Answer 1

1.The term wave number refers to the number of complete wave cycles of an electromagnetic field (EM field) that exist in one meter (1 m) of linear space. Wave number is expressed in reciprocal meters (m-1).

2.asymmetric stretching :- Simultaneous vibration of two bonds, with opposite atomic motions. While one bond is elongating the other is contracting.

3.Reversed-phase chromatography (also called RPC, reverse-phasechromatography, or hydrophobic chromatography) includes any chromatographic method that uses a hydrophobic stationaryphase. ... This type of technique is now referred to as "normal-phasechromatography".

4.

Sparging may refer to:

• A step in lautering, a process used in brewing beer
• Sparging, a process in the processing of edible oils
• Sparging (chemistry), a process used in chemistry whereby a chemically inert gas is bubbled through a liquid; cf. air sparging.
• 5.which resolves a solute using a solvent system that does not change composition .
• 6.In high-pressure liquid chromatography, this guard column is a short column (typically 1–5 cm), normally packed with the same stationary phase as the analytical column, and placed immediately before the analytical column.
• 7.

  A rotary valve is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes. The common stopcock is the simplest form of rotary valve. Rotary valves have been applied in numerous applications, including:

• Changing the pitch of brass instruments.
• Controlling the steam and exhaust ports of steam engines, most notably in the Corliss steam engine.
• Periodically reversing the flow of air and fuel across the open hearth furnace.
• Loading sample on chromatographycolumns.
• Certain types of two-stroke engines.
• Most hydraulic automotive power steering control valves.
• 8.A reciprocating pump is a class of positive-displacement pumps which includes the piston pump, plunger pump and diaphragm pump. ... In reciprocating pumps, the chamber in which the liquid is trapped, is a stationary cylinder that contains the piston or plunger.
• 9.A logical interface (LIF) Is a software entity consisting of an IP address that is associated with a number of attributes such as a role, a home port, a firewall policy, a home node, a routing group and a list of ports for failover purposes.
