Development of a mobile laboratory - lab in the box. How to identify products of the own brand at the point of sale

摘要

After being notified that foreign draught beers were sold as our own brands in bars, pubs and restaurants a method was developed to identify our products at the POS. A portable photometer with diode array technique using a wavelength spectrum from 372 to 1056 nm connected to laptop was developed. The samples are taken secretly with special equipment and analysed within minutes to avoid changes in the beer matrix. The mobile lab can be installed in any kind of cars by using 12 V-DC. The data coming from the photometer is calculated by The “Unscrambler” statistical software using multivariate data analysis.
