Description

The Co element is used in nutritional studies as marker. This paper describes an analytical methodology for Co determination in rumen liquid sample using energy dispersive X-ray spectrometry (EDXRF). 200 μL of the sample were dried at 60 deg C on 6.35 μm Mylar film. Ga was used as internal standard. The excitation was carried out utilizing Mo target X-ray tube (Zr filter) at 30 kV / 20 mA. The acquisition time was 200 s. The accuracy of this methodology was assessed through standard addition method, the recovery obtained was 98.7 % for Co. The detection limit was 0.15 mg / L for this element. (author)
