填充柱测定烟用爆珠中的水分含量
填充柱测定烟用爆珠中的水分含量 详细信息：

名称：填充柱

规格：2m*3mm

型号：PQ

粒度：80-100目

应用：烟用爆珠中的水分含量测定

为准确测定烟用爆珠的水分含量,考察了样品量、操作条件对检测效果的影响,浩瀚·色谱·建立了烟用爆珠中水分含量的气相色谱-热导检测器(GC-TCD)检测方法。利用现有爆珠,对该方法的标曲制定、定量限、加标回收率、日内(间)精密度进行了考察。结果显示:(1)加高、中、低标的回收率在98.95%～104.48%之间;(2)方法定量限为0.0577mg/mL;(3)日内精密度3.47%,日间精密度4.05%。因此,利用GC-TCD能灵敏检测出低含量的水分,定量结果,适用于烟用爆珠中水分含量的测定。

Name: Packed column

Specification: 2m*3mm

Model: PQ

Particle size: 80-100 mesh

Application: Determination of moisture content in popcorn


In order to accurately determine the moisture content of the tobacco cracked beads, the influence of sample size and operating conditions on the detection effect was investigated. Haohan·Chromatography· established a gas chromatography-thermal conductivity detector (GC-TCD) for the moisture content 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-content moisture, the quantitative results are reliable, and it is suitable for the determination of moisture content in tobacco popcorn.
