Quantitative Analysis

LGC

Scientists at LGC are highly skilled in the accurate quantification of trace elements in challenging matrices. In addition to carrying out the analyis for clients in our own laboratories we also develop and validate methods for transfer to client's laboratories. Our expertise in this area, combined with an array of modern technologies and detailed knowledge of regulatory issues in the pharmaceutical sector, makes LGC your ideal partner.
