Luvak employs classical chemical methods to verify material content using the following analytical methods:
Luvak Inc. employs ASTM based techniques for gravimetric determination of ash, graphitic carbon, moisture and volatile components of graphitic products. Loss on ignition (LOI) is available for ceramics and related materials. Chloride, lanthanum, silicon, silver, sulfur, thoria and tin may be determined by gravimetric means in various products.
Phosphorous is routinely determined in nickel plating and alloys. nitrogen-nitrate is determined via colorimetric methods in aqueous leachates and other solutions.
Total nitrogen in resins and nitrogen-nitrate or nitrogen-ammonium content in aqueous solutions is determined via a combination of digestion/distillation/titration methods.
