GASTEC P-73-H Permeation Tube Dimethyl Disulphide
Although technology is always evolving, one demand for our products never changes: the demand for customer safety. Whenever we contribute to customer safety, we are presented with an opportunity to develop further. GASTEC holds this corporate creed of safety and development in high esteem, as it strives to grow while always putting customer safety first. Generating calibration gas with a permeation tube.
Generating calibration gas with a permeation tube. Concentration range 0.003 – 0.45 ppm.
*As Permeation tubes have individual differences in permeation rates, the above concentration ranges may differ slightly from the actual range that can be controlled.
Features OF Gastec P-73-H Permeation Tube Dimethyl Disulphide
Ultra-Low Concentration Capability: Capable of generating very low concentrations ($0.003$ to $0.45$ ppm), which is essential for odor threshold studies and high-sensitivity environmental monitoring.
Stable Permeation Method: Uses a high-purity chemical sealed in a fluororesin (FEP) tube. The gas diffuses through the tube wall at a constant, predictable rate when held at a steady temperature.
Gravimetric Reliability: The concentration is determined by the “Weight-Loss Method,” ensuring high accuracy and traceability for analytical laboratory standards.
Safer Alternative: Provides a safer, more manageable way to handle DMDS compared to high-pressure gas cylinders, which can be difficult to stabilize at such low concentrations.
Optimized for PD-1: Specifically designed to fit the tube holders and ovens of the Gastec PD-1B and PD-1C gas generation systems.
