Sample preparation is and will always be the most important step in chemical analysis. Numerous techniques, methods, methodologies, and approaches are published in the literature, offering a wide range of analytical tools to the lab practitioner. Analytical scientists all over the world try to develop protocols for a plethora of analytes in various sample matrices. In the past decade advances in sample pre-treatment followed the demand for green chemistry and green analytical chemistry, focusing on miniaturization and automation, using the least possible amount of organic solvents. The question is, how far have we come, and what are the future perspectives? Analytical chemists are invited to share their experience in the field and report on the recent advances in sample preparation approaches.

Abstract: The preparation of a cosmetic specimen in cosmetic science for the purpose of the analytical composition of heavy and toxic metals such as lead (Pb), mercury (Hg), cadmium (Cd) and arsenic (As) is of particular importance due to the difficulty of handling of the sample. There are two main methods of preparation. The first method is the wet digestion of the sample with strong acids such as H2SO4, HNO3, HF, HNO3 / HCl (1: 3) and the combination of strong acid with H2O2. Liquid digestion of the sample under the influence of strong acids damages the organic structure of the sample and converts the carbon into carbon dioxide. The contained metals are oxidized to the highest oxidizing step and converted to soluble salts. A problem with this method is the loss of metals during digestion because it occurs at high temperatures as well as the decrease in the concentration of residual acid. The second method of preparation is the wet liquid digestion of the sample with strong acids in a microwave oven in a closed vessel. The acids which are used, are mainly HNO3 or mixtures of acids such as HNO3-HCl and HNO3-H2SO4. When the sample in the acid's solvent, is exposed to microwave energy then it could be reached temperatures substantially above the boiling temperature of the acid solution. The result is the decomposition of the organic material, the oxidation of the metals and their conversion to soluble nitrates. The advantages of using microwaves are the ability to control the temperature, pressure and loss of metals and thus avoid getting erroneous measurement results.
Title: Sponges and sponge like materials in sample preparation in analytical chemistry

Abstract: As the instrumental advancements in analytical chemistry are limited, much emphasis is placed on sample preparation. To this end, researchers develop new sorbent materials, to improve and replace existing ones, with the ultimate goal to improve current methods and make them more efficient and effective. What seemed like a trend in sample preparation a few years ago it was the use of sponge or sponge-like materials (e.g. foams). These materials possess favorable characteristics, such as negligible weight, open-hole structure, high surface area and variable surface chemistry. On account of these properties their use had been promising but soon this trend reversed. Nowadays, with the development of new base materials, such as melamine, along with the advancement of nanotechnology, this topic has "revived" and various functionalizations have been carried out on such spongy materials. The new materials are used as sorbents in sample preparation in analytical chemistry. This review explores the development of such materials, from the past to the present and into the future and their use in analytical chemistry.
