My first presentation in my life was about container ship in my first year at college in department of Marine and Naval Engineering hope to add some information to you about container ships
Nitrogen cannot be used as carrier gas for GC. How sure are you about that? In this presentation we tackle what we call the “van Deemter indoctrination”. Take a look at our recent accomplishments and convince yourself to give it at try. Particularly now when more and more laboratories are suffering from inconsistent supplies of helium.

Containerships - Pollution - Climate Change - how to reduce CO2 from container ships.
Container ship in the 12,000 TEU (TEU = one standard container of 20 feet) and there is currently ordered 160 of them to companies all over the world, including Maersk. But not one of them have been equipped with smoke purification systems, known as scrubbers.
