Many analyzers claim to measure in the low ppb range but it can be difficult to verify that an online instrument is accurately reading at this low-level. Part-per-billion standards are difficult to make and maintain, and transporting grab samples for laboratory analysis is difficult.
Product Detail
The low-level verfication system uses online dynamic dilution. The key component of this system is the dynamic syringe pump which can deliver a steady flow rate of solution or standard down to 0.1 mL/min. The low-level verfication kit includes an injection port, which is installed into the process downstream of flow regulation.
The expected reading is the sample reading plus the expected standard concentration.
