Owing to health and safety restrictions, many laboratories are forbidden from placing hydrogen cylinders on their premises. Precision Hydrogen Trace generator from Peak Scientific offers a safe alternative to gas cylinders and provides pure carrier gas in sufficient quantities to supply several GCs concurrently.

Carbon steels is a category of steel, which contains 0.12 to 2% carbon. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced.

Alloy steel is often subdivided into low alloy steel and high alloy steels. Low alloy steels exhibit mechanical properties superior to plain carbon steels due to the addition of alloying elements such as molybdenum, nickel and chromium.

Stainless steels are called as high-alloy steels. Due to the presence of large amounts of chromium in the range of 4 to 30%, they have high corrosion resistance than other steels.
