OPSIS LiquidLINE provides solutions for laboratories working in electronics, car, paper, textiles and chemical industries as well as solutions for petroleum and mineral products.

Nitrogen(N) in Coal, Leather, Crude and Refined Oil Determinations
OPSIS LiquidLINE has solutions for determination of the nitrogen content in coal and petroleum oil using a variant of the Kjeldahl process. A known mass of the sample is digested with a mixture of sulfuric acid, distilled followed by a titration.

Ammonia (NH3), Urea-N, Ammonium (NH4) Determinations
Ammonia, sometimes called free ammonia, can be determined with steam distillation followed by titration. Ammonium, fixed ammonia, can be determined by adding alkali prior to the distillation.

Formaldehyde Determinations
OPSIS LiquidLINE has solutions to help when determining formaldehyde in industrial production. Spectrophotometric measurement is used after steam distillation. OPSIS LiquidLINE instrument can be used for the distillation. Examples: Formaldehyde in paints, textiles, and household products.

Extraction to determine RoHS, Plasticisers, Resins, Oil and Other Products
OPSIS LiquidLINE provides instruments for hot solvent extractions. This can also be a sample preparation for further analysis with instruments such as GC or LC.
