Nitrate Testing
A Nitrate Test is a chemical test used to determine the presence of nitrate ion in solution. Testing for the presence of nitrate via wet chemistry is generally difficult compared with testing for other anions, as almost all nitrates are soluble in water.
Phosphorus Testing
Phosphorus (P) is one of the limiting nutrients for crop production in highly weathered soils. Low soil phosphorus concentration hinders crop growth and development and affects agronomic yield. Achieving optimal yield requires a sufficient concentration of available phosphorus in the soil solution.
Ammonia Testing
In wastewater, ammonia can reach high levels due to digestion of nitrogen-containing organic waste. Monitoring of ammonia in wastewater plants is crucial before the effluent is released to prevent damage to local aquatic life.
Pesticide Testing
Before manufacturers can sell pesticides in the United States, EPA must evaluate the pesticides thoroughly to ensure that they meet federal safety standards to protect human health and the environment.
Organic Carbon Testing
A total organic carbon analyser determines the amount of carbon in a water sample. By acidifying the sample and flushing with nitrogen or helium the sample removes inorganic carbon, leaving only organic carbon sources for measurement.
Orthophosphate Testing
Alternatively, measuring total phosphorus requires more sample preparation and specialized equipment for the digestion of the sample. Measuring orthophosphate has become essential to effectively monitoring and removing phosphorus in wastewater.
