in the event that those agencies do not have appropriate material available. Our
reference material meet or exceed compendial requirements. We also comply with FDA
guidance on reference standards.

|
Q: |
Why are your conductivity standards well above the compendial <645> acceptance
limits? |
|
A: |
It is a technology and stability issue. We have used NIST's formula for a stable
low level standard (25 uS/cm). This standard can be used with ambient levels of
carbon dioxide and is uneffected by changing conditions. This is because the standard
has been pH corrected. Salt solutions such as KCl, or NaCl are significantly impacted
by ambient carbon dioxide levels. This is why ASTM does not specify a solution below
146.93 uS/cm KCl. We are currently in development of lower level aqueous standards.

|
Q: |
Do you make custom standards? |
|
A: |
We continuously evaluate the opportunity to make specific standards. If you have
a standard you would like for PRA to prepare, please complete the information found
here. |
