Fertiliser Analysis | Elemental Analysis of Fertilizers

Successful, high-yield crop production often depends on the application of fertilizers
to ensure that the correct quantity of nutrients is available to plants during the
growth cycle. Excess amounts of some nutrients can also be detrimental to plant
health, therefore monitoring the quantity of nutrients in fertilizers is essential. Elemental analysis techniques provide valuable information on fertilizer quality. This
information helps to determine the correct quantity of fertilizer to apply to satisfy
the nutrient requirements necessary for optimal crop yield.

Analysis of Food Products | Seafood Analysis

Whether you need to check for harmful chemicals such as biogenic amines, hydrocarbons, drugs, or pesticides inappropriately administered to the water, or marine biotoxins that can accumulate in fish and shell fish, due to algal activity in the water, We offer LC/MS and GC/MS technologies that will provide the sensitivity you need.

Analysis of Food Products | Veterinary Drugs Screening

Foods of animal origin are some of the most challenging for analytical chemists to investigate effectively, particularly for veterinary drugs. The complexity of the matrix and the number of pharmaceutical analogues demands a sophisticated approach to testing, and the different legislative requirements of various countries requires sample referencing that meets a wide variety of regulatory conditions. Protecting human health from banned substances (such as steroids), inappropriate regulated drugs or foods in which substances have exceeded recommended levels is an important issue. In meeting this challenge, we offer LC-MS and GC-MS technologies that effectively detect a range of veterinary drugs, metabolites and transformation products in foods of animal origin.

Analysis of Food Products | Mycotoxins & Biotoxins

Biotoxins, including mycotoxins, phycotoxins (also known as marine biotoxins) and phytotoxins, occur in food through fungal infections, interaction-with or feeding-on other toxic organisms (e.g. algae), naturally produced toxins as a means of protection or through internal processes in the food during storage. Biotoxins can be extremely dangerous to both animals and humans, causing illness and even death when present, and their control in food and animal feed is vitally important. Many biotoxins have relatively large molecular weights, predisposing them often to LC/MS techniques. Our LC/QQQ systems can handle many compounds in one analysis allowing for screening of regulated compounds and others of concern that merit monitoring for human exposure until better characterized by toxicologists. Our high resolution LC/QTOF instruments can offer answers for target quantitation and can perform untargeted acquisition allowing the analyst to investigate more of a sample’s contents allowing for metabolomic studies.

Analysis of Food Products | Elemental Analysis of Foods

Trace elemental analysis of foods is essential to ensure that products are suitable for consumption. Accurate low-level determination of metals is especially important for foods that are consumed on a regular basis, such as grain products like wheat and rice. Analysis of elements such as Pb, Cd, Cr and Ni is important for ensuring product quality.

Soil and Plant Analysis | Elemental Analysis in Plants

The determination of macro and micronutrients in plant tissues is an important measure used to analyze plant nutritional status and to evaluate the possible need for fertilizer supplementation. The analysis of leaves provides the most information for the deficiency or excess of nutrients in plants. This procedure is often performed using spectrochemical techniques such as Flame Atomic Absorption, ICP-OES and ICP-MS.
