TVA-1000 Rental or Buy
The TVA-1000 is a portable Flame Ionization Detector (FID) featuring an optional photoionization (PID) detector. It features multiple response factors and curves, multi point calibration, on board datalogging and an 8 hour battery life. These features combined in a portable and lightweight package have made the TVA-1000 our most popular FID.
Introduction to FIDs
A Flame Ionization Detector (FID) measures real time concentrations of volatile organic compounds (VOCs) in low levels from parts per billion (ppb) up to 50,000 parts per million (ppm).
Unlike a Photoionization Detector (PID), which uses a high energy ultra violet light to ionize molecules, anFID ionizes samples by burning them with a hydrogen flame. This method can ionize any organic compound with an ionization potential (IP) of 15.4 or lower. Ions formed in the sample stream are driven in one direction by a bias electrode and accumulated at a collector electrode. The ion current is then amplified and converted to a meter readout in parts per million (ppm).
