  6. MODEL OVERVIEW OBSERVATION RESULTS PROS & CONS STUDY CONCLUSION THE OBSERVED SIGNAL FOR HELIUM – UNEXPECTED UNSTEADY SIGNAL Martin Vicar ‒ The empiric elimination of the water vapour influence EMRP IND12 workshop, 2012

  7. MODEL OVERVIEW OBSERVATION RESULTS PROS & CONS STUDY CONCLUSION THE OBSERVED SIGNALS FOR HELIUM AND WATER Martin Vicar ‒ The empiric elimination of the water vapour influence EMRP IND12 workshop, 2012

  8. MODEL OVERVIEW OBSERVATION RESULTS PROS & CONS STUDY CONCLUSION THE CORRELATION BETWEEN SIGNALS FOR HELIUM AND WATER Martin Vicar ‒ The empiric elimination of the water vapour influence EMRP IND12 workshop, 2012

  13. MODEL OVERVIEW OBSERVATION RESULTS PROS & CONS STUDY CONCLUSION + 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 Martin Vicar ‒ The empiric elimination of the water vapour influence EMRP IND12 workshop, 2012

  14. MODEL OVERVIEW OBSERVATION RESULTS PROS & CONS STUDY CONCLUSION THE RELATIVE DECREASING / INCREASING OF THE HELIUM SIGNAL Martin Vicar ‒ The empiric elimination of the water vapour influence EMRP IND12 workshop, 2012

  15. MODEL OVERVIEW OBSERVATION RESULTS PROS & CONS STUDY CONCLUSION 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?
