FTIR Analyzer Lyza 5000 Wine

Importance of the topic

The control of wine production processes demands rapid, reliable, and comprehensive analytical methods to guarantee consistent quality and optimize resource use.
Real-time monitoring of must, fermentation, and finished wine allows winemakers to adjust parameters such as sugar levels, acidity, and alcohol content precisely.

Study objectives and overview

This document presents the Lyza 5000 Wine, a novel multiparameter FTIR analyzer designed for streamlined measurement of must, must in fermentation, and wine.
Key goals include:

• Delivering results for over 15 critical parameters in under one minute.
• Providing ready-to-use calibration models for must, fermenting must, and wine matrices.
• Enabling standalone operation or integration with automation devices and existing Anton Paar instruments.

Methodology and instrumentation

The Lyza 5000 Wine applies Fourier-transform infrared spectroscopy with a 12-bounce attenuated total reflection (ATR) cell made of germanium.
Temperature control is achieved via a Peltier element, ensuring stability within ±0.005 °C.
A hermetically sealed spectrometer core houses a permanently aligned interferometer with KBr beam splitter and gold-coated mirrors, coupled to a DLaTGS detector.
Reference measurements use water as a baseline; no proprietary standards are required thanks to the patented Cleaning Performance Index.

Instrumentation used

• Lyza 5000 Wine FTIR analyzer with 10.1" PCAP touchscreen.
• 12-bounce ATR Ge flow-through cell.
• Xsample 370/520 automated sample changers for up to 48 samples.
• Optional integration with Anton Paar density, alcohol, pH, and turbidity meters.
• Communication via USB, RS-232, CAN, Ethernet, and external Wi-Fi dongle.

Main results and discussion

The analyzer quantifies parameters including ethanol (0–20 %v/v), sugars (glucose, fructose, sucrose up to 160 g/L), acids (titratable, volatile, malic, tartaric, lactic, gluconic), glycerol, density, pH, extract, polyphenols, and yeast assimilable nitrogen.
Repeatability is high (e.g., ethanol ±0.02 %v/v, density ±0.0001 g/mL), and measurement time per sample is approximately 31 seconds after temperature equilibration.
Integration of multiple instruments into a single workflow reduces sample preparation steps and delivers consolidated reports.

Benefits and practical applications

The Lyza 5000 Wine enables winemakers and quality laboratories to:

• Perform high-throughput analysis without consumable references.
• Monitor fermentation kinetics and adjust parameters in real time.
• Ensure compliance with regulatory and quality standards through reliable data.
• Automate workflows and integrate results into LIMS systems.

Future trends and potential applications

Advancements may include:

• Enhanced chemometric models using machine learning for improved prediction accuracy.
• Extension of methodology to related beverages, juices, and food matrices.
• IoT connectivity and cloud-based data analytics for remote monitoring.
• Miniaturized or portable FTIR platforms for field or in-cellar use.

Conclusion

The Lyza 5000 Wine FTIR analyzer offers a robust, fast, and versatile solution for comprehensive wine analysis.
Its automation capabilities, broad parameter coverage, and ease of integration position it as a valuable tool for modern oenological quality control and research.
