The experiment report explained that the blood cells (red & white) and the high sodium caused the silver reading on the AA to be unusually high. This is because the AA used did not have a background correction system needed to compensate for such measurements. However, the AA was calibrated using standard silver solutions so that minus the blood cells and high sodium the silver concentration would be accurate. All of the silver readings were within the linear calibration range of the AA. Because the concentration of blood cells and sodium were uniform among the blood samples, any effect of raising the apparent silver reading would effect all the sample measurements in a uniform fashion. This would have the effect of making the absolute reading of silver higher than normal, but would not effect the relative value of the readings. By normalizing the reading we have expressed the results in a ratiometric (relative) fashion rather than using the absolute values. This simple makes the results "relative", meaning that sample two is x percent higher/lower relative to sample one. Because the background nature of the blood cells, etc. has the same effect on all reading, the effect essentially is cancelled out by normalization. So, yes it is a simple ratio. This is a standard scientific procedure and in no way alters the basic calibration of the AA nor does it render the readings unreliable. I thought we had explained this in the report in enough detail to avoid misunderstandings. Clearly that is not the case. Final comment: the normalization procedure used was reviewed and found acceptable by Dr. Maass, Professor of Chemistry. I am inclined to respect his opinion over that of a student in freshman chemistry. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
