◇ If t e instrument becomes dirty, wipe it wit a soft clot .

◇ Do not use benzine, paint t inner, etc. to clean t e instrument.

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 ℃).
