Measuring the salinity or the dissolved salt content of water is important as aquatic organisms, livestock, and crops thrive at different salinity levels. Freshwater has a salinity value of less than 0.5 ppt while seawater has an average salinity of 35 ppt. Introduction Salinity is the measure of the amount of dissolved salts in water. …
A simple extraction procedure using water is recommended for measuring the pH of non-aqueous solutions containing water-immiscible solvents. Water is added and mixed thoroughly with the sample. After reaching equilibrium, the solvent phase is separated and the pH of the water phase is then measured. Introduction 1. Solvents Liquids can serve as solvents to dissolve …
In Africa, power outages (euphemistically known as load shedding) are common. Other disasters, such as floods, more severe storms or large wildfires are also on the increase, mostly due to man’s intrusion and global warming.

Consumers and regulators are concerned about the safety of fruits, vegetables, salad and other ready-to-eat products. This includes preventing contamination from both pathogens and chemical contaminants. In South Africa, chlorine is often used to disinfect the wash water for salads. The use of chlorine can lead to contamination of the product with chlorinated chemicals. As …
October 2018 A new study by the National Science Foundation (NSF) and the US Department of Energy has found that when an El Niño or a La Niña forms in the future, it likely to cause more extreme weather over many land regions – intensifying changes to temperature, rainfall and wildfires. Model simulations of the …
Learn why and how food manufacturers need to measure the sodium (Na+) and salt (NaCl) content in food samples. Why we need to measure and control sodium content in food products: High dietary sodium intake increases the likelihood of developing high blood pressure and heart disease In 2010, 1 out of every 10 cardiovascular deaths …
If you look after the LAQUA Electrodes carefully, they can last for two to three years. It is advisable to keep at least one spare electrode if you do frequent testing. Alternatively, you could order a replacement electrode only when your electrode ages and shows signs of incorrect readings. Replacement of the entire pocket meter …
