APPLICATION NOTE

Bovine Muscle – NRC BOVM-1

SUMMARY

The application note summarizes the digestion of BOVM-1, a Bovine Muscle Certified Reference Material using
ColdBlock Digestion Pro Series Technology.

Instrument:	ColdBlock CBM sample digester, chiller, ICP-MS & ICP-OES
Published:	March 2023
Digestion Time:	10 Minutes
Acid Used:	HNO₃ & H₂O₂
Average ColdBlock Recovery vs. CRM:	111% Arsenic 97% Cadmium 96% Lead

METHODOLOGY

Chiller temperature was set to -5°C
0.5g of each sample was weighed and placed into a ColdBlock Digestion vessel
15 mL HNO₃ + 2mL H₂O₂ was added
Sample were digested at 60% power for 10 minutes
Samples were cooled and bulked to 40mL using 2% HNO₃ + 0.5% HCl_v/v

DISCUSSION

Digestions were mostly clear with a inor amount of suspended lipids
Samples were filtered prior to analysis

BOVM-1 is a CRM prepared from Canada Grade A beef. The source of material was boneless hip, commonly denoted Canada Grade A round steak (consisting of 4 major muscles: semi-membranous, semi-tendinosis, biceps femoris and adductor).
