Our quality control system consists
of raw material purity control and product
standardization.
Every raw material is strictly analyzed
by the analytical instruments such
as UV, HPLC, GC and etc. for confirming
its purity and inquiring the amount
of by-products and impurities. And
we also check its quality in a way
of synthesizing chromophore for the
raw materials which will be used in
bright colors.
After finishing the whole checking
process, we do apply the raw materials
to the real production.
Since we started our business, we
have considered product standardization
the most important process and have
kept in mind how important the quality
constancy is to maximize the benefit
of our customers. Therefore, the final
product, which is analyzed by spectrophotometer
and standardized by beaker dyeing
test, is strictly controlled to meet
our specification allowances in strength,
shade, lightness, dispersibility and
other fastness and properties.
We keep every lot of product as a
sample and we also keep the data taken
through the product standardization
process as a written document at least
for three years.
We are ready to provide all the information
asked by customers regarding our products.
