Packed column to determine the moisture co
ntent in the smoke-use explosive beads. Details:
Name: Packed column
Specification: 2m*3mm
Model: PQ
Particle size: 80-100 mesh
Application: Determination of moisture co
ntent in popcorn
In order to accurately determine the moisture co
ntent of the tobacco cracked beads, the influence of sample size and operating co
nditions on the detection effect was investigated. Haohan·Chromatography· established a gas chromatography-thermal co
nductivity detector (GC-TCD) for the moisture co
ntent of the tobacco cracked beads Detection method. Using the existing blasting beads, the method's standard curve formulation, quantification limit, spike recovery rate, and intraday (inter-day) precision were investigated. The results showed that: (1) The recovery rate of high, medium, and low standards was between 98.95% and 104.48%; (2) The method quantification limit was 0.0577 mg/mL; (3) The intra-day precision was 3.47%, and the intra-day precision was 4.05. %. Therefore, the use of GC-TCD can sensitively detect low-co
ntent moisture, the quantitative results are reliable, and it is suitable for the determination of moisture co
ntent in tobacco popcorn.
