The utility of two brands of 20 ml plastic syringes for storage of hydrogen (H2) samples as obtained in H2 breath tests were studied. Plastipak syringes were found to be significantly better with regard to the stability of the H2 concentration and the variability between the H2 samples. Storage of the H2 samples in Plastipak syringes at 5 degrees C significantly improved the H2 retention, whereas refrigeration of H2 samples stored in Once syringes did not reduce H2 loss. Storage of H2 samples in refrigerated plastic syringes is efficient and reliable for several days if syringes with minimal sample variation are used.
研究了两种品牌的20毫升塑料注射器用于储存氢气(H2)样本(如在氢气呼气试验中获得的样本)的效用。发现Plastipak注射器在氢气浓度稳定性和氢气样本之间的变异性方面明显更好。将氢气样本储存在Plastipak注射器中于5摄氏度下显著提高了氢气保留率,而储存在Once注射器中的氢气样本冷藏并没有减少氢气损失。如果使用样本变化最小的注射器,将氢气样本储存在冷藏的塑料注射器中几天是有效且可靠的。
