Specialized protocols are available for different applications:

• QGA: Measures cellular ATP in water samples by filtration and cell lysis.
• QG21S: Designed for products such as paints, adhesives, slurries or detergents, involving dilution, extraction, and measurement of total and dissolved ATP.

Building on the ATP test method, the Biomass Stress Index (BSI) can also be determined. BSI is calculated as the ratio of extracellular ATP (from dead or stressed cells) to total ATP, providing a clear picture of biomass stability. As a key parameter for monitoring microbial health in wastewater and other systems, BSI helps operators quickly detect stress, evaluate microbial balance, and take corrective actions to maintain efficient and stable treatment processes.

Advantages of the ATP-Test

• Rapid: Provides real-time, actionable results within minutes, enabling immediate decision-making (unlike traditional dip slides or culture-based methods, which can take several days).
• Quantitative and precise: Converts raw light measurements into ATP concentration (pg per mL), allowing accurate, comparable analysis across samples.
• Versatile: Different testing kits are available to suit a wide range of samples, from water, raw materials to finished products.
• Sensitive and reliable: Detects low microbial loads and removes possible interferences.
• Cost-efficient: Reduces the need to traditional cultural-based methods.
• Portable and easy to use: Equipment can be used on-site and fits into routine hygiene checks.
• Complementary to traditional methods: While the ATP test is excellent for rapid, quantitative monitoring, traditional laboratory-based culture methods are still required for detailed qualitative analysis.

Various Industrial Applications

The ATP test is widely applicable across industries:

• Water systems: Monitoring microbial contamination in cooling towers, boilers, and tanks.
• Biofilm detection: Identifying hotspots in tubing, filters, and pumps before contamination spreads.
• Production environments: Verifying cleanliness of raw materials, semi-finished goods, and production equipment.
• Biocide optimization: Measuring treatment efficiency, adjusting dosage, and reducing chemical overuse.

By integrating ATP monitoring, users can improve microbial control while lowering costs and reducing environmental impact.

Customer Success Stories

Customers who have used IMPAG’s ATP testing service consistently praise its speed, accuracy, and practicality:

• Adhesives manufacturer: The ATP test confirmed in under 2 hours that a newly developed conservation system (introduced in several formulation) was robust enough to ensure shelf-life, enabling a safe market launch.
• Chemical raw material manufacturer: Previously relying on dip slides, which required several days for lab results, this customer was impressed to receive numerical data within 10 minutes. Initial analysis revealed contamination in the red zone. After adjusting the biocide dosage and retesting the next day, the microbial load was reduced to zero. The method’s efficiency was so convincing that the customer is now considering acquiring their own device.
