I'm a new comer. I just wonder if anyone knows how to detect the collector of HD or D2 using isotope ratio mass spectrometer that is usually used for isotopic ratio analyses of heavier gas (CO2, CO, SO2, etc.) but it equipped with a special collector for hydrogen. For heavier gases, three collectors closer each other were used and they are working properly. There should be fourth collector for hydrogen that is slightly far away from the three. But how can I find the fourth detector and make its signal visible on screen? The software is based on OS/2 Wrap Version 3.
Any comments are welcome and thank you in advance.
