ABSTRACT
OBJECTIVE: To establish a method for the content determination of 14 elements in Deproteinized calf blood extractives injection. METHODS: Inductively coupled plasma-mass spectrometry (ICP-MS) was adopted. The radiofrequency power was 1 350 W; flow rate of carrier gas (argon) and collision gas (helium) was 1.1 L/min and 4.5 L/min respectively; integration time was 1.5 s; plasma gas flow rate was 18 L/min; depth of sampling was 65 mm; speed of sampling peristaltic pump was 24.0 r/min; data sampling mode was peak-jump acquisition mode; data collection was repeated for 3 times. RESULTS: The linear ranges of Cd, Pb, As, Co, V, Ni, Tl, Ag, Mo, Cu, Cr, Ba and Al were 0.05-50 μg/L (r=0.999 7), 0.05-50 μg/L (r=0.999 7), 0.05-50 μg/L (r=0.999 8)、0.05-50 μg/L (r=0.999 5), 0.05-50 μg/L (r=0.999 5), 0.05-50 μg/L (r=0.999 8), 0.05-50 μg/L (r=0.999 6), 0.05-50 μg/L (r=0.999 5), 0.05-50 μg/L (r=0.999 5), 0.05-50 μg/L (r=0.999 8), 0.05-50 μg/L (r=0.999 6), 0.05-50 μg/L (r=0.999 6), 0.05-50 μg/L (r=0.999 7) and 0.5-70 μg/L (r=0.999 8), respectively. The limits of quantitation were 0.003 1, 0.008 9, 0.016 0, 0.025 0, 0.002 1, 0.006 9, 0.038 1, 0.002 1, 0.005 5, 0.002 0, 0.023 1, 0.005 0, 0.002 0, 0.324 9 μg/L, separately. The limits of determination were 0.000 9, 0.002 7, 0.004 8, 0.007 5, 0.000 6, 0.002 1, 0.011 4, 0.000 6, 0.016 5, 0.000 6, 0.006 9, 0.001 5, 0.000 6, 0.097 5 μg/L, separately. RSDs of precision, stability and repeatability tests were all less than 8%. The recoveries were 87.4%-94.3%(RSD=2.6%, n=9), 110.3%-118.2%(RSD=1.8%,n=9), 89.8%-99.7%(RSD=3.1%,n=9), 77.7%-84.4%(RSD=2.5%,n=9), 105.6%-113.4%(RSD=2.3%,n=9), 106.7%-116.5%(RSD=2.7%,n=9), 89.1%-104.5%(RSD=4.5%,n=9), 105.6%-118.6%(RSD=3.6%,n=9), 77.8%-88.0%(RSD=4.0%,n=9), 106.7%-116.1%(RSD=2.8%,n=9), 88.5%-97.1%(RSD=3.1%,n=9), 80.5%-88.6%(RSD=2.9%,n=9), 85.2%-99.4%(RSD=4.2%,n=9), 97.6%-109.3%(RSD=3.2%,n=9), respectively. CONCLUSIONS: The method is simple, accurate. The precision, stability and repeatability of this method are also good. It is suitable for simultaneous determination of 14 elements in Deproteinized calf blood extractives injection.
