Quality Control System

In our quality control laboratories, employees possessing reliable knowledge and skills, and extensive experience, in chemistry, microbiology and other fields conduct stringent checks in all work processes, from the receiving of raw materials to the shipping of finished products. Regarding the quality control of products, we have thus earned a high degree of trust from customers in a wide range of fields.

Physics and Chemistry Laboratory

 

Instrumental Analysis Laboratory

Physics and Chemistry Laboratory   Instrumental Analysis Laboratory
Here we conduct purity tests and quantitative tests using such techniques as decomposition, distillation, coloring, colorimetry and titration.  

Using advanced analytical instruments related to gas chromatography, high-performance liquid chromatography, liquid chromatography-mass spectrometry, and other techniques, we measure products themselves or separate and measure the amounts of impurities contained in products. We also conduct endotoxin testing using a toxinometer.

 
 

Microbiological Testing Laboratory

 

Stability Testing Laboratory

Microbiological Testing Laboratory   Stability Testing Laboratory

On products and the water used for them, we conduct microbial tests for common bacteria, coliform bacteria, objectionable microorganisms, and more.

 

In order to establish the effective life and storage conditions of products, we conduct accelerated and long-term stability testing. We also do 24-hour monitoring for temperature- and humidity-related abnormalities, and have established a system for promptly dealing with any abnormalities that come to light.
