NIR spectroscopy is a fast non-destructive analytical method. Almost any kind of sample can be scanned within seconds with minimal or even no preparation at all. NIRS can verify the identity of a sample and quantify multiple chemical and physical properties simultaneously.

Research and quality control laboratories benefit from NIRS alike. While researchers can accelerate their experimentation, QC departments benefit from the ability to analyze hundreds of samples per day – both saving substantial amounts of time and money.

While the number of parameters measurable within a calibration model is only limited by computing power and complexity of the analysis, it is common to analyze 15-30 properties at the same time.

Generally speaking, high throughput can be achieved by a short sequence of multiple samples or by a high degree of parallelization. Dumas runs in a rapid sequential mode whereas Kjeldahl is slower, but digests 20 samples at once. This results in a comparable throughput over a working day as digestion and distillation of subsequent batches are carried out simultaneously. With an NIR instrument, results are obtained in 30 – 60 seconds. Manual sample changing is the limiting factor for an increased throughput.

In many matrices fat is naturally encased or chemically bound. Therefore, hydrolysis is required to transform lipids into extractable forms. Hydrochloric acid disrupts cells walls, hydrolyses proteins / polysaccharides, and breaks lipid-carbohydrate bonds.
