+ SIMPLE METHOD
+ INTERESTING RESULTS
+ CAN BE USED IF HELIUM SIGNAL DECLINES WHEN WATER SIGNAL RISES
– DOES NOT GIVE USEABLE RESULTS FOR CASES WHEN HELUM SIGNAL RISES TOGETHER WTH THE WATER SIGNAL
– WE HAVE NOT THE EXACT THEORETHICAL EXPLANATION ABOUT THE INTERACTION MECHANISM AND PLACE

THE RELATIVE DECREASING / INCREASING OF THE HELIUM SIGNAL
OBSERVATIONOVERVIEW CONCLUSIONMODEL STUDYPROS & CONSRESULTS
Martin Vicar ‒ The empiric elimination of the water vapour influence EMRP IND12 workshop, 2012
THERE EXIST DIFFERENT PHENOMENA WHICH SHOULD BE TAKE INTO ACCOUNT.
SOLUTIONS
CORRECT SIGNAL AS DESCRIBED ABOVE (WHEN POSSIBLE).
CLOSE THE SMALL VALVE OF THE CALIBRATED STANDARD LEAK (ENSURES MORE STABLE CONCENTRATIONS OF THE ATMOSPHERIC GASES).
USE SPECIAL APPARATUS FOR HELIUM LEAKS COMPARISON.
OPEN QUESTIONS
DOES EXIST A THEORETICAL BACKGROUND THAT COULD JUSTIFY OUR EMPIRICAL CORRECTION PROCEDURE?
