红茶吡虫啉检测数据

对本公司生产的红茶进行抽样检测，检测项目吡虫啉含量，吡虫啉含量是其食品安全的重要指标，从而为红茶质量分析评价提供事实依据。数据采集，随机抽取红茶成品，对该成品进行吡虫啉含量进行检测。数据判定:若铅实测值不大于0.5mg/L，则该成品为合格，w=（A1×V1×V3×ρ）/(A2×V2×V4×m）：w为试样中吡虫啉的含量，mg/L，A1为试样中组分的峰面积或峰高，V1为试样中提取的总体积(ml)，V3为浓缩后甲醇定容体积(ml)，ρ为标准溶液中吡虫啉质量浓度(mg/L)，A2为标准样中组分的峰面积或峰高，V2为净化用提取液的总体积(ml)，V4为进样体积(μL),m为试样称样量，g。

This dataset is developed based on sampling and testing of black tea products produced by our company, with the detection item being imidacloprid content. Imidacloprid content is a critical indicator for the food safety of black tea, providing factual evidence for the quality analysis and evaluation of black tea.

Data Collection: Finished black tea products are randomly sampled, and the imidacloprid content of each sampled product is detected.

Data Judgment: A finished black tea product is considered qualified if its measured lead content is no more than 0.5 mg/L. The calculation formula for imidacloprid content in the test sample is:
$$w = frac{A_1 imes V_1 imes V_3 imes
ho}{A_2 imes V_2 imes V_4 imes m}$$
Where:
- $w$: Imidacloprid content in the test sample, unit: mg/L
- $A_1$: Peak area or peak height of the target component in the test sample
- $V_1$: Total volume of the extract from the test sample, unit: mL
- $V_3$: Constant volume of methanol after concentration, unit: mL
- $
ho$: Mass concentration of imidacloprid in the standard solution, unit: mg/L
- $A_2$: Peak area or peak height of the target component in the standard sample
- $V_2$: Total volume of the extraction solution for purification, unit: mL
- $V_4$: Sample injection volume, unit: μL
- $m$: Mass of the sampled test specimen, unit: g
