I have two questions and would appreciate any advice...

1. We have a Prism II running the original DOS-based software and are
interested in updated software that can run on a newer computer.  I
searched the archives but there has not been much on this since Y2K.  Any
advice on updated software and who to get it from?

2. We are also looking for bulk solid carbon to calibrate with NBS-22 and
use as our lab std for organic carbon measurements.  Of course we are
looking for something with lighter delta carbon values (-25 to -35 ?)...any
advice on suppliers?

Thank you,
