FBA 5320 Laboratory Fluorinated By-Products Analyzer

Accurately quantify total fluorinated contaminants in the low parts-per-million (ppm) range in liquid propane or liquid butane process stream samples with OI Analytical’s FBA 5320.


The OI Analytical FBA 5320 is a laboratory fluorinated by-products analyzer (FBA) designed to quantify total fluorinated contaminants in samples from liquid propane or liquid butane process streams. The analyzer is based on an Agilent 7890 gas chromatograph (GC) equipped with an automated liquid sampling valve for sample introduction, a packed-inlet injection port, a stainless steel column, and 5320 Electrolytic Conductivity Detector (ELCD) configured for fluoride detection. The FBA 5320 accurately detects total fluoride concentrations in the low parts-per-million (ppm) range.

General Specifications  
Operating Principle Fluorinated compounds eluting from a GC column are catalytically reduced in a high temperature micro-reactor and converted to HF gas. The HF gas dissolves in a deionized solvent increasing the electrolytic conductivity of the mixture. The change in conductivity is directly proportional to the mass of fluoride in the sample.
