Visum Palm™ - Handheld NIR Analyzer for Real-Time Quality Control
Portable handheld NIR analyzer with benchtop mode for lab-quality analysis in production, warehouse, field and laboratory environments. Results in 3 seconds with no sample preparation.
REQUEST A QUOTEVersatile Multi-Parameter Analysis
The Visum Palm™ is a self-contained, easy-to-use handheld NIR analyzer designed for real-time chemical composition analysis and faster quality control decisions across food, feed, plastics, pharma and other industrial applications.
Available in both standard industrial and GxP-compliant versions, it adapts to routine quality control as well as highly regulated environments requiring maximum traceability and compliance.
Laboratory-Quality Results Anywhere
Its true dual functionality combines handheld and benchtop operation in a single self-contained device, enabling stable, repeatable and on-site analysis with full operational autonomy. High spectral resolution (5 nm), low instrumental noise and an efficient optical design deliver laboratory-quality precision and repeatability for critical applications.
User autonomy is a key advantage. With the automatic Model Builder in Visum Master™, users can easily create and update calibrations, identification libraries and quantitative methods without advanced chemometrics expertise or dependence on external support.
Applications of the Visum Palm™ handheld NIR analyzer span food and feed quality control, agricultural raw material analysis, forage and mixture evaluation, plastics and textile identification, and other industrial uses requiring fast and reliable on-site results.
For regulated environments, the GxP version is especially suited to pharmaceutical applications such as raw material identification (RMID), loss-on-drying (LOD) analysis, and quantitative assays of APIs and excipients, including product release workflows.
Main features
All key functions can be performed directly from the device interface, including batch identification or barcode reading, analysis selection, real-time results and spectra visualization, measurement history access, configuration settings and user management.
For regulated environments, the GxP version incorporates advanced features such as Audit Trail, electronic signature, operation validation, instrument qualification assisted by reflectance standards, and specific configurations for CFR and GMP compliance.
By simply inputting spectra and reference data (quantitative or qualitative), users can generate robust calibrations without prior expertise in spectroscopy or chemometrics.
This enables quality control teams to create, update and maintain their own NIR methods with full autonomy, eliminating technical barriers and reducing reliance on external support.
It includes benchtop sample holders for granules, powders and solids, as well as dedicated accessories for liquids, including reusable or disposable cuvette and vial holders.
Additional accessories include an optical flattener for direct analysis through translucent packaging, eliminating the need to open or handle the sample, and an optical reducer for small samples, tablets and limited measurement areas.
Why is Visum Palm™ the best handheld NIR analyzer?
-
Autonomous analyzer: A fully integrated handheld NIR analyzer with embedded computer, touchscreen and onboard software, eliminating the need for smartphones, tablets or external devices. This enables practical use in production, laboratory and field environments and, in GMP settings, simplifies operational qualification and validation workflows.
-
Dual functionality: The only handheld NIR analyzer that easily switches between handheld, portable and benchtop modes, adapting to different analytical needs and working environments.
-
AI-assisted software: The integrated Model Builder in Visum Master™ allows users to develop and update NIR calibrations and libraries without advanced expertise in spectroscopy or chemometrics.
-
Superior signal-to-noise ratio: With a signal-to-noise ratio of 4500:1, it significantly outperforms other portable analyzers on the market and exceeds USP requirements for critical pharmaceutical applications.
-
Calibration and library transfer: Enables migration, adaptation and reuse of existing calibrations and libraries from other analyzers widely used in the industry, reducing implementation time and avoiding the need to start from scratch.
-
Regulatory compliance: The GxP version complies with 21 CFR Part 11, USP 1119, PE 2.2.40 and JP18, as well as GMP and GAMP 5 guidelines, making it ideal for regulated environments.
-
Highest spectral resolution: Offers 5 nm spectral resolution and 256 spectral channels, between 2 and 4 times better than other handheld NIR analyzers on the market.
