Abstract

The invention belongs to the field of near infrared modeling, and particularly relates to a method for improving the quality of near infrared modeling prediction ability. A near infrared spectrum is collected for multiple times to carry out average calculation, an optimal point for average processing is found, and subsequently, a PLS (Principal Component Analysis) model is established. For a spectrum of a raw material human plasma sample, each sample should collect and average 11 spectrums to obtain the relatively stable NIR (Near Infrared), and then, each sample participates in NIR modeling.A spectrum modeling comparison result proves that the near infrared model established in the invention is obviously superior to a common NIR modeling method and has an important application value in the detection of the total protein content of the raw material human plasma of a blood product.

Description

technical field

[0001] The invention belongs to the field of near-infrared spectroscopy modeling, and in particular relates to a method for improving the modeling and prediction ability of near-infrared spectroscopy technology based on "data averaging". Background technique

[0002] Near Infrared (NIR) is an electromagnetic radiation wave between visible light (Vis) and mid-infrared (MIR). The first non-visible region discovered in the absorption spectrum has applications in pharmaceuticals, medical diagnostics, quality control of food and agricultural products, astronomy, and therapeutic medicine.

[0003] Quantitative analysis of near-infrared spectroscopy is a secondary analysis method. The analysis process is as follows: use a near-infrared spectrometer to measure the near-infrared spectrum of a sample; use a standard reference method to measure the concentration or property reference value of a specific component in the sample; Data and concentration or property refere...
