Design of a Helium Leak Detector. ... to finally reach the mass spectrometer (MS), where the leak is ultimately detected. The turbopump has separate compression ratios for air and helium, and the mutual difference varies by multiple powers of ten. The turbopump, with its high compression-ratio helps to deviate air from the mass spectrometer ...

H2 blockers are commonly-used medications for gastrointestinal (GI) tract disorders that cause excess stomach acid. You can get some of them over the counter, while others are given with a prescription only. Along with Proton Pump Inhibitors (PPIs), their main action is to inhibit the production of stomach acid. At face value, they are very ...

How Do Gas Detection Sensors Work? The Oxygen Sensor is an electochemical sensor. Any gas which can be oxidized or reduced electrochemically can be detected by means of a fuel based electrochemical sensor. The consumption of oxygen produces a current (µA) which is linearly proportional to the concentration of gas in air.

Southern Cross provides a wide range of M-Pact-O Probe Bars as a solution for our clients. The probe bars come in different lengths, widths, and materials. All of the probe bars have different functionalities and can be used in a variety of scenarios. The most common use is to locate a gas line or buried cable or to sample a gas line.

Owner-occupied single-family residences, legally occupied before July 26, 2009, are not required to have carbon monoxide alarms until they are sold. For more information on the carbon monoxide alarm requirements, contact your local building code official or see the State Building Code Council's Carbon Monoxide Alarm page.

Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000:
