Pharmacopoeia column

Target-Motherwort

   
  ●The special column of Leonurus japonicus is based on silica gel with high purity and good mechanical stability, with stable stationary phase and good durability.
   
  ●The uniform and stable density of column bed obtained by filling with unique technology can ensure the highest column efficiency.
  
   ● ensure reliable reproducibility between columns by strictly controlling the surface chemical modification conditions.
    
  ● meet the requirements of pharmacopoeia for chromatographic column matrix, and fully meet the separation requirements of pharmacopoeia for sample detection.
            

The special column of Leonurus japonicus was filled with special polar group bonded silica gel, and the filler was uniform spherical particles. In the separation process under Pharmacopoeia chromatographic conditions, the symmetry of stachydrine hydrochloride peak is good, and thenumber of theoretical plates reaches 18746, which is far higher than the requirement of "the number of theoretical plates should be no less than 6000 according to the calculation of stachydrine hydrochloride peak" stipulated in Pharmacopoeia.
