ChoiceChem Sodium Metabisulfite quality assurance:
(1). ChoiceChem only use high purity raw material
A. Using 99.8% pure imported S. The high purity S allows the generation of very high purity SO2 which is further used to making high purity sodium sulphite than usually obtained.
ChoiceChem sodium sulphite's purity is commonly measured above 98% , which is substantially higher than Chinese national standard of 96%.
B. Using high purity soda ash, the soda ash which ChoiceChem use has an alkali content of more than 99.2%, and NaCl content of less than 0.97%.
Our high purity soda ash help us produce higher purity sodium sulphite, and can avoid impurities (like Cl and Iron), which allows our products to better meet pulp industrial requirements.
(2). Strict Factory Inspection System
All products are tested every 2 hours, and substandard products are allowed to leave the factory. We also have third-party tests carried out every 3 days, to ensure our in-house tests are properly calibrated and accurate.
(3). Strict package and loading system
ChoiceChem only use high quality package and packing the cargo after cooling totally, to avoid expansion caused by SO2. The cargo be loaded in our factory directly, whole loading process be inspected by supervisor.
