I am an analytical chemist, working as a Sole Trader specialising in performing statistical calculations for analytical chemistry in order to achieve the ISO17025 accreditation or with other purposes as for example the development of new methods.

My work is mainly directed to the statistical evaluation of analytical data, including inter-laboratory studies, precision calculation, uncertainty quantification, accuracy, control chart, stability evaluation and the preparation of reference materials.

I have experience in the development of methods using techniques such as Gas Chromatography (GC), High Pressure Liquid Chromatography (HPLC), X-ray Fluorescence (XRF), Inductively Coupled Plasma (ICP), Atomic Absorption (AA), Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) and Gas Chromatography Mass Spectroscopy (GC-MS) in different industries, for instance petroleum, environmental, pharmaceutical, etc.
