We have five main steps of QC process to ensure the goods quality before shipment at present,
*Melting Point Testing
By drying oven equipment to test the thermal endurance (Such as :OB≤ 220℃, OB-1≤ 300℃)
By liquid chromatography,for OB,OB-1,it should be ≥99%.
To make sure whether the material can dissolve it in organic solution or not,
*Appearance Color Detection,
it can be adjustable to the requirement.
*Color Light testing
By GC equipment, to ensure the finished products to be Red,Blue or White in color effect
Besides above tests ,we other testings,such as,Mesh testing for granular size; Ash testing for impurity etc.
