VideometerLiq: Advancing Spectral Liquid Analysis for Quality Control

In industries where liquid performance defines product success, from food and beverages to cosmetics, coatings, and pharmaceuticals, accurate, non-destructive liquid characterization is critical. Subtle shifts in formulation, stability, or microstructure can impact texture, color, shelf life, regulatory compliance, and customer satisfaction. Yet conventional analytical workflows often rely on dilution, manual inspection, or subjective assessments, resulting in inconsistent data and delayed decision-making.

The VideometerLiq changes this paradigm. Purpose-built for advanced spectral liquid analysis, it delivers objective, high-resolution insights into the physical and chemical properties of liquids, without destroying samples or altering their composition.

The Growing Need for Advanced Liquid Characterization

LLiquids are highly dynamic systems. Small deviations in:

• Particle size distribution
• Chemical composition
• Homogeneity and phase separation
• Optical and absorbance properties
• Structural stability over time

may evolve into product failure, sedimentation or discoloration. Traditional testing methodologies often detect problems too late, after shelf-life instability is visible or batches have already been shipped.

Modern industries demand reproducible, quantitative, and traceable measurements to support formulation, approval, and ongoing quality control. The VideometerLiq provides exactly that.

What Is the VideometerLiq?

The VideometerLiq is a multispectral imaging instrument engineered specifically for liquid analysis and stability monitoring. Built on the VideometerLab, it illuminates samples using 20 wavelengths, from UV to near-infrared, to generate precise spectral signatures that reveal microstructural and chemical variations invisible to the human eye.

The instrument uses:

• Diffuse frontlight illumination from 365 nm UV to 970 nm NIR
• Brightfield NIR backlighting for enhanced contrast
• High spatial resolution at 0.030 mm/pixel

This allows customers to perform non-destructive evaluation of undiluted liquid samples directly in bottles, ensuring results reflect true product behaviour, not altered lab artifacts.

Scientific Principle Behind Multispectral Liquid Analysis

Multispectral imaging creates a spectral fingerprint for each liquid by measuring reflectance across multiple wavelengths. These fingerprints quantify:

• Color changes and oxidative reactions
• Phase separation and sedimentation
• Structural formation of bubbles or particles
• Heterogeneity distribution across height and volume

Unlike manual microscopy, this method does not require:

• The use of reagents
• Sample manipulation
• Operator interpretation

Instead, the output is a standardized, objective dataset ready for R&D, QC documentation, and regulatory audits.

Real Industry Examples

The VideometerLiq offers insight far beyond visual assessment, as demonstrated in multiple real-world applications:

Emulsion Stability and Bubble Characterization

Spectral imaging highlights instability patterns, microbubbles, and dispersed particulates that precede full separation, long before the product looks compromised to the naked eye.

This empowers formulators to optimize surfactants, emulsifiers, and processing parameters with measurable data.

Chocolate Milk: Detecting Marbling and Cream Separation

The system tracks reflectance changes along the sample, quantifying marbling patterns and cream formation over shelf life.

It can also differentiate temperature-dependent stability shifts, essential for cold-chain validation in dairy production.

Yoghurt Syneresis

The instrument quantifies whey separation, producing percentage syneresis instantly.

This eliminates manual measurement variability and accelerates product development cycles.

Key Advantages of VideometerLiq in Industrial and Research Applications

• Non-destructive testing – maintain product integrity
• Objective, reproducible data – eliminate operator bias
• Multispectral precision – uncover hidden structural and chemical variations
• Direct measurement – analyse liquids without dilution
• Real-time analytics – accelerate decision-making and reduce rework
