NIR spectral of 8 types of commodities in different environments

This dataset contains spectra of 8 types of commodities collected from two different environments. The dataset can be used to study the impact of scanning environments on the spectra distortionFor each type of commodity, the dataset also provide spectra collected from contaminated samples. The contamination was introduced by using an eye dropper to add one drop of the solutions (water, saturated brine, or olive oil) to the normal samples. The amount of solution for each drop is around 0.04ml to 0.05ml. For each commodity, 9 samples were contaminated: 3 with water, 3 with saturated brine, and 3 with olive oil.Commodities include:1 coffee pods,2 magnesium effervescent tablets,3 vitamin C effervescent tablets,4 paracetamol,5 panadol,6 IbuprofenEG7 aspirin8 magnesium B6

本数据集收录了自两种不同环境中采集的8种商品的光谱数据。该数据集旨在研究扫描环境对光谱失真的影响。针对每种商品，数据集还提供了从受污染样本中收集的光谱数据。污染通过使用滴管向正常样本中滴加一滴溶液（水、饱和盐水或橄榄油）而引入。每滴溶液的量约为0.04毫升至0.05毫升。对于每种商品，共进行了9个样本的污染实验：其中3个样本添加了水，3个样本添加了饱和盐水，3个样本添加了橄榄油。商品种类包括：1. 咖啡胶囊；2. 镁碳泡腾片；3. 维生素C碳泡腾片；4. 对乙酰氨基酚；5. 潘妥洛克；6. 伊布普罗芬；7. 阿司匹林；8. 镁B6。
