling. When sampling, according to the natural production sequence, each 800 pieces produced as a group, if a total of 10 groups are taken, and the 800 pieces of samples in each group are fully mixed. After that, 5 filter rods were ...

Abstract

The invention relates to a filter stick matrix standard substance containing glyceryl triacetate and a preparation method thereof, which are used for the purposes of instrument calibration for testing the content of glyceryl triacetate in a filter stick by a near-infrared method, proficiency testing of different laboratories and the like. The preparation method of the filter stick matrix standard substance is characterized by comprising the following steps: (1) preparing the filter stick matrix standard substance containing glyceryl triacetate; and (2) valuing and uncertainty evaluation of the filter stick matrix standard substance. The filter stick matrix standard substance disclosed by the invention is good in stability under the condition of normal temperature, accurate in valuing method, reliable in traceability, and relatively low in total relative synthesis standard uncertainty (less than or equal to 6.0%). The matrix standard substance provided by the invention can solve the problem that an instrument cannot be calibrated when the application amount of glyceryl triacetate in a filter stick is tested by using a near-infrared method at present; meanwhile, capability verification can be carried out on different laboratories by adopting a near-infrared test method, a GC method and other methods, and the development blank of the glyceryl triacetate content matrix standard substance in filter sticks at home and abroad is filled.

Description

technical field [0001] The invention relates to the technical field of measurement and test standard value transfer, in particular to a filter rod matrix standard substance containing triacetin and a preparation method, which can be used for near-infrared method to test the content of triacetin in filter rods. Instrument calibration, proficiency testing in different laboratories, etc. Background technique [0002] In recent years, the national and industry levels have attached great importance to the research and development of reference materials. As of September 2017, the tobacco industry has a total of 11 types of reference materials that have been released or are in the state of industry review and research. However, compared with other industries, the research on reference materials in the tobacco industry lags behind. Taking the food industry as a comparison, as of September 2017, the number of reference materials for food composition analysis and testing has reached ...
