Multistage forms, and is detachably connected between each section, and convenient transportation and pick-and-place adsorbent material are also convenient for inside cleaning diffuser.
CN106908398A proposes a kind of atmospheric mercury analyzer reference signal automatic monitoring method, comprising the following steps: sets
Determine the reference signal section of intensity reference value, that is, to set the fluctuation threshold of reference signal；The reference signal fluctuation is set to correspond to
Time cycle；Open mercury measurement of concetration and signal peak calculating process；Within the time cycle, the reference signal is judged
Whether the threshold value is exceeded；If the reference signal without departing from the threshold value, continues the mercury measurement of concetration and signal peak calculates
Process；After the reference signal exceeds the threshold value, the mercury measurement of concetration and signal peak calculating process stop.Using the hair
The bright abnormal conditions that can judge reference signal accurately and in time, system is safeguarded in prompt in time, guarantees that test data is quasi-
Really.
Above-mentioned patent differs greatly with teachings herein, does not influence the new novelty and creativeness of the application.
