US PHARMACOPEIA AND EUROPEAN PHARMACOPOEIA OPALESCENCE AND COLORATION SOLUTIONS
 


 

These solutions are specially intended for use in testing Ph Eur and/or USP and monographs. European solutions are produced according to 2.2.1 and 2.2.2 Ph Eur requirements using Ph Eur reagent quality (or better) components and water meeting the Ph Eur monograph requirements for Purified Water.
 


 

Every bottle is delivered with a
 

certificate of analysis.

 

US PHARMACOPEIA AND EUROPEAN PHARMACOPEIA
 

  1. REAGENTS
     

  2. STANDARD SOLUTIONS
     

  3. BUFFER SOLUTIONS
     


 

Solutions for Europe are produced according to specifications given in chapter 4.1 using Ph Eur reagent quality (or better) components and water meeting the Ph Eur monograph requirements for Purified Water.
 

Every bottle is delivered with a
 

certificate of analysis.
 

The product codes are identical to  USP or Ph Eur codes, the desired product is easy to find.

 

VOLUMETRIC SOLUTIONS
 

acc. 4.2.2 OF EUROPEAN PHARMACOPOEIA
 


 

Volumetric solutions are prepared according to the usual chemical analytical methods. The concentration of volumetric solutions is indicated in terms of molarity. Molarity expresses, as the number of moles, the amount of substance dissolved in 1 litre of solution. The molarity of the volumetric solutions is determined by an appropriate number of titrations.
 

The repetability does not exceed 0.2 percent (relative standard deviation).
 

Volumetric solutions are standardised by the methods given in USP or Ph Eur and are delivered with a certificate of analysis.
 


 

The product codes are identical to USP or Ph Eur codes , the desired product is easy to find.
