ALS is an LME Listed Sampler and Assayer (LSA), providing evaluation services for high purity metals such as lead, tin, aluminium and copper.
ALS can provide these services as appointed by the London Metal Exchange (LME), or by direct request from independent parties for LME branding projects.
ALS ensures that sampling and analysis is performed to the standards quoted within LME contracts and that producers who use LME branded material are meeting production targets.
