Product Certificate for Spectrum Two N
NIR Spectroscopy is a useful technique for raw materials identification and verification, but the sophistication of the technique might differ based on the sample. If the materials to be identified are spectroscopically dissimilar, it is often only necessary to use a simple distance measure such as a spectral difference for identification. If the spectra are similar, on the other hand, it may be necessary to use more sophisticated techniques which take into consideration both the intra- and inter-material spectral variation for identification and classification. The SIMCA (Soft Independent Modelling of Class Analogy) algorithm, a Principal Component Analysis (PCA) method, provides such an example.
Herbal lifestyle products are widely used as alternatives to medicines around the world, with as many as 80% of people using them as a primary source of healthcare in developing countries. These treatments are commonly regarded by scientific papers, and on some occasions the media, as being inferior to orthodox treatment. This is due to the variation between herbal formulations which will not be present in so called ‘single-chemical’ drugs. The reasons for the aforementioned variation involve several factors including storage, environmental conditions, handling and unintentional or intentional contamination (adulteration).
The exact number of counterfeit medicines produced/consumed each year is difficult to determine due to the usually illegitimate methods by which they are distributed. However, the scale of the problem can be represented by the fact that 20 million pills, bottles, and sachets of counterfeit medicines were seized in a five-month operation conducted by the International Criminal Police Organization in China and South-East Asia.
主要介绍在符合 21 CFR 第11部分的规定的前提下，利用 PerkinElmer Spectrum Two N™ FT-NIR 近红外分光光谱仪，建立符合数据完整性规程的测试模型，从而克服原材料测试过程中的多重挑战。
Near-infrared (NIR) spectroscopy is an important technique for materials checking at various stages of the manufacturing process, but is particularly useful at the raw materials inspection stage. Raw materials come in a variety of physical forms including liquids, gels, and solids, requiring a versatile instrument with convenient, interchangeable sampling modules to cater to the entire range of raw materials encountered.
本次应用研究，使用傅立叶变换近红外光谱仪（FT-NIR）测定棕榈油和其他食用油产品中的固体脂肪含量（SFC）。结合PLS 校准方法和FT-NIR 光谱法，分别测试样品在10℃、20℃、25℃、30℃和35℃下的固体脂肪含量，建立近红外（FT-NIR）测试脂肪中固体脂肪含量的方法。
幸运8平台彩票由于测试过程的快速和无损，近红外（NIR）光谱是一种很有吸引力的粉末物质中掺杂物的筛查工具。 近红外光谱并不适合于检测成品中如此低含量的三聚氰胺，但是非常适合于筛查原材料。 相比于在成品中检测出三聚氰胺，如果在原材料中检测出三聚氰胺则更容易追查其来源。
幸运8平台彩票Infrared (IR) and near-infrared (NIR) spectroscopy are fast, easy-to-use techniques with a history of being used for food applications such as those for measuring protein, moisture, and fat content. Food fraud and adulteration has become of particular concern to the industry over the past few years following reports of incidents in the media, with herbs and spices identified as one of the key problem areas.
