Explanation / Answer

Provides longest detection path length for narrow column -- HETP

Protects separating column in HPLC -- Guard column

Solvent properties -- Bulk property

A solute specific property - Solute property

Z shape detector cell

Typically a plot of instrument response versus time -- Chromatogram

A detector which must scan through the wavelengths to produce a spectrum - Diode array detector

Sequential detector

Used in organic and biochemistry- matrix is charged to exclude certain analytes. -- Affinity chromatography

Based on solubility of a substance in low, medium and high polarity solvents - Partition chromatography

Typically quaternary amine residues -- Anion exchange resin.

Typically polysulphonic acid residues -- Cation exchange resin.

Distance between crests -- wavelength

Wave number -- 1/v

Steradian -- A unit of solid angle

Energy of a beam of electromagnetic radiation that reaches a given area per second -- Radiant energy

Constructive interference -- Two photons together have increased amplitude

Destructive interference --- Two photons together have decreased amplitude

Paraller beam of radiation is bent when it passes a sharp barrier -- Diffraction

Refraction --- percent of incident radiation not absorbed

Photon is bent passing through a media with different refractive index --- refleaction

Gel permeation in a hydrophobic matrix -- Gel filtration

Micellar electrokinetic chromatography ------- >
