Assay Range as TPH: range varies based on fuel source.
- Soil: 0.9 ppm to 30 ppm as Total BTEX Standard
- Water: 0.02 to 3.0 ppm as Total BTEX Standard

Sampling Time
- Soil extraction time is typically 2 minutes per sample plus assay run time of approximately 60 minutes.

Test Kit Components
- Antibody coated magnetic particles for analysis of 30 or 100 test tubes
- Diluent zero, wash, enzyme conjugate, color development and stop reagents
- Standards for 0.09, 0.35 and 3.0 ppm as Total BTEX
- Kit Control at 2.1 ppm as Total BTEX
- Disposable test tubes
- Test kit instructions

Storage & Precautions
- Shelf life is typically one year from date of manufacture, with specific kit expiration date information provided on product packaging.
- Reagents must be stored at 39 to 46F (4 to 8C) when not in use.
- Storage at ambient temperature 64 to 81F (18 to 27C) is acceptable for day of use.
