Software
The MicroNIR OnSite-W system includes the MicroNIR Pro software suite with features for data acquisition, calibration and method development, user management, and real-time prediction. Using MicroNIR Pro software, a developer can process data and build complete chemometric models using regression and classification algorithms including PLS, MBSD, SMV, and PCA analyses. Batch mode predictions on stored data are also supported. MicroNIR Pro software also includes instrument performance qualification per EP 2.2.40 and USP 1119 test criteria and tools enabling Title 21 CFR Part 11 compliance. An enhanced OPC interface is optionally available for integration with process control systems. The OnSite-W system also includes a standalone tablet application with simplified user interface for data acquisition and real-time prediction in the field. Please see recommended hardware/software listed in specifications.
