Choosing the correct ATP test kit is essential for obtaining accurate and meaningful microbial data. Your choice depends on the sample type, environment, and specific characteristics of the material being tested. LuminUltra provides two core LifeCheck ATP kits to meet diverse testing needs:
LifeCheck ATP Test Kits
1. Planktonic Kit
- Designed for liquid samples where microbes are free-floating (referred to as “planktonic”).
- Ideal for testing water, production fluids, brines, emulsions, and other water-based liquids.
2. Sessile Kit
- Designed for solid or surface samples where microbes are immobile (referred to as “sessile”).
- Tailored for biofilms, corrosion sites, scale, viscous fluids, and solid surfaces.
- Includes multiple testing procedures to suit different sample characteristics:
- Solids Soak Test: Ideal for solids or scrapings like scale and corrosion product.
- Solids Swab Test: Designed for surfaces such as corrosion coupons, equipment sites, or pipelines.
- Viscous Fluid Test: Optimized for heavy, gel-like, or viscous samples such as fracturing fluids, pigging sludge, and heavy oils.
Factors to Consider When Choosing a Kit
1. Sample Type
- Planktonic Kit: Use for water-based or liquid samples.
- Sessile Kit: Use for solids, surfaces, biofilms, viscous fluids, or oil-based samples.
2. Sample Characteristics
- Viscous Fluid Test : For fluids difficult to filter, such as viscous or gel-like substances
- Solids Soak Test or Solids Swab Test: For corrosion coupons or scale scrapings.
3. Volume and Surface Area
- Liquids: Typically require 10–60 mL of sample.
- Solids: Require at least 5 grams of material.
- Surfaces: A minimum surface area of 10–25 cm² (about 1-2 square inches) ensures reliable results.
Common Scenarios and Test Kit Recommendations
When testing complex or unique fluids, refer to the selection chart below for guidance. Always prioritize the Planktonic Test when possible, as its results offer the highest accuracy and consistency.
