Distinction given as under
Explanation:
- Photoionization detectors (PID) and Flame Ionization detectors are sensitive low range gas vapor instruments that are optimized to detect different gases.
- An FID is larger and heavier than PID, it used the ionized frame to ionize sample gas, to determine its concentration. However its less cost and less reliable than PID.
- FIDs are generally not impacted by humidity, so they may be a better choice than PIDs for this type of climate. Fid produce very different rating than Pid.
- FID cannot detect organic substances., and its flame oxidizes all oxidants that pass through it. Its advantage isit cost and low maintains as compared to others.
