2. Refractive Index and imethylformamide ( MF)
concentration
T e instrument is a refractometer t at detects t e Refractive Index of a sample and outputs t e
DMF concentration(%) value on t e display.
(1) What is refractometer?
W en a straw is placed into a glass filled wit water, t e straw appears to bend. W en a straw
is placed into a glass filled wit sugar water, t e straw appears to bend muc more s arply t an
in t e case of water alone. T is p enomenon is known as t e refraction of lig t. T e
refractometer is an instrument t at measures t e Refractive Index by utilizing t is principle
(t e Refractive Index increases in proportion to t e concentration of t e solution), and was
developed by Dr. Ernst Abbe at t e end of t e 19t century.
(2) What is the Refractive Index?
If t e Refractive Index of air under atmosp eric pressure is 1,
t en w en lig t enters mediumχ, t e ratio of t e sine of t e
incident angleαmeasured against t e p ase boundary to t e
sine of t e refracting angleβis called t e Refractive Index of
t e medium χ.
T e Refractive Index varies wit t e wavelengt of lig t and
temperature and is represented as follows:
For example, Refractive Index of water at 20℃ under t e D-line is:
= 1.33299(Generally expressed as nD = 1.33299.)
m T e Refractive Index is based upon t e supposition t at t e Refractive Index in a
vacuum is 1 and is called t e absolute Refractive Index. Generally, owever, t is index
is seldom used.
(3) DMF concentration(%) scale
T e instrument is programmed wit t e DMF(%) scale, based on t e Refractive Index of water
(nD = 1.33299) as t e reference (0%).
(4) Temperature correction
T e Refractive Index of a substance varies wit temperature. T us, w en using a
refractometer to measure t e Refractive Index of a liquid, t e measurement value will vary wit
t e sample temperature.
T e instrument always detects t e prism temperature. T e value of t e measurement is
automatically corrected for temperature by a built-in processor, so t at t e displayed value is
equal to t e value measured at 20 ℃ (provided t at t e sample temperature is wit in t e
range of 5 to 40 ℃).

(2) Installation of the instrument without the sample inlet unit (optional):
Please note t e following w en installing t e instrument to piping or equipment wit out using a
sample inlet unit (optional):
•T e size of t e prism stage of t e instrument is a 3S ferrule.
T e ferrule connection is recommended for installation.
•Install t e instrument so t at t e prism surface is at a rig t angle to t e ground.
•Connect t e unit to t e piping so t at t e sample flow directly contacts t e prism surface.
T e direct flow of samples (and self cleaning solutions) in contact wit t e prism will keep
substances from ad ering to t e prism surface.
•W en installation to a solution tank is preferred, allow t e sample flow to directly contact t e
prism surface.
•T e sample solution must remain in t e temperature range of 5 to 100℃.
•During operation, build up of solids, dirt and/or grease may form on t e prism surface.
W en t is occurs, t e prism surface must be manually cleaned (C "16.Cleaning t e Prism"
