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