Do you accept CODs?

Yes. Before your order ships, an accounting representative will contact you with the total amount due.

Technical Questions

Visit our Tech Center for a variety of technical resources, including our Interactive Periodic Table and dozens of helpful guides for spectroscopy and analytical chemistry.

How should I store your standards once they arrive?

Standards should be kept at room temperature (18 to 24°C) unless otherwise stated on the Certificate of Analysis.

My solution arrived frozen. How should I proceed?

Most standards will thaw without effecting the analytes. However, this is not true of all elements. We recommend you contact us with your solution's catalog number and we'll confirm whether it's still safe to use. If it's not, we will gladly replace it, free of charge.

What information is listed on your Certificates of Analysis?

Our ISO Guide 31-compliant certificates include certified values based on two independent methods, traceability to specific NIST SRMs and lots, trace metallic impurities listing the analytical data from all traces, plus all other mandatory information.

What is the expiration date of your standards?

Typically, our expiration dates are no greater than one year. There are many factors that prevent our scientists from endorsing an expiration beyond a year. However, we do offer a purchasing options to keep standards viable for longer than a year. Contact us for details.

What is the shelf life of your standards?

Most standards have an unopened shelf life of at least 24 months — larger bottles can last for up to 10 years or longer. However, once the bottle leaves our patented "Transpiration Controlled" storage center, the shelf life is reduced significantly. This is caused by transpiration.

What is the difference between a standard's shelf life and expiration date?

Shelf life is the amount of time that an unopened standard will last without undergoing chemical or physical changes. Expiration date refers to the amount of time that a standard should remain in use after it has been opened. More information »

Why am I getting low results for Silver (Ag)?

Try to avoid mixing Silver with Chloride. However, if your method requires an HCl matrix, do the following:

  • Keep the solution away from the light
  • Keep the HCl content as high as possible
  • Keep the Ag concentration as low as possible

Consult our Interactive Periodic Table for detailed information pertaining to every spectroscopic element.

What is the difference between Silica and Silicon?

The elemental form of Si is expressed as "Silicon". "Silica" is represented as SiO2 or Silicon Dioxide.

The main component on the (M)SDS does not match the starting material on the bottle and certificate. Why?

Oftentimes the starting material is converted chemically to another form that is listed on the (M)SDS and label. For example, the starting material for Antimony (Sb) is Sb metal. The metal is reacted with nitric acid and tartaric acid to form Antimony Tartrate. Thus, the component on the bottle and (M)SDS is Antimony Tartrate and the starting material listed on the certificate is Sb metal.
