TANGO. ANALYSIS TO GO. The next generation FT-NIR spectrometer.

Importance of the Topic

Near-infrared spectroscopy (NIR) plays a critical role in modern industrial quality control and process analytics. Its ability to deliver rapid, non-destructive measurements supports high sample throughput and real-time decision-making across sectors such as food, feed, pharmaceuticals, chemicals and polymers. The introduction of an easy-to-use, robust FT-NIR instrument reduces operator training demands and enhances data reliability, meeting the stringent requirements of regulated environments.

Objectives and Study Overview

This summary describes the next-generation TANGO FT-NIR spectrometer designed for industrial use. The study aims to demonstrate how TANGO delivers faster measurements, intuitive operation and seamless calibration transfer while maintaining high precision and stability under varying environmental conditions.

Methodology

TANGO applies Fourier transform near-infrared spectroscopy with interchangeable modules for transmission (liquids) and diffuse reflection (solids). Key workflow features include automated background scans, one-step sample loading into cups or vials, preconfigured application icons or barcode selection and single-touch measurement initiation. Temperature-controlled liquid analysis is realized via an integrated heater/cooler spanning 20–80 °C.

Instrumentation Used

• FT-NIR spectrometer with cube-corner interferometer for exceptional optical path stability
• Gold-coated integrating sphere for reproducible diffuse reflection measurements
• Active sample heater/cooler unit with continuous temperature monitoring
• Internal validation module for automatic performance checks
• Touch-screen interface integrated with onboard PC or external laptop connectivity
• Automated background management and direct calibration transfer via LAN or USB

Main Results and Discussion

TANGO achieves rapid measurement cycles of 15–30 seconds per sample, minimizing bench time and labor costs. Its compact footprint and 360° operability allow flexible lab or at-line placement without sacrificing ease of cleaning or maintenance. Automated calibration transfer ensures reproducible results across instruments and sites, boosting inter-instrument consistency. The touchscreen interface, available in 17 languages, guides operators step-by-step, reducing user errors and eliminating specialized training requirements.

Benefits and Practical Applications

TANGO’s combination of precision, speed and simplicity supports:

• Incoming raw material verification
• In-process monitoring and process‐accompanying analytics
• Final product inspection and release testing
• Quantitative analysis of moisture, fat, protein and other components

Typical industries benefiting from TANGO include food and beverage, feed manufacturing, pharmaceuticals and biotechnology, chemical and petrochemical production, and polymer processing.

Future Trends and Applications

Advancements in chemometric modeling and cloud-based analytics will enhance remote monitoring and predictive process control. Integration with Internet of Things (IoT) platforms can enable real-time data sharing and automated corrective actions. Continued miniaturization and ruggedization may expand FT-NIR use into field and point-of-care settings.

Conclusion

The TANGO FT-NIR spectrometer represents a major step forward in industrial spectroscopy by combining high analytical performance with user-friendly operation and efficient calibration management. Its robust design, fast throughput and application-specific configurations position it as a versatile tool for quality assurance and process optimization.
