APPARATUS AND A METHOD FOR DETECTING AND MEASURING TRACE GASES IN AIR OR OTHER GASEOUS BACKGROUND |
| 摘要 |
<p>An improved drift tube wherein the high voltage electric field is generated as a function of atmospheric pressure. Such variation of the electric field provides good compensation for the effects produced by changes in atmospheric pressure. As a result, the identification of a particular compound at different altitudes is greatly simplified.</p> |
