Total Migration and Non-Volatile Residue Constant Weight Analyzer
Release time:
2025-12-05
This instrument is primarily known as a Total Migration and Non-Volatile Residue Constant Weight Analyzer or a specialized High-Precision Gravimetric System for Overall Migration Testing.
It is a crucial tool in quality control and safety assessment for food contact materials (FCMs).
Overall Migration (OM) and Non-Volatile Residue (NVR) Tester
Introduction
This system is designed to determine two critical safety parameters of materials intended to come into contact with food:
Overall Migration (OM) / Total Migration: The total amount of all non-volatile substances that migrate from a food contact material into a food simulant under defined test conditions (time and temperature). This value is regulated globally to ensure consumer safety.
Non-Volatile Residue (NVR) / Constant Weight Measurement: The precise determination of the mass of residue remaining after evaporating a solvent or food simulant to a constant weight. This gravimetric technique is the core of the Overall Migration test.
International Standards Compliance
The testing procedures performed by this equipment must strictly adhere to international and regional regulations for food contact materials. Key standards include:
European Union (EU): Regulation (EU) No 10/2011 (and amendments) on plastic materials and articles intended to come into contact with food. This regulation strictly defines the Overall Migration limits and test conditions.
United States (US): FDA 21 CFR (specific sections regarding extraction and migration testing).
General Gravimetric Standards: The methodology often aligns with procedures outlined in standards such as EN 1186 Series (for Overall Migration) and ISO 6483.
Applications
The analyzer is indispensable for manufacturers and regulatory bodies across various sectors:
Food Packaging: Testing films, rigid containers, seals, adhesives, and coatings (plastics, paperboard, multilayered composites).
Utensils and Appliances: Assessing the safety of kitchenware, cutlery, and components of food processing equipment.
Baby Products: Ensuring migration safety for bottles, pacifiers, and related feeding accessories.
Quality Control (QC) & Research and Development (R&D): Used to screen new materials, monitor production quality, and certify compliance with national and international health and safety regulations.
