ABSTRACT

Inductively coupled plasma-mass spectroscopy, known as ICP-MS, is a spectroscopic device that analyzes many elements in the dream table, such as trace elements, minerals and heavy metals, which are basic inorganic things, with high selectivity and sensitivity. Materials collected from living things such as humans, animals, plants, fungi, bacteria, and model organisms constitute biological sample groups. These materials include; body fluids, tissue, cells and many other components. Researchers need specific types of biological samples to perform their work and advance medicine. The analysis of elements in biological samples is very important in terms of clinical and routine analysis. Apart from this, studies that have contributed to the literature in recent years have been carried out as a research and examination subject. The reason why ICP-MS is highly preferred in biological samples is that it has the ability to quickly measure many elements simultaneously, at very low detection limits. Although ICP-MS is highly preferred in biological samples, various difficulties arise in its use. These are low concentrations of the target species in a small amount of samples, matrix effect, contamination and various interferences. The most common is the contamination that may occur during sampling and storage. The materials used in the sample collection stage should be carefully selected to avoid elemental contamination and should be plastic. Plastic materials used in sample preparation and collection should be washed with 2% nitric acid. Samples can be stored for a long time at +4-8 °C with pre-treatment, convert to solution and acidification processes. Apart from this, in order to analyze biological samples with ICP MS, it is necessary to convert the samples into liquid form and remove the majority of their organic components. Biological samples cause matrix effect due to their organic components and high salt content. Digestion of the organic part, dilution up to a certain rate, is effective in reducing matrix interactions. In this sense, sample preparation is the first and most important step in ICP-MS analysis. For this purpose, microwave combustion systems are mostly used in sample preparation. Analyzing the sample by applying the sample directly to the device in ICP-MS devices produced in different designs provides a great advantage in biological samples. ICP-MS, which is highly preferred in routine clinical analyzes and toxicology, is a powerful and analytical device with its high sensitivity and ability to quickly analyze many elements at the same time. In recent years, research with the ICP-MS device has gained momentum in many diseases and pathological conditions.
