Rapid, unambiguous materials qualification without the need for expert knowledge of chemometrics using this FT-IR and FT-NIR spectroscopy materials checking system
PerkinElmer's Spectrum AssureID materials checking system utilises FT-IR and FT-NIR spectroscopy to generate sample-specific 'fingerprints' of production materials. Acceptance thresholds are established by measuring samples that define the potential quality limits of each raw material.
Once a database of typical samples has been created for each material, AssureID can employ Compare and Simca (Soft Independent Modelling Class Algorithm), to classify new samples.
The software provides fast data modelling, troubleshooting and method validation and is fully 21CFR part 11 compliant.
A new application note describes and illustrates the quality control of raw materials of a nutraceutical product using AssureID.
Three components were qualified: acesulfame, aspartame, and ascorbic acid.
Fifteen spectra of each compound were collected, using the Spectrum One NTS and Nira accessory.
Six samples for acesulfame and aspartame and five each for two ascorbic acid types were used for building the model, and the others for validating the method.
A series of unidentified samples were processed using the model, and all were correctly identified.
AssureID provides rapid, unambiguous materials qualification without the need for expert knowledge of chemometrics.
Use of the Simca classification algorithm increases the robustness of methods by taking account of batch-to-batch and sampling variations in a model-based approach.
In the example given, all the different materials were clearly identified and qualified as suitable for use
