Description of Gastec PD-1B-2 Permeater
PD-1B-2 Gastec A fluoro resin tube that holds premium liquefied gas is called a permeater permeation tube.
A certain amount of gas can be held in the tube by osmosis, which allows liquefied gas to enter the tube wall in time increments when the tube is exposed to a particular temperature. As a result, by maintaining the tube at a fixed temperature and injecting a consistent amount of dilution gas, a carrier gas flowing at a constant speed (for calibration purposes) can be constantly formed.
Because the concentration of the calibration gas is calculated by measuring the amount of dilution gas and the change in weight of the permeation tube, this approach is very dependable. Highly reactive gases including ammonia, hydrogen sulfide, and chlorine can also be produced using this dynamic approach. There are numerous varieties of permeation tubes, as the table below illustrates, and they are frequently utilized due to their capacity to deliver a consistent supply of calibration gas.
Features of Gastec PD-1B-2 Permeater
- Highly reliable because concentration levels are determined by calculating weight loss based on.
- Many types (both organic and inorganic) of low-concentration calibration gases) can be generated.
- Gas for calibration of all organic solvents (as long as they are stable in their liquid state or at normal temperatures) can be generated.
- Gas for calibration can be generated continuously for longer periods of time.
- Calibration gas can be easily generated in a wide range of concentrations.
Specification of Gastec PD-1B-2 Permeater
| Target gas to be generated | Permeation tube method: As a characteristic of the gas, the boiling point ranges between -60 and +30?. In addition, the stable, high-purity material used for the permeation tube enables the calibration gas to be generated. Diffusion tube method: As characteristics of the liquid, the vapour pressure over the temperature range of 25-50? lies within the range of 5-400 mmHg. In addition, the stable, high-purity material used for the permeation tube enables calibration gas to be generated. |
