Seafood, in particular fish are a good source of protein and omega 3 fatty acids. As well these beneficial nutrients, seafood can contain trace amounts of different metals. Heavy metals present in water both naturally and introduced to the water system are absorbed by animals living in that environment. While trace elements are found in most seafood, much higher levels are found in predatory sea animals, due to the cumulative effect of their consumption. Analysis of trace metals is important to remain compliant with different countries food laws.
Green leafy vegetables are good for you. They are an easy go to for a range of vitamins and minerals, including vitamin A, E and K, folate, calcium, magnesium, and potassium. While once a less desirable vegetable that needed cartoon sailors to promote it, spinach has gained popularity due to its versatility as an ingredient and nutrient density, even among other green leafy vegetables.
Plant analysis provides important information about the nutritional value, quality, and current condition of plants. Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) are two of the most used laboratory techniques. But these techniques require tedious sample preparation, more expenses, and more time. This led to the development of rapid techniques which can help in on-site decision making.
In any agricultural activity, the first step is soil testing. This gives information about the soil’s fertility and its physical and chemical properties. To obtain such information, analysts use soil test kits for on-site testing. Analysts can then determine if the soil is viable for planting. They can also determine what should be added to the soil to improve its fertility.
For the analysis of organic materials, near-infrared reflectance spectroscopy or NIRS is one of the most used analytical techniques.
