Why is the tubing/sample chamber heated in the Intoxilyzer 8000?

• A. To prevent condensation
• B. To enhance sample accuracy
• C. To lower ambient temperature
• D. To speed up the testing process

Answer: (A)

The tubing and sample chamber in the Intoxilyzer 8000 are heated primarily to prevent condensation from occurring. When a breath sample is collected, moisture from the breath can condense if the temperature of the sample chamber drops below the dew point. This condensation could lead to inaccurate readings, as the presence of liquid water could interfere with the infrared spectroscopy used to measure the alcohol content in the breath sample. By maintaining a higher temperature, the system ensures that the sample remains in a gaseous state, allowing for a more accurate measurement of the alcohol concentration. This heating mechanism is essential because it directly impacts the reliability and accuracy of the test results. Other options may touch on different aspects of the testing process, but the primary reason for heating is to prevent condensation, ensuring that the measurements reflect the true alcohol concentration in the breath sample accurately.
