FTIR Analyzer Lyza 5000 Wine

Importance of the Topic

Rapid and reliable analysis of must and wine is crucial for ensuring quality, optimizing fermentation, and maintaining consistency across production cycles. FTIR spectroscopy provides a non-destructive, multi-parameter approach that accelerates decision-making in both small wineries and large-scale operations.

Objectives and Study Overview

The primary goal is to present the Lyza 5000 Wine FTIR analyzer as a comprehensive solution for real-time measurement of fermentation must, must in fermentation, and finished wine. This overview highlights its performance, usability, and integration capabilities.

Methodology and Instrumentation

The Lyza 5000 Wine employs a precisely temperature-controlled 12-bounce ATR flow-through cell made of germanium, combined with a hermetically sealed FTIR spectrometer and a pyroelectric DLaTGS detector. Calibration models for ethanol, sugars, acids, and other key analytes are preloaded. Automated reference routines use water and ethanol measurements, eliminating the need for proprietary standards.

Used Instrumentation

• Lyza 5000 Wine FTIR analyzer with 12-bounce ATR cell and Peltier temperature control.
• Xsample 370 sample changer for automated filling, cleaning, and drying.
• Xsample 520 for high-throughput analysis (up to 48 samples).
• Anton Paar density, alcohol, pH, and turbidity meters for expanded parameter sets.

Main Results and Discussion

The Lyza 5000 Wine delivers results in under one minute for over 15 analytes, including ethanol (0–20 %v/v), glucose and fructose (up to 160 g/L), titratable acidity (2–15 g/L), volatile acids (up to 2.5 g/L), malic and lactic acids, glycerol, and more. Repeatability typically falls within 0.01–0.4 units depending on the parameter. The instrument’s stability is maintained by controlled temperature (±0.03 °C) and a desiccated spectrometer core.

Benefits and Practical Applications

• Fast, multi-parameter analysis streamlines quality control and fermentation monitoring.
• No need for chemical reference standards reduces consumable costs.
• Flexible operation modes: standalone, automated, or integrated with existing lab equipment.
• Seamless data handling via touchscreen, digital export, and LIMS connectivity.

Future Trends and Opportunities

Advances in chemometric calibration, machine learning algorithms, and cloud connectivity will enhance predictive analytics and remote monitoring. Continued miniaturization and integration may lead to portable or inline FTIR solutions for vineyard and winery process control.

Conclusion

The Lyza 5000 Wine FTIR analyzer combines speed, accuracy, and versatility for comprehensive wine analysis. Its robust design, automated workflows, and connectivity options make it an invaluable tool for modern enology and quality assurance.
