Cerveza NIR Column

Database composed of about 264 measurements of over 50 beers made with a spectrophotometer. For taken the measures, some quartz cells have been used. In order to be able to generate the database properly, the variability in temperature has been taken into account. For this reason, the temperature conditions under which they were taken are identical, 8º C. To perform the capture, a DLPNIRNANOEVM rev. G has been used as spectrophotometer. This device has an operational range between 900 nm and 1700nm. Using a Hadamard and a Column analysis, the measures has taken 228 reference points to capture the intensity, absorvance, relfectance, wavelength and the tiem of measurement for each of the aforementioned points. Labels indicate the type of analysis and the beer's alcoholic strength.本数据库由约264次使用分光光度计对超过50种啤酒进行的测量组成。为进行测量，使用了部分石英细胞。为确保数据库的准确构建，已充分考虑温度的变异性。因此，所测量的温度条件保持一致，均为8℃。 为执行捕捉，采用了型号为DLPNIRNANOEVM rev. G的分光光度计。该设备的工作波长范围为900 nm至1700 nm。通过哈达玛德分析和列分析，对每个测量点进行了228个参考点的捕捉，以获取强度、吸光度、反射率、波长及测量时间。标签表明了分析类型及啤酒的酒精度。
