Abstract

A modified micro-Van Slyke apparatus for analyzing gases in a 25- to 100-microliter sample of blood or other solutions is described. The method is based on the vacuum-extraction principle in which the gases are released for direct manometric measurement. A determination of total CO2 and total O2 content in blood can be completed in about 7 in. A commercial micro-Van Slyke apparatus (Thomas Magna-Matic manometer apparatus) requires 10-15 min for the same determination. The modified Van Slyke can be operated under field conditions without losing accuracy. The modified Van Slyke apparatus has greater reproducibility and accuracy than the commercial model.

摘要

本文描述了一种经过改进的微量范斯莱克装置，用于分析25至100微升血液样本或其他溶液中的气体。该方法基于真空抽取原理，在此原理中，气体会被释放出来以便进行直接的压力测量。血液中总二氧化碳和总氧气含量的测定大约可在7分钟内完成。而使用商用微量范斯莱克装置（托马斯磁力计压力计装置）进行同样的测定则需要10至15分钟。改进后的范斯莱克装置可以在野外条件下操作，且不会损失准确性。与商用型号相比，改进后的范斯莱克装置具有更高的重现性和准确性。
