摘要

本工作监测了包装类型和储存温度对校准标准溶液KCl 1M短期稳定性的影响。KCl 1M包装在两种类型的包装中,即高密度聚乙烯(HDPE)和玻璃瓶。在25°C和40°C下监测包装类型和储存温度的影响四周。KCl 1M在HDPE和玻璃瓶中的电导率分别为111.61mS/cm和111.62mS/cm。结果表明,在25°C下,在HDPE和玻璃瓶中的KCl 1M溶液具有良好的短期稳定性,并且两种包装类型之间没有显著差异。然而,在40°C的温度下,玻璃瓶中KCl 1M的短期稳定性优于HDPE瓶。

THE EFFECT OF PACKAGING TYPE AND STORAGE TEMPERATURE ON THE SHORT TERM STABILITY OF ELECTROLYTIC CONDUCTIVITY REFERENCE MATERIALS
In this work, monitoring the effect of packaging type and storage temperature on the short term stability of calibration standard solution KCl 1 M were conducted. The KCl 1M were packaged in two types of packaging i.e., high-density polyethylene (HDPE) and glass bottle. The effects of packaging type and storage temperature were monitored for four weeks at 25 °C and 40 °C. The conductivity values of KCl 1 M in the HDPE and glass bottle were 111.61 mS/cm and 111.62 mS/cm, respectively. The results indicated that the KCl 1M solution at 25 °C in both HDPE and glass bottle were found to be good in short term stability and there was no significant different between the two packaging types. At temperature of 40 °C, however, short term stability of the KCl 1 M in a glass bottle was better than the HDPE bottle.
