    What makes a good calibration gas?

    Alex Singer

    There are two types of measurements made when preparing gas mixtures. The first is measuring what goes into the cylinder (volumetric or gravimetric measurement), and the second is measuring what comes out of the cylinder (measurement based on analysis). The first is relatively simple, as you need to only have:

    Risks and Hazards of Chlorine

    Alex Singer

    CAS no.  (Chemical Abstracts Service Registry Number): 7782-50-5

     

    Description

    Chlorine (dichlorine, diatomic chlorine, bertholite, sodium hypochlorite, molecular chlorine) is a greenish-yellow gas. It has a very pungent odour similar to the smell of bleach. Chlorine is mildly soluble in water, becoming hypochlorous acid and hypochloric acid.

    As chlorine is heavier than air (approximately 2 ½ times), in areas with limited ventilation or air movement it will often accumulate and spread through low lying areas.

    Liquid chlorine will evaporate into the air very quickly. Chlorine combines easily with all gases except for nitrogen and any of the rare gases (excluding xenon). Chlorine itself is not flammable but, being very reactive, it may explode or form explosive compounds when exposed to substances such as ammonia, hydrogen, natural gas or turpentine.

    Often for shipping or storage, chlorine is cooled and pressurized turning into liquid chlorine.

    Risks and Hazards of Hydrogen Sulphide

    Alex Singer

    Hydrogen sulphide (H2S), otherwise known as hydro-sulfuric acid, sulphuretted hydrogen, stink damp, dihydrogen monosulfide, sulfur hydride, hepatic gas, sewer gas, is a naturally occurring gas. A by-product of decomposition, it is found in natural gas, crude petroleum, volcanic gas and hot springs.
