Frequently Asked Questions

We have gathered all of your frequently asked questions about ASI Standards and answered them below. If you have any further questions, please do not hesitate to contact us!

What is the shelf life of your standards?

Most of our standards are good for two years unopened. Some volatile or complex standards can range from six months to two years due to stability issues with some of the elements that may be included or volatility of the matrix. Every bottle has an Expiration Date and all information relative to stability is on the Certificate of Analysis (COA) that is included with every shipment.

Are your standards guaranteed?

What is traceability?

Traceability can be defined as an unbroken record of documentation ("documentation traceability") or an unbroken chain of measurements and associated uncertainties ("metrological traceability"). As used here, the word "traceability" always means "metrological traceability."
