Reacts violently with dental mercury amalgam fillings. Percentages and ppm in gases are normally based on molar ratios (solids are usually mass ratios, liquids may be mass, volume or even mass/volume). So it is 9.36%; however 1% = 10000 ppm (1% of one million parts), so 93600 ppm. GASCO Hydrogen Sulfide (H2S) Calibration Gas also known as Cal Gas, is used for the Calibration and Maintenance of Gas Detectors and Sensors. All of our GASCO Calibration Gas Cylinders ship with a Certificate of Analysis (COA). Fixed H2S gas detector is 24 hours online to detect the hydrogen sulfide and gives sound and light alarm with measuring range from 0 to 50 ppm, 0 to 100 ppm, or 0 to 200 ppm.
