Tube Arsine 0,05/a (10) | Draeger

The Draeger Tube Arsine 0.05/a (10) is a type of gas detection tube used for measuring the concentration of Arsine (AsH₃), a highly toxic and flammable gas, in the air. These tubes are used in conjunction with a Draeger pump and are designed to provide rapid, reliable, and easy-to-read measurements of Arsine levels in various environments, such as industrial settings, laboratories, or workplaces where Arsine gas may be present.

1. Purpose & Function:

   • These tubes are designed to detect Arsine gas, a compound that is often used in the semiconductor industry, as well as in some chemical and metallurgical processes.

   • The tube provides a qualitative or semi-quantitative measurement of Arsine concentration in the air.

   • The reading is based on the change in color of the reagent inside the tube, which reacts with Arsine gas.

2. Detection Range:

   • The tube is calibrated to detect Arsine in the range of 0.05 ppm (parts per million) per liter of air.

   • The "a" in the product name typically indicates that the tube measures the concentration in a specific amount of air, with "0.05/a" referring to the ability to detect 0.05 ppm of Arsine in one breath sample.

3. Measurement Time:

   • These tubes typically provide fast results, often in about 10 minutes, depending on the specific model and environmental conditions.

   • The exact duration for accurate readings will be stated on the packaging or instruction manual.

4. Volume of Air Sample:

   • The "10" likely indicates the volume of air sampled, which is typically 10 liters.

   • A specific volume of air is drawn through the tube using a Draeger pump, which is then analyzed for Arsine.

5. Method of Use:

   • To use the tube, a Draeger pump (usually a hand-operated pump) is connected to the tube.

   • The pump draws a specific volume of air (usually 10 liters) through the tube.

   • The chemical reagent inside the tube reacts with Arsine, and this reaction causes a color change. The length of the color change is proportional to the concentration of Arsine in the air.

   • The color change can then be compared to a scale on the tube packaging to determine the concentration.

6. Safety Considerations:

   • Arsine is a highly toxic and flammable gas, and exposure to even small amounts can be hazardous to health. It can cause serious effects like nausea, headaches, and even death at higher concentrations.

   • The Draeger Tube helps ensure safe working conditions by providing accurate readings of Arsine gas levels, helping to take preventive action if needed.

7. Storage and Handling:

   • Draeger tubes should be stored in a cool, dry place, and should not be exposed to direct sunlight or excessive heat.

   • The shelf life of the tubes is usually indicated on the packaging. Using expired tubes could lead to inaccurate readings.

8. Applications:

   • The Draeger Arsine detection tube is often used in industries where Arsine is used, such as the semiconductor industry, metal processing, and chemical manufacturing.

   • They are also valuable in situations where Arsine gas leaks or accidental releases might occur, making them crucial in maintaining workplace safety.

9. Product Specifications (Typical):

   • Detection range: 0.05 ppm Arsine

   • Sample volume: 10 liters of air

   • Measurement time: ~10 minutes

   • Pack of tubes: Typically sold in packs (e.g., pack of 10 tubes)

10. Additional Features:

    • Compact and portable: Draeger tubes are small and easy to transport, making them suitable for field use.

    • Easy to read: The color change makes interpretation of results simple, even for users with limited experience.

Advantages:

• Fast results: Gives quick feedback on the presence of Arsine.

• Ease of use: Requires minimal training to operate.

• Accurate and reliable: Provides highly accurate results within the specified range.

• No need for external power: Operates manually with a pump, no electricity required.

Precautions:

• Handling: Care must be taken when using the tubes since Arsine is extremely toxic. Proper protective gear (such as gloves and safety glasses) should be worn.

• Ventilation: Always use the tubes in well-ventilated areas to minimize the risk of exposure.
