OPSIS LiquidLINE provides analytical solutions for laboratories working with Environmental analyses.
Total Kjeldahl Nitrogen (TKN) Determinations
OPSIS LiquidLINE has solutions for determination of total nitrogen (TKN). Examples: total nitrogen in drinking, ground, and surface water, as well as total nitrogen in domestic and industrial waste.
Total Oxidised Nitrogen (T.O.N) Determinations
Total oxidised nitrogen, nitrite (NO2) and nitrate (NO3), can be determined with OPSIS LiquidLINE instruments.
Ammonia (NH3) and 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. Examples: Ammonium in raw, potable and waste water
Total Cyanide Determinations
OPSIS LiquidLINE has solutions to help when determining Total Cyanide. After distillation the test sample is analyzed according to specific application by titration. Examples: Determination of cyanide in drinking, surface and saline waters, domestic and industrial wastes.
Extraction for Total Petroleum Hydrocarbons (TPH) Determinations
Total petroleum hydrocarbons (TPH) are a family of compounds made from crude oil and are found in soils and water. Exposure to TPH can affect human health and, therefore many laboratories around the world are analyzing TPH levels in the environment. OPSIS LiquidLINE provides solutions for extraction of TPH from soil and sediment samples. The samples are then further analysed in a GC or similar instrument.
Extraction for Toxins and Pesticides Determinations
Toxins such as Dioxins and polychlorinated biphenyl (PCB) can be determined by extraction and subsequent analysis. The subsequent analysis is done with GC/MS, GC or HPCL analysis. OPSIS LiquidLINE provides solutions for hot solvent extraction. Examples: PCB’s, Dioxins and other toxins in food, soil and water. Pesticide residues in soil and water.
Digestion Instruments for Phosphate Determinations
OPSIS LiquidLINE has digestion solutions for determination of total phosphorus in drinking, surface and waste waters. The samples are first digested and thereafter analyzed using photometric method.
Determination of Volatile Fatty Acids in Soil and Sludge
OPSIS LiquidLINE has solutions to help when determining Volatile Acids in Soil and Sludge. After steam distillation the test sample is analyzed by potentiometric titration, spectrophotometric or gas chromatographic methods.
Extraction of Oil, Lubricants and Grease
Standard Methods for Examination of Water and Wastewater provides for the use of three test procedures to determine oil and grease concentrations in wastewater samples. OPSIS LiquidLINE provides solutions for hot solvent extraction. Examples: Extraction of oil, lubricants and grease from wastewater and sludge.
Distillation for Phenol Determinations
Phenol can cause problems in the wastewater treatment process, making phenol determination a necessary step in the wastewater treatment process. OPSIS LiquidLINE has solutions to help when determining Phenol. After a first distillation the test samples are analyzed according to specific application by direct colorimetric method.
Distillation for Formaldehyde Determinations
OPSIS LiquidLINE has solutions to help when determing Formaldehyde in water. Spectrophotometrical measurement is used after steam distillation.
