What is chlorine made of?
CHLORINE PRODUCTION: There are three key ingredients to make elemental chlorine; salt, electricity and water. From these three ingredients, we get elemental chlorine (Cl2), caustic (often sodium hydroxide or NaOH) and hydrogen (H2).
How does c18 column work?
How Does HPLC Work?
- A small volume of your sample (in the liquid phase) is injected into your stationary phase.
- A pump moves the liquid down the column using high pressure.
- As the individual components exit the column, a detector measures them.

How do you write chlorine?
Chlorine is a chemical element with symbol Cl and atomic number 17.
What are 2 properties of chlorine?
Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.
What is the H21 project?
H21 is a suite of gas industry projects, carrying out vital work to prove that the gas network can safely transport hydrogen in the future. Over a third of the UK’s carbon emissions are generated by the 83% of domestic homes currently using natural gas for heating and cooking.
What is c17h2no4?
The molecular formula C17H21NO4 may refer to: Cocaine. Cocaine reverse ester. Fenoterol. Hydromorphinol.
What makes C18 different from C4 and C8?
C18, C8, and C4 are all linear alkylsilane phases. C18 is octyldecylsilane and contains 18 carbons bound to the silica. So they have more carbons and a longer carbon chain than C8 (8 carbons) or C4 (4 carbons). Because of the extra carbons, C18 has a larger surface area that the mobile phase has to travel across.
What are the names of the group 18 elements?
The Group 18 elements include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They are referred to as noble gases or inert gases. This means that these elements are chemically inert and do not take part in any reaction. The general configuration of the valence shell is ns 2 np 6 . The exception to this is helium.
Why does C18 have a larger surface area?
Because of the extra carbons, C18 has a larger surface area that the mobile phase has to travel across. This offers more interaction time between the bonded phase and the elutes. Thus the sample elutes more slowly and has more separation.
What kind of engine does a Caterpillar C18 have?
The Cat ® C18 Industrial Diesel Engine is offered in ratings ranging from 429-522 bkW (575-700 bhp)@ 1800-1900 rpm.
