The analytical reliability of the determination of pH, pCO2 and pO2 by the automatic analyzer "ABL 300" (Radiometer) was studied. Control materials were used: Confirm, Acidbasol and Qualicheck in the normal, acid and alkaline sphere, and arterial blood, too. The precision within run and between runs for pH and pCO2 meets the contemporary standards (variation coefficient: pH--below 0.2%, pCO2--below 5%. The precision between runs for pO2 is unsatisfactory by low partial oxygen pressure. The accuracy of the three directly determined indices meets the contemporary standards. The comparative analysis of the results obtained by "ABL 300" and "Corning 178" shows a high degree of correlation between the two apparatuses.
研究了自动分析仪“ABL 300”（Radiometer公司）测定pH、pCO₂和pO₂的分析可靠性。使用了对照材料：正常、酸性和碱性范围内的Confirm、Acidbasol和Qualicheck，以及动脉血。pH和pCO₂的批内和批间精密度符合当代标准（变异系数：pH低于0.2%，pCO₂低于5%）。由于氧分压较低，pO₂的批间精密度不令人满意。三个直接测定指标的准确性符合当代标准。“ABL 300”和“Corning 178”所得结果的对比分析表明，这两种仪器之间具有高度相关性。
