To ensure the consistent qualified products for our costumers, we pay much attention to the QC of our products. All the production will be sampled from batch to batch and analyzed according to the specifications in contract. We have established a QC lab equipped with HPLC, GC and some other instruments.  Our team is skilled in:

      
(1) Pre-shipment sampling and quality control from batch to batch to ensure all the shipments are in accordance with the quality specification in contract.

(2) Screening qualified raw materials suppliers by sampling and testing the samples from the production line of different manufacturers and evaluating the production management of different manufacturers.

(3) Developing qualitative and quantitative (ppm or even ppb) methods for controlling the key impurities of certain products.

(4) Developing analytical methods for technical products and various formulations.
