Versatile 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.

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.
