The determination of PH

Weigh a certain amount of samples into test tube, add a certain amount of water, shake and dissolve, determination of the pH used have been calibrated pH meter.

The determination of KF

Use MA-1 intelligent Carle Fischer moisture tester to measure water content

The determination of solubility

Weigh a certain amount of samples into test tube, add a certain amount of water, shake and dissolve, observe the solution.

The determination of UV absorbance

  A certain amount of the sample was weighed to the nearest 0.0001g, into 10ml volumetric flask, after constant volume with pure water, at a specific wavelength by 2cm cuvette was measured by UV spectrophotometer.

Determination of melting point

   Instrument:

   Micro melting point apparatus WRS-2A, Melting point tubes

  Determination of step:

Open switch, stable 20min.

First set the starting temperature than the melting point of the low 10 ℃, heating rate 2 ℃ / min.

The sample was grind as fine as possible and load in a clean, dry melting point pipe ,until the sample was compressed into about 1cm high .When the actual temperature reaches the set temperature and stabilized . Inserted into the capillary with the sample, the simultaneous determination of three.
