Tube Phosphine 50/a (10) | Draeger

The Draeger Tube Phosphine 50/a (10) is a specialized gas detection tube designed for the measurement of phosphine (PH₃) gas concentrations in various environments. Draeger is a well-known brand in the field of industrial safety and environmental monitoring equipment, and their gas detection tubes are widely used for their accuracy, reliability, and ease of use.

Product Overview:

• Type: Gas detection tube for detecting phosphine (PH₃) gas.

• Model: Phosphine 50/a (10)

• Detection Range: 0.1 to 50 ppm (parts per million) of phosphine gas.

• Tube Length: Typically comes in a standard length of around 10 cm, but this can vary depending on the specific tube model and batch.

• Detection Principle: The tube utilizes a chemical reaction between phosphine gas and the reagent inside the tube to produce a color change. The intensity of the color change is proportional to the concentration of phosphine gas, which can be read using a calibrated scale printed on the side of the tube.

Application Areas:

• Industrial Safety: For detecting phosphine in environments where the gas may be present, such as in agricultural settings (fumigation), semiconductor manufacturing, and various chemical processing industries.

• Environmental Monitoring: To assess air quality and detect phosphine in workplaces or outside environments where the gas may be present due to industrial processes.

• Laboratory Use: For controlled measurements of phosphine concentration in research or diagnostic labs.

Key Features:

• Fast and Easy Measurement: The detection tube can be used with a Draeger pump, making it a portable and simple solution for field use.

• High Sensitivity and Accuracy: The tube is designed to detect low concentrations of phosphine, ensuring accurate readings even at very low levels of the gas.

• Visual Color Change: The reagent inside the tube changes color as it reacts with phosphine. The degree of color change indicates the concentration of phosphine in the air.

• Compact and Lightweight: The tube is small and easy to carry, making it convenient for spot checks or testing in various locations.

Instructions for Use:

1. Pump Usage: The Draeger Tube must be used with a Draeger pump (such as the Draeger Accuro or Draeger MiniPump). The pump is used to draw a known volume of air through the tube.

2. Air Sampling: After placing the tube in the pump, you activate the pump to draw air into the tube. A specific volume of air is passed through the tube, and the gas reacts with the reagent inside.

3. Color Development: After the air sample has been drawn through the tube, you will observe a color change along the length of the tube. The length of the color change corresponds to the concentration of phosphine present in the air.

4. Reading the Result: The result is read by comparing the length of the color change to a printed scale on the tube. This scale provides the concentration of phosphine in parts per million (ppm).

Storage and Shelf Life:

• Shelf Life: Draeger gas detection tubes typically have a shelf life of 2 to 3 years from the date of manufacture, but this may vary depending on the specific tube and storage conditions.

• Storage Conditions: The tubes should be stored in a cool, dry place, away from direct sunlight, to ensure accuracy and longevity.

Safety Considerations:

• Hazardous Gas: Phosphine is a toxic and flammable gas, and exposure to high concentrations can cause serious health risks, including respiratory issues, organ damage, and even death. It is crucial to use this tube as part of a comprehensive safety program in environments where phosphine is used or generated.

• Ventilation: Adequate ventilation should be maintained in environments where phosphine is used to prevent the buildup of dangerous gas concentrations.

• Protective Equipment: Always use appropriate personal protective equipment (PPE), such as gloves and eye protection, when handling gas detection tubes.

Additional Notes:

• Calibration: While Draeger tubes are highly accurate, it's recommended to regularly calibrate the Draeger pump and follow standard operating procedures for testing to ensure correct results.

• Cost-Effective: Draeger tubes offer a relatively low-cost and straightforward solution for occasional or spot checks of phosphine gas concentration, compared to more complex electronic gas monitors.

Packaging:

• The Draeger Tube Phosphine 50/a (10) is usually sold in packs of 10 tubes, with each tube intended for a single-use application. The tubes are typically individually sealed for freshness and accuracy.

Conclusion:

The Draeger Tube Phosphine 50/a (10) is an essential tool for any workplace or facility where phosphine gas may be present. It allows for easy, quick, and reliable measurement of phosphine gas levels, contributing to a safer working environment and helping to meet regulatory safety requirements.
