Audited Supplier Carbon monoxide
We supply carbon monoxide gas with 99.5%, 99.9%, 99.99% purity in 40/50 lit cylinders
GENERALITIES:
Carbon monoxide (CO) gas is formed from the combination of a carbon atom with an oxygen atom. Not only flammable, it is also very hazardous since it is very toxic and odorless. It cannot sustain life and is produced, among other things, from incomplete combustion due to lack of oxygen. It can therefore cause domestic accidents if heating systems are poorly maintained. It is produced on a large scale in industry, in combination with hydrogen, by reforming hydrocarbons, generally natural gas. It is used in large quantities to produce various intermediary organic chemicals, such as acetic acids, isocyanates, formic acid, and also certain polymers such as polycarbonates and polyketones

Main applications
1. Chemicals
Carbon monoxide and synthesis gas are the raw materials in the polycarbonate, polyurethane and oxy-alcohol manufacture based on SMR and ATR processes or on partial oxidation Carbon monoxide is also used in the manufacturing of metal carbonyls.
2. Laboratories & analysis
Carbon monoxide is used in calibration gas mixtures for petrochemical industry; environmental emission monitoring, industrial hygiene monitors and trace impurity analyzers.

FAQ
1.What's your product price?
Because each gas price is depends on the market supply and demand, quantity and purity, it is difficult to give a fixed price. If you have any interested in each gas, pls give your details requirement. I could like to make an offer to you.
2.What's the min order?
Different products have different min order. Please don't hesitate to let me know your requirement.
3.What's the delivery time?
If the cylinder is in stock, and only need to fill gas, the delivery is about 7-10 days ex work after receive the deposit.
If the cylinder need to customize, the delivery is about 15-35 days ex work after receive the deposit. That depends on the quantity.
4.How to check the gas quality?
Firstly, our cylinder will take a treatment (cleaning, drying, vacuum pumping, and replacement before filling gas. In this way, the cylinder inside is clear and dry. Secondly, we will take tests every treated cylinder to assure them inside purity. Thirdly, we will take a test for all of the gas after fill into cylinders. If the tested gas is not up to standard, we will produce it again and not release the faulty product to ex work. At last, we will supply you the gas testing qualified report .
5.All the cylinders can be recycled?
Usually seamless steel cylinder can be recycled to use in 20 years.
The disposable cylinder is only use for one time.
6.Shall we send back the cylinders to China to refill gas again?
Yes, when you ordered our cylinders, next time, you can send back the cylinders to fill gas again. You just need to tell us before you export. We will handle all the import customs clearance formalities.
