  • Aflatoxin & ochratoxin sample preparation columns

    Simultaneous Analysis of Aflatoxins and Ochratoxin A - Sample Preparation Aflatoxins and Ochratoxin A are produced by fungi, e.g. Aspergillus and Penicillium species. Therefore both toxin types are found together in many foods and animal feeds, e.g. cereals. Thus it is appropriate to analyze one extract for the occurrence of both mycotoxins in a single step. A significant assistance is the ...

  • Redox properties of nanostructured aniline oxidation products formed under different pH conditions

    A series of aniline oxidation products were produced from the chemical oxidation of aniline by ammonium persulphate under constant pH STAT conditions (pH 1 to 7). Regular granular polyaniline was obtained in the samples prepared at pH 1 to 3, with moderate to high conductivities. The presence of polyaniline was also indicated in a further sample prepared under 'falling pH' conditions. The samples ...

  • Sample Preparation of Glass and Ceramic Materials for Atomic Absorption Analysis

    The analysis of silicate-based glass and ceramics has always been a moderately difficult job, since the components that comprise the glass are usually not stable together in solution. For example, most typical acidic digestions that solubilize silicon will cause calcium fluoride to precipitate. If no fluoride is present, the silicon will not be fully decomposed, and if the solution is ...

  • Best Practices in Marine sample preparation

    When the ocean is dying, the planet is too… Coral reefs are already heavily affected, but the entire marine flora and fauna is threatened by ocean acidification and global warming. According to Australian researchers, greenhouse gas emissions might lead to a “collapse” of marine species and thus of the food chain. 10 to 12% of the species might disappear if the temperature ...

  • Best practices for sample preparation & lipid extraction from various sample

    Lipids play a structural role in organisms, forming cells and organelles’ membranes. Not only do they store energy, but recent studies also showed their role as first and second messengers in signal transduction. As they are implicated in widespread pathologies such as cancer or inflammation, they have become a major concern for the scientific community.Here, we present three case studies ...

  • Automated screening of explosives in soil samples by online SFE-SFC-MS

    There are a large number of explosives-contaminated sites in the US, Europe, and Asia. High levels of explosives in soil can threaten the health of humans, livestock, and wildlife. A number of remediation efforts are underway, which require the analysis of explosives in soil samples. Recently, a new technique was introduced that allows the automated supercritical fluid extraction and SFC ...
