Chemist. Shortly afterwards the LGC expanded its research role and moved into a single new laboratory, but still in its traditional central London location. The first major change, after almost 150 years, occurred in 1988 when LGC was designated a Government agency and moved to a new, purpose-built laboratory at Tedding-ton to the south west of London. At this time LGC took on a number of chemistry-related activities previously carried out at NPL, particularly the Office of Reference Materials, and the DTI (Department of Trade and Industry) VAM (Valid Analytical Measurement) programme was established. 

Analytical measurement is of major economic significance with over 10 billion Euros spent annually on chemical analysis in the UK. However, evidence suggests that many analytical measurements are not fit for purpose and that poor quality data represent a major cost and risk to business and society. Consequently, the valid analytical measurement (VAM) programme (Sargent MacKay 1995 Burgess 2000) was set up in the UK by the Laboratory of the Government Chemist. 

In a survey of analysts the top rating indicators of quality were the use of validated methods and the use of reference materials followed by participation in proficiency testing and quality audits. The Valid Analytical Measurement program of the Laboratory of the Government Chemist in the UK lists six aspects of a quality laboratory that mirrors the list given above ...
