A number of factors which might affect the readings of the HAR-600 GCFM were studied: 1. The readings were higher when the filter paper strips were placed between the fron halves of the upper and lower counterparts than when they were placed between the rear halves. No differences in readings were observed when the strips were placed in the middle, the left, or the right areas of the counterparts. 2. The higher the fluid viscosity the lower the reading. Salt water (0.9% NaCl) gave a lower reading than deionized water. 3. Increased room temperature or relative humidity led to higher readings, especially when the fluid volume exceeded 0.2 microliter. 4. More reading time was required for high viscosity fluid, low temperature, and high relative humidity. The HAR-600 GCFM readings and the lengths of ninhydrin-stained areas were compared. Both methods were able to reflect the amounts of serum absorbed.
研究了一些可能影响HAR - 600 GCFM读数的因素：1. 当滤纸纸条放置在上、下对应部件前半部分之间时的读数高于放置在后半部分之间时的读数。当纸条放置在对应部件的中间、左侧或右侧区域时，读数没有差异。2. 液体粘度越高，读数越低。盐水（0.9% NaCl）的读数低于去离子水。3. 室温或相对湿度升高会导致读数升高，尤其是当液体体积超过0.2微升时。4. 对于高粘度液体、低温和高相对湿度，需要更多的读数时间。比较了HAR - 600 GCFM读数和茚三酮染色区域的长度。两种方法都能够反映吸收的血清量。
