New tools for sample preparation and instrumental analysis of dioxins in environmental samples

An important building block to generate phosphatidylethanolamine (PE) is ethanolamine. While plants and algae can synthesise ethanolamine de-novo from serine, mammals cannot and

To study the distribution of lipids, imaging time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a well suited technique as it has a high sensitivity for

particles/nm as a function of particle diameter in nm. Figure 6 Calculation of spICP-MS size distribution from raw data. The spikes are due to particles while the continuous

Validation of both the number concentration and sizing capabilities was carried out at concentrations as low as 10 2 particles mL -1 .The capabilities of spICP-MS as a fast

A particularly advantageous feature is considered the integration of chemical sample preparation on the chip, which could lead to front-end fully integrated analytical systems.

The proper way of designing a preparation protocol is to estimate what are the parameters most distinguishing the analyte in question from the sample matrix. In the ideal case, one is
