Dave is correct. The standards most likely contain toluene. A product code can sometimes help. We still have 1 or 2 individuals around who can remember the Nuclear Chicago days.

Subject: Re: Quench standards,
Nuclear Chicago has been out of business for a very long time. The company
was sold to Searle and was splintered and sold to many other
companies. For a while part of the company was called Amersham Searle My
guess is that the standards contain toluene and/or xylene. You might want
to call Amersham with the part number.
