ROUND ROBIN

An annual analytical round robin has been part of WEALA’s activities since 1992.

At first, variability in analytical methods somewhat restricted the usefulness of data comparisons. But labs have tended to grow bigger, become fewer in number and to use more specific, documented procedures.


Most labs participate in various proficiency-testing exercises, whether or not these are required for lab certification. Round robins are always a welcome challenge to dedicated technicians. The general improving trend helps build client confidence.
