If your instrument manual calls for the SRM 2034 holmium oxide HOX solution, (PQA-HOX-01) you can use our HOX solution instead. The SRM 2034 item has been discontinued by NIST but our HOX solution is fully NIST traceable to their published standard. Therefore our HOX solution will be entirely suitable for this purpose.
