Why should I use Quality Audit Standards on a regular basis?

Regular use of quality audit standards will help you to:

• Troubleshoot problems with sample batches.
  If your sizer is used as a quality control tool, it is inevitable that an occasion may arise where a batch will appear to be out of specification. In such a situation, confirmation that the sizer is performing correctly will help to eliminate a possible area of doubt.
  For this reason, many companies specify the use of Quality Audit Standards on a weekly or even a daily basis.

• Check and record the consistent performance of particle size analyzers to provide an audit trail for customers and Regulatory Authorities .
  Documentary evidence of good measurement practice is of increasing value for companies seeking to conform to Good Laboratory Practice.

• Check the performance of multiple site installations to ensure harmonisation of results .
  Where companies produce similar products at a number of sites, it is essential that all their particle size analyzers are in agreement. Quality Audit Standards help to provide documentary proof of such agreement.

• Isolate the causes of differences between instruments .
  If two instruments appear to disagree, the use of a Quality Audit Standard with well defined measurement procedures can enable users to establish whether the differences are really due to instrumental differences or are actually due to different measurement or preparation procedures (which is frequently the case).

• Avoid product recall problems.
  Annual performance checks are highly commendable but, in the event of an out-of-specification result, uncertainty arises as to how long an instrument has been out-of-specification.
  In companies where particle size is an important performance parameter, monthly, weekly or even daily checking may be insisted on by customers or Regulatory Authorities.
