High attention on quality

The Quality Control laboratory is one of the pillars of the business success. It deals with the analysis of raw, semi-finished and finished materials to ensure the highest quality and safety of the product. Coordinated by the Head of Quality Control there’re six highly specialized people who make multiple product’s inspections that the company always conducts with daily regularity since ever. The Quality Control laboratory is also the base of all Research & Development projects.

ORGANOLEPTIC CONTROLS

Our total respect for the statements in the data sheets is the result of a rigorous system that comes out from a statistical study of Dr. Dallavalle presented in 1996 at the International Symposium of Cork in Pavia (PV - Italy) .
The scientific and representative photography of ALL incoming batch is given by the sampling of well 400/800 stoppers or disks .
Every morning our tasters panel make an olfactory test on each flask in order to detect any aromatic deviations in the product.

GC-MS ANALYSIS

The gas chromatographic analyzes are used in advanced analytical chemistry techniques based on the use of a gas chromatograph coupled to a mass spectrometer suitably adapted to their compatibility in order to identify and quantify, through a system of data analysis, the organic substances present in the sample analyzed . Mureddu Sugheri uses specifically the latest generation Agilent 7000 for the determination of T.C.A. and T.B.A. may be present in the cork.
